What is Powder Coating?
Powder coating is a finishing process that fuses a dry powder to a metal surface. The finish looks similar to paint but can be more abrasion-resistant and tougher than conventional paint. Custom powder coating products are easy to care for since they are resistant to corrosion, scratching, chipping, and splintering.
eMachineShop offers the following textures and colors:- Gloss, Matte, Texture and Metallic.
- Orange, Red, Purple, Pink, Green, Blue, Brown, Tan and Yellow.
Design Considerations
- Mechanical finishing before powder coating is not usually required as the coating covers and smoothes the surface.
- Powder coating typically adds 0.001″ – 0.003″ to each coated surface and slightly rounds edges.
- Textured and matte finishes hide scratches and abrasions better than gloss.
- Deep pockets and inside corners may not be coated due to the electrostatic process.
- Small amounts of powder may accumulate in holes, which may interfere with mating parts and threading. Plugging, redrilling or retapping can optionally be requested.
Powder Coat Textures
Color, texture, and gloss level should be considered when deciding on a powder coat finish.
A gloss powder coat leaves a nice reflection that is not highly defined. High gloss powder coating is reflective and shiny and is available in a gloss black powder coat finish, which is a rich deep black color with a high gloss finish, as well as other colors.
Matte Powder CoatThis type of powder coat is shine-free and often contains a subtly textured surface. A matte black powder coat finish is a flat matte finish and provides good weather and corrosion protection.
Powder coat textures are quite rough and are available in a sand texture, wrinkle texture, and hammered texture. The sand texture is similar to sandpaper, while the wrinkle texture provides a higher surface roughness and a better grip. The hammered texture is comparable to the surface of an orange peel and has higher gloss levels than sand and wrinkle textures.
Powder Coat MetallicA metallic powder coat has a metallic or sparkle effect and is available as bonded or unbonded metallic.

Powder Coat Colors
Most powder coat colors are available also in gloss, matte, metallic, and textured finishes.
Orange powder coat colors are light, slightly yellow shades or deeper and richer hues that are closer to red on the color spectrum.
Red powder coatings range from a bright red gloss finish comparable to a fire hydrant to a richer and darker burgundy-like red matte finish.
Purple powder coatings contain hues between red and blue. A purple matte finish is a lighter shade in comparison to the deeper purple textured finish.
Pink powder coatings vary in shades from medium light to very light. The pink matte finish is softer compared to the vibrant pink metallic finish.
Green powder coat colors range from darker shades of emerald green including matte and metallic to a lighter green textured color, similar to a strong shade of yellow/green.
Blue powder coat colors are available in deep and intense blue metallic and gloss hues, as well as blue matte and blue textured colors.
Brown powder coatings range from a rich deep brown gloss color to a lighter brown matte color, which contains red and yellow undertones.
A tan powder coat is a paler tone of brown. Tan metallic has a brow-yellow undertone compared to tan matte, which has a yellow-green undertone.
Metallic and gloss yellow powder coat finishes have a shiny green undertone compared to the yellow matte and yellow textured finish, which have a brighter yellow hue.
How it works
The powder coating process works as follows:
- First the surface is prepared by cleaning which might be done by washing, sandblasting or any methods that removes any foreign matter.
- Then the powder is sprayed onto the part using an electrostatic spray gun. The gun charges the powder so that it gets attracted to the surface.
- Next the part with powder is placed in an oven for heating so that the powder melts onto the surface.
- Finally the part is cooled and inspected.
Powder coating is environmentally friendly, economical and does not produce volatile organic compounds in the air.
