    • A thin metal casing with plastic parts and a manufacturing method thereof are revealed. A thin metal casing already formed having on one surface processed and coated with a decorative outer layer is provided. A thermoplastic rubber (TPR) adhesive layer is disposed on an unprocessed surface of the thin metal casing. The TPR adhesive layer is synthesized by butadiene-styrene block copolymer and hydrocarbon petroleum resin. Then the thin metal casing with the TPR adhesive layer is set and fixed in a cavity of an injection molding mold. Next plastic parts are formed on the TPR adhesive layer of the thin metal casing by plastic injection molding. The plastic parts are melted and connected to the TPR adhesive layer integrally by pressure and temperature of injection material. Simultaneously a part of the TPR adhesive layer is infiltrated into existing micro concave holes on surface of the thin metal casing.
    • 揭示了具有塑料部件的薄金属外壳及其制造方法。 提供了已经形成的薄金属壳体,其在一个表面上被加工并涂覆有装饰外层。 热塑性橡胶(TPR)粘合剂层设置在薄金属外壳的未加工表面上。 TPR粘合剂层由丁二烯 - 苯乙烯嵌段共聚物和烃类石油树脂合成。 然后将具有TPR粘合剂层的薄金属壳体固定并固定在注塑模具的空腔中。 下一个塑料部件通过塑料注射成型形成在薄金属外壳的TPR粘合剂层上。 塑料部件通过注射材料的压力和温度熔化并连接到TPR粘合剂层。 同时,一部分TPR粘合剂层渗透到薄金属外壳表面上的现有微凹孔中。
