Chapter 1
Powder coating is a dry finishing process used to apply a protective and decorative coating to metal surfaces.
Unlike traditional liquid paint, which relies on solvents to keep the binder and filler parts in a liquid suspension, powder coating is applied as a free-flowing, dry powder.
For thermosetting powder coatings, whether decorative or anti-corrosive, the most popular method is electrostatic powder coating.
Therefore, let’s focus on electrostatic powder coating in this discussion.
Electrostatic powder coating leverages the power of high-voltage electric fields or friction to charge the powder particles and the object being coated.
This causes the particles and the object to acquire opposite charges, making the powder particles cling to the object.
After applying the powder, the object undergoes a process of melting, leveling, and baking, which cures the coating into a smooth, durable film.
While thermoplastic powders only need melting and leveling, thermosetting powders require additional crosslinking to form a solid, permanent layer.
Enhancing the powder’s ability to hold a charge can significantly improve the efficiency of the coating process.
The charge a powder particle holds is influenced by several factors. According to Coulomb’s law, the charge on powder particles can be expressed by the following formula:
The charge on powder particles increases with the square of their diameter, meaning larger particles hold more charge.
Using powders with high permittivity also boosts the charge.
Additionally, increasing the electrostatic voltage in the coating process strengthens the electric field, further enhancing the powder’s charge.
These adjustments can lead to a more efficient powder coating process.
There are two primary methods of electrostatic powder coating: high-voltage electrostatic coating and friction electrostatic coating.
High-Voltage Electrostatic Coating: In this method, the powder particles become negatively charged as they pass through a corona discharge needle. They then adhere to the positively charged object. However, due to the Faraday cage effect, the powder may not coat the recessed areas of the object.
Friction Electrostatic Coating: Here, the powder particles become positively charged as they pass through a friction electrostatic spray gun. They stick to the negatively charged object and can coat even the recessed surfaces.
In electrostatic powder coating, the choice between cold and hot spraying depends on the desired film thickness.
Cold Spraying: If the coating thickness is less than 150 micrometers, there is no need to preheat the object. The powder can be sprayed directly onto the surface.
Hot Spraying: For thicker coatings (over 150 micrometers), the object must be preheated above the powder’s melting temperature before spraying.
The typical particle size for electrostatic powder coatings ranges from 15 to 90 micrometers.
The voltage used in high-voltage electrostatic spraying generally falls between 30 and 90 kV, with 40 to 80 kV being most common.
Using too low a voltage can result in poor electrostatic effects, while too high a voltage can pose health and safety risks.
The basic process of powder coating generally involves the following steps: hanging the workpieces, surface pre-treatment (including degreasing, rust removal, and phosphating), powder spraying, baking and curing, cooling, inspection, and unloading.
1.Hanging; 2.Surface Treatment Equipment; 3.Degreasing; 4.Water Rinse; 5.Surface Conditioning; 6.Phosphating; 7.Boiler; 8.Water Dryer; 9.Hot Air Furnace; 10.Coating Machine; 11.Transfer Machine; 12.Automatic Operation; 13.Manual Operation; 14.Cyclone Separator; 15.Bag Filter; 16.Oven; 17.Hot Air Furnace; 18.LPG Supply System; 19.Overhead Conveyor; 20.Unloading
In powder coating, surface treatment (also known as pre-treatment) is essential regardless of the coating method used. This step is crucial for several reasons:
Improving Corrosion and Rust Resistance: Pre-treatment enhances the coating’s ability to protect against rust and corrosion, thereby extending the lifespan of the coated item.
Enhancing Adhesion: It ensures that the coating adheres better to the surface, resulting in a more durable finish.
Ensuring Even Coating: Pre-treatment helps in achieving a uniform coating over the entire surface.
Let’s break down the surface pre-treatment steps:
Table: Comparison of Surface Treatment Processes for Different Metal Materials and Applications
Note: ○ indicates required, × indicates not required.
| Process | Steel Plate (Automotive) | Steel Plate (General Coating) | Steel Plate (Anti-Corrosion) | Cast Iron and Other Alloys (General) | Cast Iron and Other Alloys (Reaction Type) | Aluminum Plate (General) |

Sandblasting or shot blasting uses compressed air to propel sand or steel shot onto the surface of the workpiece.
