MADE IN THE USA! In-house precision custom injection, compression, and transfer molding. We use computer-controlled presses to improve quality and repeatability and reduce scrap. In many of your designs, fully automated injection presses can be used.
Products are molded to rigid specifications and tested to your requirements: Industrial, International, and MIL-Spec capability.
Rigid controls are established at all stages of production, combined with 100% inspection and a full-time Quality Assurance Team to follow production from raw material to shipment, assuring consistent quality in your products.
We supply rubber to metal bonding, industrial, FDA, dental, clear, and conductive rubber. We work with a wide range of materials, including Fluorocarbon (both Fluorel and Viton®), Fluorosilicone, Silicone, Urethane, Nitrile, Neoprene, EPR, SBR, and Natural Rubber.
Many of the parts we mold are rubber to metal bonded parts. We also mold sheets or pads of custom formulated rubber for die cutting gaskets to customer specifications, sometimes as thin as .005″ ± .0005″ thick. We mold and inspect with a toolers microscope coating applicator tips with a .008″ to .012″ diameter ID hole in a Silicone and Fluorosilicone rubber for coating optical fiber. We injection mold grommeted tubes with a .010″ to .012″ diameter hole. Our technical and manufacturing teams excel in your most difficult custom molded products. We will take you from your prototype ideas, sampling, and testing into production in the shortest most cost effective way possible. Molds and samples can be supplied in as little as 1 to 2 weeks depending on the complexity of your design.
