Custom Compression Molding Services

Compression MoldingPoly Seal Industries is a leading manufacturer of custom compression molded products, providing customers with precision molded services for a wide range of industries and applications. Insert molding is also available with your choice of metals including aluminum, brass, bronze, stainless steel and ductile iron. We compression mold all types of elastomeric materials such as BUNA (Nitrile), Butyl, Neoprene, EPDM, natural rubber, silicone, SBR, and urethane among others. We also have the capacity to produce FDA approved food grade and USP Class VI materials. Specific hardness is achievable from 10 Shore A to 60 Shore D on the durometer scale. Our facility is equipped with platens up to 30” x 30”, with an available clamping force of up to 300 tons. We do not outsource any part of our molding process;  we are a manufacturer, not a distributor of product manufactured by others.  We control the entire process in-house, for reliable and cost-efficient results.

Over the past four decades, we have expanded our services to include value added offerings such as special machining and grinding, specialty coating services, and rubber to metal bonding, just to name a few. Our high quality, expert services have been successfully applied in such industries as automotive, military, food and beverage, and healthcare, and we are continually evolving to meet new challenges and industry changes. We meet the highest industry standards with our manufacturing methods and employ lean manufacturing and CPI methodologies.