This process removes rust, oxidation, and other surface contaminants, revealing the bare metal and creating a rough surface that improves coating adhesion.
During storage, transport, and processing, metal surfaces can become contaminated with oils and other substances.
These contaminants, such as rust-preventive oils and lubricants, must be removed before coating.
Degreasing is a critical step because any remaining oil can reduce the adhesion and performance of the coating.
Methods for degreasing include physical (organic solvents), chemical, and electrochemical methods.
Rust removal can be done physically or chemically.
Physical methods include sandblasting, shot blasting, sanding, and brushing.
Chemical methods involve using acids like hydrochloric, sulfuric, or phosphoric acid to react with and remove metal oxides.
Surface conditioning prepares the metal for better phosphating by altering its microstructure.
This is done using conditioners that promote the formation of a fine, uniform, and dense phosphating layer during the phosphating process.
Phosphating creates a water-insoluble metal phosphate layer on the surface.
This layer improves the adhesion of the coating and enhances corrosion resistance, serving as a protective underlayer.
After phosphating, passivation is performed to further enhance the corrosion resistance of the phosphating layer.
This step ensures the coating’s durability and performance.
Once the surface is prepared, powder coating is applied using an electrostatic spray gun. Here’s how it works:
Electrostatic Application: The spray gun charges the powder particles positively, which then adhere to the grounded workpiece due to electrostatic attraction, ensuring an even coating.
Any powder that doesn’t adhere to the workpiece is either collected in a recovery trough or carried to a cyclone separator by air.
The separator collects larger particles at the bottom, while finer particles go to a bag filter system.
Clean air is either exhausted or recirculated.
Recovered powder must be sieved to remove impurities before reuse.
Since recycled powder may contain impurities and moisture, it is typically mixed with new powder in a ratio not exceeding 50%, ideally less than 33%.
Automated lines often handle recycling and mixing automatically.
Fine powder from bag filters should be processed by the manufacturer before reuse.
The design of the spraying booth and recovery system depends on the shape, size, production volume, and type and color of the powder.
Industrial lines often use combined cyclone and bag filter systems to meet production needs.
Choosing the right powder supply device, spray guns, and their arrangement depends on the level of automation, production volume, and workpiece complexity.
Advanced systems use fixed and mobile spray guns controlled by a computer to ensure consistent quality.
For automated powder coating lines, to ensure the quality of the coating, it is necessary to add a touch-up booth (or touch-up station) for re-spraying.
Baking is a critical step where the applied powder melts and forms a solid film.
For thermoplastic powders, baking melts and levels the powder into a film at the required temperature and time.
For thermosetting powders, baking also initiates crosslinking to form a hard, durable film.
The baking temperature and time depend on the powder type, with thermoplastic powders varying widely (200°C to 400°C) and most thermosetting powders curing at 160-200°C for 10-25 minutes.
The required baking temperature is determined by factors like the workpiece material, thickness, and heat capacity.
Due to high baking temperatures, workpieces must cool to below 40°C before handling.
Cooling can be natural or forced. Natural cooling is slower and may lengthen production time, so forced cooling with cold air or water is often used.
For workpieces with high heat capacity, forced cooling ensures quicker handling and better coating quality.
Products like refrigerators, washing machines, fans, air conditioners, and steel furniture typically use natural cooling due to lower heat capacity.
A powder coating line consists of several key components that work together to ensure an efficient and effective coating process. Here are the main components:
The pretreatment system is responsible for preparing the surface of the items to be coated.
This system usually includes wash stations for cleaning and degreasing, rinse stations, and sometimes phosphating or conversion coating stations to enhance corrosion resistance.
After pretreatment, items are dried in a dry-off oven to remove any remaining moisture.
This step is essential to prevent moisture from affecting the powder coating application.
The powder application booth is where the powder is applied to the items.
It is equipped with electrostatic spray guns that charge and apply the powder.
The booth is designed to contain the powder overspray, which can be reclaimed and reused.
