Custom Overmolding

As one of the few custom molders in the United States to offer both plastic and silicone molding in a single facility, Extreme Molding is uniquely positioned to do overmolding for a broad range of consumer and life science applications. Whether we are overmolding plastic with high-performance silicone, embedding electronics in plastic for the latest high-tech device, or putting silicone on top of silicone to make a safer infant pacifier, we have the technical expertise and the enthusiasm to take on the most complex and demanding applications.

Plastic and silicone overmolding requires more than just the right equipment, which we have in our manufacturing facility in upstate New York. It also calls for an extensive knowledge of raw materials and their compatibility, particularly when it comes to factors like shrinkage and temperature requirements. Extreme Molding co-founder Lynn Momrow-Zielinski spent much of her earlier career on the materials side of the manufacturing industry, including several years with ExxonMobil Chemical and GE Silicones. She will work closely with you, along with her business partner, Joanne Moon Duncan, and their team of engineers, to determine the best materials to make your product manufacturable and ensure it meets regulatory and performance standards.

Inventors and engineers also appreciate our flexibility, responsiveness and attention to detail. With our unique, full-service model, you will quickly see why no other company, in the U.S. or overseas, can meet your overmolding needs like Extreme Molding.
