再利用塑料射出成型工艺， 在所述的外表膜 10的内表面， 即内粘着层 13 上射出成型一塑质薄壳件 20;其中所述的塑质薄壳件 20可凭借射出成型时射出 料 20a的射出压力以及温度， 以与所述的内粘着层 13热熔结合成一体， 并同时 迫使所述的内粘着层 13(厚度约 40-60 μηι )的部分厚度（约 10-20%,即 4- 12μπι ), 得渗透至所述的中间吸附隔热层 12中既有的孔隙中， 以对射出料 20a的射出压 力以及温度产生有效的分散作用， 也就是所述的中间吸附隔热层 12可凭借其结 构体既有的孔隙以吸附所述的内粘着层 13的部分厚度， 并凭借其结构体所具有 的适当密度以隔离射出料 20a的射出压力以及温度，达成分散射出料 20a的射出 压力以及温度的功用， 避免射出料 20a的射出压力以及温度冲抵至所述的外饰 层 1 1致破坏所述的外饰层 1 1的完整性； 又在射出成型过程中， 也同时凭借所 述的射出料 20a的流动以迫使所述的外表膜 10形成整平状态， 以形成一密着强 度以及品质都良好的塑质薄壳件复合体 1 ; 由于所述的模穴 31的周缘界线 32是 超出所述的塑质薄壳件 20的周缘界线 21并形成一环周缘且较薄 （有落差） 的 溢料区 33，因此所述的溢料区 33即可在所述的塑质薄壳件 20的周缘界线 21外 缘延伸形成一较薄的凸缘 22如图 6所示，也就是在射出成型的塑质薄壳件 20(尚 未去除毛边之前）的外缘端上额外形成一较薄且一体成型的凸缘 22, 可当作所述 的塑质薄壳件 20成型物所具有的预设的毛边， 供在后续的毛边去除作业中再予 以去除； 另， 随设计需要如欲在所述的射出成型的塑质薄壳件 20的内表面 23 上直接安装电子构件如电路板等， 可在射出成型所述的塑质薄壳件 20时在所述 的内表面 23上同时射出成型所需的结合件 24如图 3、 4所示， 使结合件 24随 塑质薄壳件 20时射出成型而形成一体式结构体；
待冷却定型后， 由射出成型模具 3中取出已射出成型完成的塑质薄壳件复 合体 1 ;
再进行毛边去除作业， 由所述的塑质薄壳件 20的周缘界线 21切除所述的 模穴的溢料区 33所形成的凸缘 22如图 6所示， 即完成一具有外表膜 10以及塑 质薄壳件 20并结合成一体的塑质薄壳件复合体 1如图 2-4所示。
上述使用本发明的外表膜 10以制成一塑质薄壳件复合体 1的应用方法， 由 于本发明外表膜 10的内粘着层 13的部分厚度可在射出成型过程中渗透至所述 的中间吸附隔热层 12中既有的孔隙中， 并同时与塑质薄壳件 20稳固地热熔密 着结合成一体， 故所制成的塑质薄壳件复合体 1中所述的外表膜 10与塑质薄壳 件 20之间的结合能保持相当良好的密着性， 在经实体试验后， 证明所述的外表 膜 10具有足够的抗剥离性， 故本发明的外表膜 10确实可增进所形成一体化塑 质薄壳件复合体 1的结构强度。
又在本发明外表膜 10的应用方法上， 特别在所述的模穴 31的周缘界线 32 的外缘设计一环周缘且较薄 (有落差）的溢料区 33， 当射出成型时， 射出料 20a 一般是由所述的模穴 31之中央部位进入模穴 31， 即灌注口设在所述的模穴 31 之中央部位， 再住四周的周缘界线 32辐射状流动以能较快速地流至所述的模穴 31的周缘界线 32 , 则射出料 20a由中央部位朝向周缘界线 32流动时， 可相对 压迫设在所述的周缘界线 32处的外表膜 10，也就是射出料 20a的流动可驱使设 在所述的周缘界线 32处的外表膜 10向外伸张， 相对产生一种由内向外的整平 效果， 且一直延伸至溢料区 33 , 即所述的模穴 31的周缘界线 32， 如此可使射 出成型的塑质薄壳件 20在外缘端的凸缘 22处的外表膜 10更形密着且平整， 因 此当凸缘 22被当作毛边切除后， 即可增进塑质薄壳件复合体 1完成品的周缘边 的外相品质。
凭借本发明的外表膜 10的设计， 使整片膜可直接置入模具内以进行塑质薄 壳件 20的射出成型作业， 且所述的外表膜 10又可对射出料 20a的射出压力以 及温度产生分散作用来避免因射出料 20a的射出压力以及温度而破坏所述的外 饰层 11的完整性， 使所述的外饰层 11可选择较多种不同的材质， 例如： 选用 一布料层其可由天然纤维或人造纤维构成， 或一合成皮革层由 PU (聚氨酯， Polyurethane ) 、 PVC (聚氯乙烯） 或 PU与 PVC合成皮构成， 且均可利用塑料 射出成型工艺来制成一具良好品质的塑质薄壳件复合体 1 ,故可达成制程简化的 目的。
在本发明外表膜 10的上述应用中， 所述的塑质薄壳件 20的射出料 20a相 对可选择较多种不同的塑料， 例如： ABS (丙烯腈-苯乙浠-丁二烯树脂） 、 PC (聚碳酸酯， Polycarbonate resin ) 、 Acrylic resin (压克力树脂 /丙烯酸树脂） 、 Nylon (尼龙 /聚酰胺树脂）等； 又所述的射出料 20a在射出成型时的压力以及温 度分别为： ABS的射出压力 80kg/mm2， 射出温度 200° C; PC的射出压力 120kg/mm2 , 射出温度 260° C; Acrylic resin的射出压力 100kg/mm2， 射出温 度 240。 C; 以及 Nylon (尼龙 /聚酰胺树脂） 的射出压力 80kg/mm2， 射出温度 260。 C; 其中所述的塑质薄壳件 20凭借射出成型时射出料 20a的射出压力以及 温度， 即可与所述的外表膜 10的内粘着层 13热熔结合成一体， 并同时迫使所 述的内粘着层 13， 厚度约 40-60 μπι, 的部分厚度约 10-20%, 即 4-12μιη， 得渗 透至所述的中间吸附隔热层 12中既有的孔隙中。
另， 本发明的外表膜 10也可应用于塑料押塑成型领域， 其中所述的外表膜 10可设在一押塑成型模具的模穴内， 再利用塑料押塑成型工艺而在所述的外表 膜 10的内粘着层 13上押塑成型一塑质薄壳件， 以形成一连续式的一体化复合 体； 由于塑料押塑成型工艺与塑料射出成型工艺类似， 故在此不再赘述。