The curing oven is used to bake the powder-coated items, causing the powder to melt and form a hard, durable finish.
The oven must maintain a consistent temperature to ensure proper curing.
A conveyor system transports the items through each stage of the powder coating process.
This system ensures that items move efficiently from pretreatment to powder application, and finally to curing.
Additionally, the conveyor system helps to ground the items, which is crucial for the electrostatic powder application process.
Conveyor systems can be overhead, floor-mounted, or even custom-designed to fit specific needs.
The powder recovery system is designed to reclaim and recycle the powder that does not adhere to the items during the coating process.
This system typically includes a cyclone separator and a bag filter to collect and filter out the powder, allowing it to be reused in the process.
Efficient powder recovery systems help reduce waste and improve the overall cost-effectiveness of the coating operation.
The control system manages and monitors the entire powder coating line.
It ensures that each component operates correctly and efficiently, maintaining the desired temperature, speed, and other parameters.
This system helps to optimize the process and ensures consistent quality in the finished products.

The typical voltage for high-voltage electrostatic spraying is between 30 and 100 kV, with most applications using 40 to 80 kV. If the voltage is too low, the electrostatic effect is inadequate. Conversely, if the voltage is too high, it can be harmful to human health and pose other safety hazards.
The line speed for a powder coating line can vary widely based on several factors, including the complexity of the parts, the coating process, and the specific equipment used.
The line speed for a powder coating line typically ranges from 1.2 to 4.6 meters per minute( 4 to 15 feet per minute).
Production rates can vary from 480 to 1,500 parts per hour, depending on the specific setup and operational efficiency.
By optimizing the line speed and setup, facilities can achieve high production volumes while maintaining coating quality.
For a production rate of 600 parts per hour, a line speed of approximately 5 meters per minute can be achieved when each carrier holds two parts.
In high-efficiency setups, a facility can coat up to 1,500 parts per hour, indicating a high line speed and an efficient process.
Increasing line density can significantly impact production.
For example, it can allow for up to 7,680 parts in one 8-hour shift, which translates to 960 parts per hour.
Powder coatings are classified into two main categories: thermosetting powders and thermoplastic powders. Each type has distinct properties and applications.
Thermosetting powders cure through a chemical reaction during the curing process, forming a hard, durable finish.
Once cured, they cannot be remelted.
Here are the common types of thermosetting powders:
Description: Known for excellent adhesion, chemical resistance, and mechanical properties.
Applications: Ideal for indoor applications such as electrical enclosures, appliances, and automotive parts due to their lack of UV resistance.
Description: Offer good UV resistance, flexibility, and durability.
Applications: Suitable for outdoor applications, including outdoor furniture, automotive components, and architectural elements.
Description: Combine the benefits of both epoxy and polyester powders, offering good adhesion and resistance properties.
Applications: Commonly used for indoor applications where UV resistance is not a critical factor.
Description: Provide excellent weather resistance, chemical resistance, and mechanical properties.
Applications: Used for automotive parts, outdoor furniture, and other items requiring a durable and weather-resistant finish.
Description: Known for excellent clarity, color retention, and weather resistance.
Applications: Often used in automotive clear coats and other applications where a high-gloss, durable finish is desired.
Thermoplastic powders do not undergo a chemical change during curing.
They melt and flow when heated and harden upon cooling.
They can be remelted and reshaped multiple times.
Here are the common types of thermoplastic powders:
Description: Offer good chemical resistance, flexibility, and durability.
Applications: Used for coating pipes, wire coatings, and other industrial applications requiring a tough, flexible finish.
Description: Known for excellent chemical resistance and impact strength.
Applications: Commonly used for coating pipelines, playground equipment, and other items exposed to harsh environments.
Description: Provide exceptional toughness, abrasion resistance, and chemical resistance.
Applications: Used for coating metal parts, gears, and other components requiring a durable, low-friction surface.
Description: Offer good chemical resistance and mechanical properties.
Applications: Used in various industrial applications where a durable, chemical-resistant coating is needed.
