ABSTRACT:
A method for forming an EMI shielding gasket gasket. The gasket is a formed-in-place gasket which is deposited by an extruder. The gasket material is a fluent polymeric material having a conductive particles disposed therein. The fluent polymeric material is supplied to the extruder by a material supply system having several canisters and a mixing chamber. The fluent polymeric material is fed to a chamber in the extruder. Pressure is applied to the fluent polymeric material by a pressure supply system which includes a source of positive pressure and negative pressure, and a control module for selectively supplying positive pressure and negative pressure to the extrusion chamber.
