Surface Treatment

More than ever, design determines the market success of a product. The attractiveness of the exterior of the part, the quality appearance of the surface, and the pleasantness of the feel are extremely important factors for having the customer choose your product over another. A creative surface finish can make your product stand out in a crowd.

You can specify the surface finish on your custom plastic injection molded parts. You can choose from the many available surface finishes. One advantage we have over our competitors is that we provide steel molds, as opposed to aluminum. Many more surface finish options are available with a steel mold compared to aluminum. Steel can be polished to a higher degree of smoothness to create a smoother surface finish on your parts. There are numerous options for surface finishes, such as bead blast, etching, matte finish, leather grains, geometric and graphics.
