    • PROBLEM TO BE SOLVED: To provide an insert molding free from a thermoplastic resin film-like body having a deformation such as slackening and bulging with respect to a thermoplastic resin molding, and also to provide a manufacturing method therefor. SOLUTION: This insert molding 1 comprises a thermoplastic resin molding 2; and a thermoplastic resin film-like body 4 formed integrally with the molding 2 by insert molding. The film-like body 4 is heated to a temperature of bringing a secondary shrinkage rate thereof into a shrinkage rate or more of a thermoplastic resin of the molding 2, when insert-molded. In this manufacturing method for the insert molding 1, the thermoplastic resin film-like body 4 is arranged in a recess 14 of a female mold 12, a cavity 16 of a shape to form the molding 2 is formed on one face of the film-like body 4, the film-like body 4 is heated at the temperature of bringing the secondary shrinkage rate thereof into the shrinkage rate or more of the thermoplastic resin forming the molding 2, in the cavity 16, and the thermoplastic resin is injection-molded under this condition.

    • 要解决的问题:提供一种没有热塑性树脂膜状体的插入成型体,其具有相对于热塑性树脂成形体的松弛和膨胀的变形,并且还提供其制造方法。

      解决方案:该嵌入成型体1包括热塑性树脂模制件2; 以及通过嵌件成型与成型体2一体形成的热塑性树脂膜状体4。 当插入成型时,将薄膜状体4加热到使其二次收缩率成为模制品2的热塑性树脂的收缩率或更多的温度。 在这种插入成型用的制造方法1中,热塑性树脂膜状体4配置在阴模12的凹部14中,形成成型体2的形状的空腔16形成在膜 - 在空腔16中,在使其二次收缩率成为形成模制品2的热塑性树脂的收缩率或更多的温度下,将膜状体4加热,并将热塑性树脂注射成型 在这种情况下。 版权所有(C)2009,JPO&INPIT
