The surface finish of an injection molded part is a critical feature that directly effects the outcome of your product going to market. Whether an internal or external part, the finish can range from a rough textured surface to a fine polish.  Sometimes cosmetic treatments also play a role in its outcome. Engineers and Product Designers determine the surface finishes of parts based upon the materials used in the manufacturing process, the development or production stage the part is in and end-use applications.

There are numerous thermoplastic resins available for injection molding. Each material offers a variety of features such as durability, flexibility, and strength.  Xcentric Mold  & Engineering offers a robust material selection, therefore there are many surface finish options for your custom plastic injection molded parts.