The temperature ranges for curing ovens used in powder coating processes can vary based on the type of powder, the material being coated, and the specific requirements of the coating process.
Here are the general temperature ranges:
Typical Range: The common curing temperature for most thermosetting powders ranges between 175°C and 205°C (350°F to 400°F)
Epoxy Powder Coatings: Typically cured at lower temperatures within the range of 175°C to 190°C (350°F to 375°F).
Polyester Powder Coatings: Usually require higher temperatures, around 190°C to 205°C (375°F to 400°F).
Hybrid Coatings (Epoxy-Polyester): Generally cured at similar temperatures to pure polyester, around 180°C to 195°C (356°F to 383°F).
Polyurethane and Acrylic Coatings: Often fall within the upper end of the typical range, around 200°C to 205°C (392°F to 401°F).
Metal Substrates: Commonly cured within the standard temperature range.
Heat-Sensitive Materials: Special formulations like UV-curable powders may allow curing at much lower temperatures, which can be as low as 120°C to 150°C (248°F to 302°F).
Thicker coatings may require slightly higher temperatures to ensure complete curing throughout the material.
Proper airflow and even temperature distribution within the oven are crucial for achieving consistent curing results.
Chapter 3
Ensuring consistent coating thickness is crucial in powder coating to achieve optimal performance, appearance, and durability.
The standard thickness for powder coatings typically ranges from 50 to 500 μm.
This range provides adequate coverage and protection for most applications.
The acceptable tolerances for coating thickness measurements are typically between ±1% and ±3% to ensure precision and consistency.
Different industries have varying requirements for coating performance indicators.
Typical indicators include coating flexibility, bending resistance, impact resistance, cupping test performance, adhesion, hardness, gloss, heat resistance, abrasion resistance, water resistance, gasoline resistance, resistance to liquid media, humidity and heat resistance, salt spray resistance, and aging resistance, etc.
We won’t go into detail about the corresponding standards and test methods here.
If you need more information, please contact us.
Chapter 4
powder coating lines can be customized to fit specific production needs.
Customization is a key advantage of modern powder coating systems, allowing them to be tailored to various industry requirements and production volumes.
Custom powder coating lines can include various equipment configurations to meet unique production demands:
Spray Booths: These can be designed to accommodate different sizes and types of parts, including large industrial components or smaller, intricate items.
Curing Ovens: Options for convection, infrared, and UV curing ovens are available, each suitable for different types of coatings and substrates.
Conveyor Systems: These can be customized in terms of speed, load capacity, and path to ensure efficient movement through the coating process
Advanced automation and control systems: These can be integrated to enhance efficiency and precision.
This includes programmable logic controllers (PLCs) and human-machine interfaces (HMIs) that allow for detailed control over the coating process, ensuring consistent quality and reducing material waste.
Automated systems can include features like gun triggering, oscillators, and robots to manage spray equipment efficiently
Pretreatment and Recovery Systems: Custom powder coating lines can also include specific pretreatment and powder recovery systems tailored to the materials and environmental considerations of the operation.
These systems ensure optimal surface preparation and efficient use of coating materials, enhancing overall production quality and sustainability
Environmental and Safety Considerations: Customization can also address environmental and safety requirements, ensuring compliance with industry regulations.
This includes proper ventilation, waste management systems, and safety features to protect workers and the environment
When customizing a powder coating line, it is essential to provide detailed information to the supplier to ensure that the system meets your specific needs.
Here is the key information you should provide:
The types of products to be coated (e.g., automotive parts, furniture, appliances).
Material of the products (e.g., metal, aluminum, glass).
Maximum and minimum dimensions (length, width, height).
Weight of the products to be coated.
The number of parts to be coated per hour or per shift.
Expected growth in production volume over time.
Type of powder coatings to be used (e.g., epoxy, polyester, hybrid).
Desired coating thickness and finish quality.
(Feel free to contact us if you have no idea about these specifications)
Preferred type of conveyor system (e.g., overhead, floor-mounted).
Required speed of the conveyor.
Ambient temperature and humidity levels in the production area.
Specific ventilation or filtration requirements.
Level of automation desired (e.g., manual, semi-automatic, fully automatic).
