SendCutSend Powder Coating Guidelines

Your one-stop shop for everything you need to know about powder coating with SendCutSend.

Order Requirements

Summary:

There is a 20 parts per color minimum for all powder coated orders. If you need more than one color, you will need to order another 20 parts in the additional color.

We recommend placing your powder-coated parts as a separate order from your non-powder coated parts. This will give you the best possible lead time for all your parts.

We are still cutting and shipping your orders at our typical break-neck speed, but keep in mind that powder coating will add 7-10 days to the production time. We know the final look of your parts will be worth the wait!

Materials Available for Powder Coating

Materials have to meet a few requirements for powder coating: they have to be able to hold an electrostatic charge, and withstand high curing temperatures. Because of these requirements, aluminum, mild steel and stainless steel are the best candidates for powder coating.
  • Aluminum (5052, 6061, and 7075 series)
  • AR400/500
  • Cold rolled steel
  • Hot rolled steel
  • Hot rolled pickled & oiled
  • Stainless steel (304 series)

Geometry Requirements for Powder Coating

Summary:

All powder coated parts must be at least 3 square inches. No single dimension can be smaller than 3 inches or larger than 23 inches.

There should be a hole or cutout .063” (1.60mm) or larger in each powder coated part so it can be hung. Any holes or cutouts part of the design should not be less than .040” (1.02mm). Holes smaller than .040” or 1.02mm may “fill” with powder during the coating process.

We can’t plug tapped holes prior to powder coating, so keep in mind that any holes we tap for you will need to be chased with a tap to remove any build up between the threads.

The powder adds between .007” (0.178mm) and .010” (0.254mm) to your final part. Be sure to account for this in any areas of your design with small holes or tight clearances.

We cannot provide etching on any of your powder coated parts as the powder will completely cover them.

Preparing Your Parts for Powder Coating
