A numebr of materials can be used in CNC machines, giving you various of options to complete rapid prototyping to production runs of custom complex parts. For your manufacturing needs, we provide instant quotatios of 100+ metals and plastics, and even you can compare prices for different machining materials.
CNC machining leaves visible tool marks during the process of removing portions of the block’s surface to create desired shapes. If don’t want as-machined parts, select a surface finishing for your custom parts. At RapidDirect, we offer several common surface finishes that help improve functionality and aesthetics.

Powder Coat
Also known as powder spraying/oil spraying, this is the process of spraying powder coating on the surface of the part through a high-pressure device, and then baking it in an oven at high temperature for a period of time to make it solidify. This creates a strong, abrasion and corrosion resistant layer that is more durable than standard painting methods. There are a variety of colors and textures to choose from to meet your pursuit of beauty.

Chem Film (Chromate Conversion Coating)
It is the interaction between the atoms on the metal surface and the anions in the medium to form an isolation layer with good adhesion on the metal surface. This compound isolation layer is called a chemical conversion film. The formation of the conversion film can be either a pure chemical reaction between the metal-medium or an electrochemical reaction.