Specific automation features (e.g., robotic spray systems, automated quality control).
Any specific safety standards or regulations that need to be met.
Requirements for worker safety and environmental protection.
Available space for the installation of the powder coating line (length, width, height).
Any limitations regarding the layout or footprint of the equipment.
In actual production, the items needing powder coating come in various shapes and sizes.
To meet different demands, you often need to change both the type of coating resin and the color of the powder coating.
Changing colors with powder coatings is more challenging than with solvent-based or water-based coatings.
The main difficulty lies in cleaning the coating equipment, spray booth, and recovery systems.
Here are four methods to help you handle color changes more efficiently:
To boost coating efficiency, you can skip recovering the overspray powder.
This means you only need to clean the spray booth, not the recovery system.
Small-scale factories with small batches and multiple varieties often use this method.
They focus on high initial powder application efficiency and clean only the spray booth and powder supply system when changing colors or coatings.
For PCM (pre-coated metal plate) systems, the spray booth is simple and small, making cleaning and color changing easy.
This method suits manufacturers with small batches and frequent color changes, but not most large-scale coating lines.
Use a dedicated set of equipment for each color, including the powder supply system, spray booth, and recovery system.
Replace the entire set when changing colors. There are two setups:
Series Setup: Each color uses one spray booth, arranged in a sequence.
However, powder from booth A can contaminate booths B and C, causing interference.
To minimize this, arrange colors wisely, such as white in booth A, light yellow in booth B, and light green in booth C.
Series Setup: Each color uses one spray booth, arranged in a sequence.
However, powder from booth A can contaminate booths B and C, causing interference.
To minimize this, arrange colors wisely, such as white in booth A, light yellow in booth B, and light green in booth C.
Rapid color change systems use special materials for spray booths to prevent powder adhesion, easy-clean designs, automatic cleaning devices, optimized powder supply systems, and improved recovery systems.
These features aim to complete color changes within 10-20 minutes.
Use different types of coatings together to achieve multi-color finishes.
Chapter 5
The space requirements for a powder coating line vary based on the size and complexity of the equipment, as well as the production volume.
Here are some general guidelines:
The total floor space required for a powder coating line can range from approximately 100 to 1,000 square meters (1,000 to 10,000 square feet).
Smaller lines for lower production volumes may need around 100 to 300 square meters (1,000 to 3,000 square feet), while larger, high-volume operations could require 450 to 1000 square meters (5,000 to 10,000 square feet)
Adequate ceiling height is necessary to accommodate the spray booths and conveyor systems, which can be particularly tall.
A minimum height clearance of 3 to 4.5 meters (10 to 15 feet) is typically required.
For production lines handling aluminum alloy components, vertical powder coating lines are often used to increase efficiency.
In these setups, products are vertically aligned, which can significantly increase the required height.
Therefore, the final height clearance should be designed based on the length of the products.
Feel free to contact us if you’re not sure whether you have enough space to install a powder coating line?
The installation time for a powder coating line can vary depending on the complexity of the system and the site conditions.
Here’s a general breakdown:
Before installation begins, thorough planning and preparation are essential.
This phase includes designing the layout, ordering equipment, and preparing the site.
It can take anywhere from a few weeks to a few months depending on the project scope.
Once the equipment arrives, the actual assembly and installation process can take several weeks.
For a standard-sized powder coating line, expect an installation time of 2 to 4 weeks.
After installation, the system needs to be tested and calibrated to ensure everything operates correctly.
This phase can add an additional 1 to 2 weeks to the overall timeline.
There are several important site preparation requirements to ensure a smooth installation process:
The installation site must have a strong, level foundation to support the heavy equipment.
Concrete flooring is typically required to handle the weight and provide a stable base.
Adequate electrical supply and plumbing connections must be in place.
This includes high power supply for ovens and spray booths, as well as water supply and drainage for pretreatment systems.
Proper ventilation systems must be installed to manage overspray.
This includes exhaust fans and ductwork, to prevent the concentration of powder particles in the air from becoming too high, which can increase the risk of explosions.
Ensure a safe and compliant working environment.
