COMPOSITE OF METAL WITH RESIN AND PROCESS FOR PRODUCING THE SAME

摘要

An object of the present invention is to obtain a composite in which a copper or copper alloy is securely integrated with and joined to PBT or PPS. A copper product that has been suitably roughened by chemical etching and also blackened can be used favorably. A surface-treated copper piece 1 is inserted into a cavity formed by a movable molding plate 2 and a stationary molding plate 3 of an injection molding mold 10, and a specific resin is injected to obtain an integrated product. PBT or PPS can be used as the resin component of a resin composition 4 that is used here. High injection joining strength is obtained if the resin composition contains, as an auxiliary component, PET and/or a polyolefin resin in the case of PBT, and a polyolefin resin in the case of PPS.
