Surface Finishes For Injection Molded Parts

The design of a product goes a long way in determining its marketing success.

What do consumers look for when deciding which molded plastic product to select? The attractiveness of the surface and a quality appearance and feel can influence a customer to choose your product over that of a competitor.

With ICOMold, you can select one of many surface finishes on your custom plastic injection moldedĀ parts.

One advantage of using ICOMold is that we use steel molds rather than aluminum, which gives you many more surface finish options to choose from. Steel can be polished to a higher degree of smoothness to create a more refined surface finish on your injection molded parts.

Surface finish options for injection molding include: Bead blast, etching, matte finish, leather grains, geometric, and graphics, among others.

We use the Yick Sang standards – the Chinese equivalent of the Mold-Tech standards in North America – for texturing. See the table below for our standard surface finishes on plastic injection molded parts. Please let us know if you require a special surface finish – we will gladly work with you to create a custom finish.
