Powder Coating Service

We offer powder coating services to achieve a tough, long-lasting finish with various color selections.

Powder Coating Specification

A completely dry powder paint, a polycarbonate or thermoset polymer, is electrostatically applied to a metal substrate. Unlike conventional liquid paint, powder coating doesn’t require any solvent to hold the binder and filler of the paint in a liquid suspension.

Materials	Colors	Glossiness	Thickness	Surface Texture
Metals	White, Black, RAL and Pantone	Matte, Glossy	50μm to 150μm	Flat/Texture

Advantages

It produces a tough, long-lasting finish
Available in a wide range of colors and finishes
It is solvent-free and emits negligible volatile organic compounds (VOCs)
Provides adequate protection against rust and corrosion Enhances the lifespan of metal parts

Notes

Powder Coating Finish

Powder coating is an advanced surface treatment process where a dry powder is applied onto the metal surface using resins, pigments, and other additives.

The applied powder is electrostatically charged and is usually sprayed onto a pre-prepared surface-more often, metal-but it can also be applied to several other materials, including plastic or wood. The parts are then subjected to an oven, in which the heat melts and fuses the powder at high temperatures to make a very smooth and highly durable coating, thus protecting the material from corrosion, UV rays, and general wear and tear.

Powder finishing entails putting on hold parts by means of a "jig" or "rack." This will leave marks on your part where powder finishing wasn't feasible. If there are areas where you can not approve "jig" marks, please bear in mind to consist of a technical drawing showing these locations.
Remember to indicate in your CAD file whether you want specific part areas to be masked or plugged. As material is applied to the surface during powder coating, all threaded and reamed holes or other critical-to-function surfaces are plugged or masked as standard.
Tolerances are met before the coating finish. We recommend that you ask for clarifications about masking as needed.
Powder coating polymers are usually insulative and offer poor electrical conductivity.

Powder Coating Design Considerations

Can powder coating be applied to all metals?

Powder coating is?most?often?applied?to?steel, aluminum, and iron,?although?most?metals?can?accept?the?powder?coating. For optimal adhesion, the substrate must be clean?of contaminants. It may not work well on materials such as plastic or wood.

Is powder coating environmentally friendly?

Yes, powder coating is?a?lot?more?eco-friendly?compared?to?most conventional?liquid coatings. It contains no?solvent?or?chemical?components within it, and?the?excess?can be recycled?for?more?eco-friendly?finishing.?Moreover,?it?also?tends?to?emit less?volatile organic?compound?fumes, which are?believed?to?be bad for?the environment.

Is powder coating more durable than anodizing?

While?both?provide?very?good?durability,?the?purpose?is?different?for?each?of?them in their application. Powder coating provides a?harder?layer,?which?is?extremely?resistant to scratches, fading, and corrosion, while?the?anodizing?process?deals?more?with?the?development?of an oxide?corrosion-resistant?layer?in?materials such as aluminum. The?decision?will?depend?upon?your?application and?specific?needs?about performance. For more detailed comparison, read our blog: Finishing Showdown: Anodizing vs Powder Coating

Does powder coating provide a smooth finish?

Yes, powder coating?gives?a?finish?that is?uniform?and?smooth?with no?streaks or brush marks. The electrostatic process ensures?a very?even?cover, enhancing?both?the appearance and durability of the coated surface.
