Abstract

See full text

It is an object to manufacture a composite of a metal part and a resin composition part, which is improved so as to securely join and integrate stainless steel and a resin. A stainless steel part whose surface has been suitably roughened by chemical etching or the like can be used. An integrated product is obtained by inserting a stainless steel piece 1 with its surface treated into a cavity formed by a movable-side mold plate 2 and a fixed-side mold plate 3 of a metallic mold for injection molding 10 and injecting a specific resin. PBT, PPS or an aromatic polyamide resin can be used as the main resin component of a resin composition 4 that is used. 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, a polyolefin resin in the case of PPS and an aliphatic polyamide resin in the case of an aromatic polyamide resin.
