Benefits of Overmolding

Overmolding is a specialized injection molding process that combines two or more thermoplastic materials into a single, integrated component. Overmolding is a complex manufacturing process, but it offers a wide range of valuable benefits:

Seamless material integration
Reduced manufacturing time and cost
Superior durability and bonds
More complex ergonomics, aesthetics and branding
Customizable performance and usability

EXPLORE OUR APPLICATIONS

Synergy to streamline the entire Development and Validation process

At Optimold and Micro Systems, we deliver complete end-to-end manufacturing solutions that go far beyond standard injection molding services. True success—especially at scale—relies on getting the entire process right from the start. Our projects begin with Design for Manufacturability (DfM) guided by DFMEA, followed by pilot runs using 2-cavity molds to validate design, prove functionality, and catch issues early—reducing risk and cost. Only then do we scale to full production tooling, typically 8, 16, or 32 cavities, enabling efficient, high-volume manufacturing with consistent quality and compliance. This integrated approach ensures your project is built for long-term success.
