| Popis: | 107 This study is mainly to discuss the joint strength of the insert injection molding process, improve the general injection molding die to combine the metal stamping and injection molding process, and to discuss the influence of the physical properties of plastic on the join strength of polymer-metal parts, the matel part of inserts injection-molded on the market, and most of them are processed separately, and placed them in the injection machine to join, but most of them have larger product thickness. In this study, combines stamping and injection molding into one process, however, in order to finish the single process of injection and stamping, but the shrinkage rates of metal and plastic are different, the polymer-metal parts are often peeled off, so this study, manufacturing the small-scale structure on the surface of the matel, and use the shrinkage rate of the plastic to increase join strength, so that the metal can be more easily joined on the plastic. The experimental results show that when the metal surface of the anodized metal is joined to the plastic, the shrinkage different of the plastic part and the metal part may cause the polymer-metal are peeled of, but the small-scale structure which are manufacturing by laser engraving process are increases as the shrinkage rate, and the laser engraving process plastic materials are less restrictive in polymer-metal, even the processing time is much lower than the anode treatment process. |
