What is Plastic Molding?
Plastic molding is a manufacturing process in which raw plastic material is heated until molten, then shaped into a finished or near-finished part using a custom-engineered mold. It is the most widely used method for producing high-volume, complex plastic components across industries including automotive, medical, electronics, agriculture, and consumer products. The three most common forms are injection molding, insert molding, and overmolding.

Frequently Asked Questions
We offer three core plastic molding capabilities: injection molding for high-volume, tight-tolerance plastic components; insert molding, which encases preformed metal components in plastic during the molding cycle to eliminate secondary assembly; and overmolding, which adds a second material layer over a formed substrate for grip, sealing, or aesthetic features.
Yes. This is one benefit of working with us. Most plastic molders don’t stamp metal, and most metal stampers don’t mold plastic. We do both under one roof, so programs combining metal components with injection molding, insert molding, or overmolding are managed by a single supplier. This eliminates vendor coordination, tightens quality accountability, and simplifies the supply chain for OEMs with both metal and plastic elements in their products.
Our quality assurance operates at three levels: DFM analysis before tooling is built to catch design issues early; in-house tooling maintenance to control mold quality throughout the program’s life; and production inspection using photo spectrometers, gloss meters, vision systems, and dimensional gauges. As an ISO 9001:2015 and IATF 16949:2016 certified manufacturer, we apply automotive-grade quality rigor to every plastic molding program regardless of industry.