The site must be equipped with appropriate safety measures, including fire suppression systems, emergency shutoffs, and clear evacuation routes.
Chapter 6
Regular maintenance is essential to ensure the long-term efficiency and performance of a powder coating line.
Here are the key maintenance tasks and their frequency:
Spray Guns: Clean the spray gun nozzles, hoses, and powder pumps to prevent blockages and ensure consistent powder flow.
Booth and Surroundings: Wipe down booth walls and ceiling to remove powder buildup and prevent contamination.

Oven Maintenance: Check the calibration and temperature settings, and clean the interior to prevent contamination and ensure consistent curing.
Safety Controls: Test and inspect safety controls, including shutoff valves and interlocks, to prevent accidental shutdowns and ensure safe operation.
Burners and Ignition Components: Check and service the ignition and burner systems in curing ovens.
Combustion Air Supply: Ensure the combustion air supply system is clean and functioning properly.
Calibration: Calibrate all indication and recording instruments to maintain accuracy
Replacement of Worn Parts: Replace any worn parts, such as spray nozzles, deflectors, and powder outlet tubes, to maintain system efficiency.
Training: Regularly train operators in proper maintenance procedures and safety protocols to ensure consistent upkeep and safe operation
The lifespan of powder coating equipment can vary significantly based on several factors, including the type of equipment, frequency of use, maintenance practices, and environmental conditions.
Powder Coating Finishes: Powder coating finishes themselves are known for their durability, often lasting between 15 to 20 years.
This range accounts for proper maintenance and regular use.
High-quality equipment from reputable manufacturers tends to have a longer lifespan.
Investing in robust, industrial-grade components can extend the overall service life of the powder coating line.
Regular maintenance is crucial for prolonging the lifespan of powder coating equipment.
This includes daily, weekly, monthly, and annual maintenance tasks such as cleaning, inspecting, and replacing worn parts
Equipment that is used continuously or at high capacity may experience more wear and tear, potentially shortening its lifespan.
Balancing the load and ensuring the equipment is not overworked can help maintain its longevity.
Harsh environmental conditions, such as extreme temperatures, humidity, and exposure to corrosive substances, can shorten the lifespan of powder coating equipment.
Proper ventilation and climate control can help mitigate these effects.
Keeping the equipment updated with the latest technological advancements can also affect its lifespan.
Regular upgrades and replacements of outdated components can enhance performance and longevity.
Chapter 7
Powder coatings, being solvent-free powders, can avoid the safety issues associated with organic solvents and water pollution problems associated with water-based coatings.
However, powder coatings are not perfect.
They have their drawbacks, such as dust pollution, dust explosions, and electric arcs during electrostatic powder coating.
These issues should not be ignored from both production safety and operator health perspectives.
Although powder coating avoids solvent pollution, dust pollution cannot be ignored.
To prevent dust from spreading and polluting the environment during production and coating, all systems must be tightly sealed.
When changing colors or types of powders in the spray booth, ensure good ventilation in the workshop.
In powder spray booth, it is essential to install powder recovery devices and air purification systems.
Both the air discharged into the atmosphere and the air used in circulation should meet environmental standards.
Additionally, regular cleaning or washing of the floor is necessary to prevent dust from spreading in the workshop.
Table: Routine Inspection and Cleaning Schedule for Electrostatic Powder Coating System
| No. | Part Name or Indicator | Content | Period/day |
|---|---|---|---|
| 1 | Fan bearings and other rotating parts | Dust adhesion or caking | 1 |
| 2 | Fan exhaust volume | Inspection | 7 |
| 3 | Powder concentration in spray booth and work area | Inspection | 7 |
| 4 | Sectional wind speed at the opening of the spray booth | Inspection | 7 |
| 5 | Concentration of recovered exhaust gas emissions | Inspection | 30 |
| 6 | Dust accumulation in the spray booth | Cleaning | Each shift |
| 7 | Coating on hangers | Inspection and cleaning | Anytime |
| 8 | Filter-type recovery device and purifier | Inspection and cleaning | 3-7 |
| 9 | Cyclone recovery device and wet purifier | Inspection | 3-7 |
Before applying powder coatings, metal surfaces must undergo pre-treatment to remove contaminants and improve adhesion.
