Here are the effective surface finishes for insert molded parts, carefully selected to enhance durability, functionality, and visual appeal in multi-material assemblies.
This standard finish comes directly from the mold without post-processing. It reflects the mold’s surface texture.
Pre-applied textures on the mold create patterns ranging from fine grain to heavy textures.
A non-reflective surface created through medium-grit sanding of the mold. Often chosen for parts where minimal glare and a subtle look are desired.
A high-gloss finish that gives insert molded parts a premium appearance. Common in consumer-facing components that combine metal and plastic.
Used to produce a smooth, consistent matte finish on areas not requiring high gloss. It also helps blend surface transitions between insert and molded material.
A specialized finish technique used to soften the visual and tactile transition between the insert and surrounding plastic, improving product feel and aesthetics.

How can I tell if my project needs insert molding?
If you’re looking to combine metal and plastic in a single part while ensuring durability, insert molding is ideal for your project.
Will insert molding help me save money on manufacturing?
Yes! You’ll save on labor costs since we combine everything into one molding process instead of requiring multiple assembly steps.
I’m worried about the strength of my parts. Can insert molding help?
Insert molding will give you stronger parts than traditional assembly because we securely embed the metal within the plastic structure.
