Note: Tooling charges may be incurred for some parts. Custom Molded Gaskets Chomerics can mold conductive elastomer EMI gaskets to fit practically any application. With our range of high quality materials and efficient manufacturing systems we can provide attractive choices in price and performance. Chomerics engineers can rapidly optimize gasket designs, at little or no cost, using tools such as finite element analysis (see next page). Prototype development, tooling and part delivery are each performed to meet our customers’ requirements, with adherence to the industry’s highest quality standards. Custom molded elastomer gaskets can include tight corners, retention bumps and other special geometries. Many other features can be added, such as fabric or mesh reinforcement, pressure-sensitive adhesive, fasteners and compression stops. Nonconductive silicone environmental seals can be bonded to or co-molded with conductive EMI shielding elastomers. Representative custom molded elastomer gasket parts are shown here. Contact Chomerics’ Applications Engineering Department to discuss how custom molded conductive elastomer shapes can be designed to meet your application requirements.