This pre-treatment often involves chemical processes such as cleaning, degreasing, and etching, which can lead to environmental pollution if not properly managed.
Chemical Waste: The use of chemicals can produce hazardous waste.
Proper treatment and disposal of these chemicals are essential to prevent soil and water pollution.
Wastewater: Pre-treatment processes generate wastewater that contains dissolved metals, oils, and other contaminants.
This wastewater needs to be treated to remove harmful substances before being discharged to comply with environmental regulations.
Common powder coatings have a high ignition temperature.
However, it is still necessary to prevent the risk of fire and explosion.
Powder coating equipment must be grounded properly to ensure static charges are dissipated, preventing fires and dust explosions.
In the coating process, if the spray gun is too close to the workpiece, it can cause short circuits and sparks, leading to fires or explosions.
Although there have been no severe dust explosion incidents reported in powder coating production and use, minor accidents involving sparks and fires have occurred.
Therefore, potential dangers of dust explosions and fires should not be underestimated.
When designing the spray system, the spray booth should have adequate ventilation to keep dust concentration below explosive limits and include pressure relief measures.
This allows for automatic pressure relief in case of dust explosions, minimizing damage.
Regularly clean the powder accumulation in pipelines and recovery systems to prevent secondary disasters.
Powder storage should be located away from the spray booth to avoid being affected by accidental explosions or fires.
Ground all equipment properly to eliminate static charges and prevent dust explosions.
The grounding resistance should be less than 100 ohms.
The main method for applying powder coatings is electrostatic powder coating, using high-voltage electrostatics between 30-100kV.
While the voltage is high, the current is low (0.7mA), which is generally safe for humans.
However, some people are sensitive to high-voltage electrostatics, which can cause startling and secondary accidents.
To avoid such incidents, follow these precautions:
Most resins used in powder coatings have low toxicity, but curing agents are more toxic.
However, when combined into powder coatings, their toxicity becomes very low or almost non-existent.
Animal tests have shown no lethal or harmful symptoms from short-term inhalation, but powder coatings can irritate the eyes and skin.
While powder coatings are not highly toxic, inhaling them can harm the respiratory system and lungs.
Overexposure can cause silicosis.
To mitigate risks:
Curing ovens must have airflow circulation ducts or exhaust pipes to prevent the buildup of volatile or flammable gases.
Regularly inspect and repair pipes, pumps, and valves in oil or gas-fired drying and curing equipment to prevent leaks.
With the rapid development of the aluminum profile industry, many companies have built vertical powder coating lines with vertical baking ovens.
However, these ovens have reported fire incidents. These ovens, reaching heights of 8000mm to bake 6000mm profiles, have high hanging densities.
The higher concentration of volatiles at the top of these ovens can block heating channels over time, leading to fires.
To prevent this, it’s important to regularly cool down and clean the heating channels, removing deposits.
In the design, incorporate safety measures for volatile deposition and removal to avoid blockages.
In the formulation of powder coatings, reduce the use of raw materials with high volatile content at baking temperatures to extend cleaning intervals and improve efficiency.
Chapter 8
The initial cost for setting up a powder coating line can range from $150,000 to $2,000,000.
Small, basic setups may cost around $150,000, while large, fully automated lines with all the bells and whistles can exceed $2,000,000.
Because electricity rates, labor costs, powder prices, and production line power usage vary widely by country and region, actual expenses can differ significantly.
Here, I provide a calculation method for reference, but actual costs should be determined based on your specific situation.
Here is an overview of these costs:
The cost of powder coating material varies depending on the type and quality of the powder used.
On average, the cost is around $8 per kilogram.
With proper utilization and reclaim systems, the cost per part can be minimized.
For example, a kilogram of powder can cover approximately 5.74 square meters at a thickness of 50 μm, resulting in a cost of about $0.10 per part for material.
This includes wages for spray operators, rackers, supervisors, and quality control personnel.
For instance, if the average wage per hour is $15 and you have 13 employees, the total labor cost would be $195 per hour.
