What should I consider when setting up my file for powder coating?

The biggest thing to keep in mind if you want to powder coat your parts is the added thickness of the powder. Powder coating can add anywhere from .007”-.010” to the surface of your part, so design all clearances with the added width in mind. 

The best materials for powder coating are Aluminum 5052 and 6061, and any of our Mild Steels. The powder coat application and finish will be ideal if you can adjust your design to suit any of these materials. 

Check out our powder coating guidelines for more details on how to design with powder coating in mind. And read our blog post on how to optimize parts for powder coating to get the best possible outcome from SendCutSend’s powder coating service.

In Summary

What should I consider when setting up my file for powder coating with SendCutSend?

There are a couple of things to consider. The thickness of the powder coating itself, and your material thickness. Learn more on our Powder Coating Guidelines page.
