INJECTION CO-MOLDED EMI/RFI SHIELDING GASKET

摘要

Method for making a conductive gasket (1), and a gasket (1) formed thereby, wherein a first conductive thermoset elastomeric material (2) is applied to the surfaces of a gasket mold defining a cavity and a second non-conductive thermoset elastomeric material (3) is injected into the mold cavity, heated at or near the curing temperature of the second material (3), and the gasket material is cured. Preferably the first conductive elastomeric material (2) is applied by spraying the material onto a mold at a temperature sufficient to cure the material. The gasket (1) provides excellent EMI shielding and low closure force, while being easy and inexpensive to manufacture compared to previously used methods.
