| Applicable Materials | Any metal that can hold an electrostatic charge and withstand the curing temperature (typically ~200°C / 400°F), including Aluminum, Steel, and Stainless Steel. |
| Cosmetic Availability | Excellent. Offers a vast range of colors (RAL matching), finishes (matte, satin, gloss), and special effects (metallics, textures, wrinkles). Provides a high-quality, “factory-finished” look. |
| Visual Appearance | A thick, uniform, opaque, solid-colored layer. The finish is typically very smooth with a slight “orange peel” texture, though it can be specified as a heavy texture or wrinkle finish. Appears very durable and substantial. |
Advantages of Powder Coating Surface Finish
Exceptional Durability
Creates a finish that is much tougher than conventional paint, offering superior resistance to chipping, scratching, impact, and abrasion.
Superior Corrosion Resistance
The thick, non-porous coating provides an excellent barrier against moisture, chemicals, and salt, making it ideal for outdoor and industrial use.
Wide Range of Aesthetics
Offers a huge selection of colors, textures, and gloss levels to meet any design requirement.
Environmentally Friendly
Powder coating is a "green" process with virtually zero VOC (Volatile Organic Compound) emissions, and unused powder can be reclaimed and reused.
Cost-Effective and Efficient
The high transfer efficiency and reclaimability of the powder make it a very cost-effective and low-waste process, especially for production runs.
One-Coat Coverage
A single application is often sufficient to achieve a thick, protective, and decorative finish, simplifying the finishing process.
Powder Coating Design Considerations
Significant Coating Thickness
Powder coating adds a substantial thickness (typically 0.05mm to 0.15mm). This must be accounted for in the design of assemblies. Holes will become smaller and external features will grow larger.
Masking is Essential
All threads, tapped holes, and critical mating surfaces must be identified for masking (plugging or taping) to prevent the thick coating from interfering with assembly.
Faraday Cage Effect
Sharp internal corners, deep recesses, and narrow channels can be difficult to coat uniformly, as the electrostatic charge tends to concentrate on outer surfaces. Generous internal radii are recommended.
Heat Requirement
The part must be able to withstand the curing temperature (around 200°C / 400°F) without warping or degrading. This makes it unsuitable for most plastics or parts with heat-sensitive components attached.
FAQ
Is powder coating better than liquid paint?
For durability, yes. It is generally tougher and more resistant to chipping and scratching. For color range and the ability to create very thin, high-gloss finishes, liquid paint can sometimes have an edge.
How much thickness does powder coating add?
A standard coating is quite thick, typically ranging from 0.05mm to 0.15mm (0.002″ to 0.006″).
Can you powder coat plastic parts?
Generally, no. Most plastics cannot withstand the high curing temperatures required for the powder to melt and flow into a solid coating.
Can you match a specific RAL color?
Yes, absolutely. Powders are available in the full range of RAL colors, which is a key advantage of the process.
How do you protect threads and holes?
We use high-temperature silicone plugs, caps, and tapes to mask all features that must remain free of coating. This is a critical part of our standard process.
What is the "Faraday cage effect"?
This is an electrostatic phenomenon where it’s difficult for the charged powder particles to get into sharp internal corners. Our technicians use advanced techniques to minimize this, but good design (using radii) is the best prevention.
Is powder coating environmentally friendly?
Yes, it is considered a very “green” technology because it contains no solvents (zero VOCs) and excess powder can be collected and reused, leading to very little waste.
Can you create a textured finish?
Yes. A wide variety of textured, sand, and wrinkle finishes are available in powder form, which are great for hiding surface imperfections and providing a durable, non-slip grip.
Will the finish be perfectly smooth?
A standard powder coat finish will have a very slight “orange peel” texture, which is a normal characteristic of the process. Very smooth finishes are possible with special powders and application techniques.
How should I specify powder coating on my drawing?
Be specific about the color and finish. For example: “Powder Coat, RAL 9005 Black, Semi-Gloss, Texture: Smooth.” It is also critical to clearly indicate all features that require masking.

Introduction to Powder Coating
We are one of the best companies that offers surface finish services, and we want to tell you about powder coating. This process uses powder paint to stop rust and make things last longer.
What is powder coating?
Powder coating is a dry method that uses ground-up particles and pigment to make a finish that lasts. Unlike liquid paint, this paint is tough and won’t scratch. The process gives the powder a charge, which makes it stick evenly to the substrate.

What is Powder Coating
Powder coating is a better way to paint than wet painting. It uses a powder made of resin and color. You put this powder on a surface and then heat it up to make a strong, nice-looking finish.
What it means and how it works
The first step is to prepare the surface, which means making sure it is clean. After that, an electrostatic spray gun is used to apply a powder. This gun pulls the powder to the surface. Then, the part is put in an oven to bake. The powder melts and makes a smooth, long-lasting finish.
Michael Green, an expert in coatings, says, “The electrostatic application makes sure that the coat is even, even on shapes that are hard to work with.” Powder coating is great because it makes things even.
Important Materials and Substrates
Powder coating can be used on a lot of different materials, such as metals, plastics, and wood composites. The most common type is metal because it can handle high heat. We can coat materials that don’t handle heat well now, though.
- Aluminum, steel, and galvanized steel are all metals.
- Plastics: Some kinds of plastic can be coated, but only if they can handle heat.
- Wood composites: some wood products can be powder coated, which makes them last longer.
Powder Coating vs. Regular Painting: A Comparison
Powder coating is better than painting in a lot of ways. It lasts longer, is better for the environment, and gives you more design options. Powder coating is better for the environment than wet paint because it doesn’t have solvents or VOCs.
“Powder coating provides a tougher finish than traditional paint, resisting chipping, scratching, and fading.”
| Characteristics | Powder Coating | Conventional Painting |
|---|---|---|
| Durability | High | Moderate |
| Environmental Impact | Low | High (VOCs) |
| Aesthetic Flexibility | High (various textures, colors) | High (wide range of colors) |
The Custom Powder Coating Surface Finish Service Process

Preparing the surface is an important step. It involves cleaning and, if necessary, blasting to get rid of dirt or flaws. We also use conversion coatings to make things stick better and last longer.
A strong bond between the substrate and the powder coating needs good surface preparation. This makes sure that the finish lasts a long time.
How to Use Powder
We use high-tech methods to apply the powder coating, such as electrostatic spray and fluidized bed methods. The shape of the part, the finish you want, and the needs of the project all play a role in the choice.
Electrostatic spray works well on parts that are hard to reach or have a lot of details. It is very precise.
Curing and After Treatment
After the powder is applied, the parts are cured in an oven that is kept at a certain temperature. This melts the powder and makes a strong, even coating. After they cool down, the parts are checked for quality and consistency.
Our curing and post-treatment make sure that the finished product is strong and of high quality. It’s ready for a lot of different uses.
