Surface Finishes for Plastic Injection Molding

Improve the surface quality of your plastic injection molded parts with superior finishing options Rapid-MFG offers an extensive list of surface finishes to enhance the aesthetic appeal of your products. These efficient secondary finishes also improve the mechanical quality of prototype and production parts.

GlossyA grade finishes are made using a diamond buffing process and yield shiny and glossy surfaces on injection molded parts.Learn More>>


B grade finishes use grit sandpaper to produce parts with a slightly rougher finish than grade A parts. Custom molded plastic parts that undergo B grade finishing have a matte surface texture.

MatteC grade finishes use grit sanding stones to produce a rough, uneven surface. Injection plastic parts that undergo C grade finishing have a matte surface texture.Learn More>>
TexturedD grade finishes use grit and dry glass beads or oxide to produce a very rough textured finish. Depending on the type of material used, products can have a satin or dull finish.

What are the most common types of injection molding processes?

The traditional thermoplastic injection molding process can be modified to include processes that help to enhance part quality and part design flexibility. Below are some examples:

Thermoset injection molding

Molding with thermoset materials requires heat or chemical means to cross-link polymer chains.


Overmolding is an injection molding process where one material is molded on top of another.

Gas-assisted injection molding

Inert gas is introduced, at high pressure, into the polymer melt at the end of the injection phase of molding.

Co-injection & Bi-injection molding

Injection of two different materials using either the same or different injection locations.

Microcellular injection molding

Use of physical blowing agent, chemical blowing agent (CBA), or mold core-back process to trigger foaming of polymer inside the mold.

Powder injection molding (PIM)

Forming technique for producing small components using powders, typically ceramics (CIM) or metals (MIM), and binding agents
