本研究主要是探討嵌入件射出成型製程接合強度的問題，藉由修改一般射出成型模具將金屬件沖壓與射出成型製程結合，並探討金屬嵌入件與塑膠部件的結合強度，是否與塑膠材料的物性有影響。現在市面上的金屬嵌入件射出成型，大部分是將金屬部件先加工完成，之後放入射出成型機進行結合，而結合方式，多為包覆式射出成型，如電子零件接頭，另一種則射出成型後再用螺絲鎖固，如電子產品面板。包覆式嵌入射出受限產品形狀，而用螺絲鎖固，螺絲鎖固需多一道製程，增加製造成本與生產時間，且產品厚度往往會提高。
本研究將沖壓與射出成型結合，將沖壓成型與射出成型縮短為一個製程，但是為了使射出與沖壓單一製程完成，以往的包覆式結合無法使用，螺絲鎖固又會使製程時間延長，但由於金屬與塑膠收縮率不同，導致嵌入式射出金屬與塑膠常常剝離，本研究在金屬試片表面生成特定結構，利用塑膠收縮率增加接合力，使金屬能更容易被固定於塑膠上。

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.
