<p>A composite obtained by tenaciously uniting and bonding copper or a copper alloy to PBT or PPS. A copper part having a surface which has been adequately roughened by chemical etching and then blackened can be advantageously used. A surface-treated copper piece (1) is inserted into a cavity formed with the movable plate (2) and retainer plate (3) of a mold (10) for injection molding. A specific resin is injected thereinto to thereby obtain a united article. The resin in the resin composition (4) to be used may comprise PBT or PPS. When the resin composition comprises PBT or PPS, it may contain a PET and/or polyolefin resin or a polyolefinresin, respectively, as a minor component. This composition brings about a high injection bond strength. ® KIPO & WIPO 2009</p> |