When broken down per part, this equates to approximately $0.13 per part
Additional costs such as insurance, uniforms, training, and taxes.
These are added to the direct labor costs and can amount to around $85 per hour, translating to about $0.06 per part
The operation of ovens, spray booths, and other equipment requires significant energy.
For example, the gas/power cost for a midsize professional batch oven might be about $10-$15 per hour.
For a typical run, this could add up to around $40 for drying and curing
Costs associated with chemicals, water and fuel for pre-treatment processes are also significant.
For a batch of 100 small parts, this might cost about $40.
Fixed costs such as building rent, debt, administrative expenses, and maintenance services must be accounted for.
These costs are relatively constant and can be divided by the production rate to determine the cost per part.
For example, a typical fixed cost might be around $600 per hour, equating to $0.40 per part.
When all these costs are combined, the total operational cost per part can be calculated. Here is an example breakdown:
Material Cost: $0.10 per part
Labor Cost: $0.13 per part
Variable Burden: $0.06 per part
Fixed Cost: $0.40 per part
Total Cost Per Part: $0.69
Note: this is a calculation method for reference, the actual costs should be determined based on your specific situation.

Chapter 10
Powder coating is a popular finishing method that offers many benefits.
However, it also has some drawbacks.
Here’s a guide to understanding the pros and cons of powder coating.
No Harmful Chemicals:Powder coatings are free from volatile organic compounds (VOCs) and water.
This means no harmful chemicals are released during the baking and curing process, helping to keep the air clean.
Plus, it eliminates the need for wastewater treatment, making it great for the environment.
Healthier Workplace: Unlike traditional solvent-based coatings, powder coatings don’t pose health risks to workers.
This makes the production and application processes safer and reduces the risk of fires during production, storage, and transport.
Minimal Waste: Powder coatings can be applied in a closed system where any overspray can be collected and reused.
This makes the process very efficient, with some systems achieving up to 99% utilization of the coating material, saving both resources and money.
Thick Coatings in One Go: With powder coating, you can achieve a thick(50-500μm), durable layer in just one application.
This is equivalent to several coats of traditional paint, reducing the number of applications needed and saving time.
It also cuts down on the space and time required for drying between coats.
All-Weather Application: Powder coating is not affected by weather or seasonal changes, making it reliable year-round.
It’s also easy to learn and doesn’t require highly skilled operators.
The process is forgiving, avoiding common issues like sagging or bubbling, which makes it perfect for automated production lines.
Tough and Long-Lasting: Powder coatings use resins with higher molecular weights than those in traditional paints.
This means they provide a tougher, more durable finish that is resistant to chemicals and wear.
Multiple Techniques: While electrostatic application is the most common method, powder coatings can also be applied using fluidized bed, electrostatic fluidized bed, air spraying, and flame spraying techniques.
This versatility makes it suitable for a wide range of applications.
Lots of Options: Powder coatings come in a wide range of colors, textures, and finishes.
They can be used for decorative purposes indoors and outdoors, as well as for heavy-duty anti-corrosion applications.
Expensive Setup: Setting up a powder coating line requires significant initial investment in equipment like spray booths, curing ovens, and recovery systems.
This can be costly, especially for smaller operations.
Space Requirements: The equipment and processes take up a lot of space, which might not be feasible for all businesses.
Thickness Limitations: While powder coating is great for thick layers, applying very thin coatings can be tricky.
Complex Shapes: Coating items with intricate shapes and deep recesses can be difficult, as the powder might not reach all areas evenly.
Heat Sensitivity: The high temperatures required for curing can be unsuitable for heat-sensitive materials.
Energy Use: Curing ovens consume a lot of energy, which can increase operational costs.
Difficult Color Matching: One of the biggest challenges in powder coating is color matching.
Unlike solvent-based and water-based paints, you can’t simply mix pigments to achieve the desired color.
The process takes longer, and some textured finishes can’t be matched with instruments and rely on experience, making it more complex.
Changing Colors: Switching colors during production can be time-consuming and cumbersome, adding to the complexity of the process.
