一、概述环氧树脂在硬化状态下,对各种金属和非金属表面具有较强的附着力,并且硬化时收缩小,聚合时不需要附加压力;同时,环氧树脂还具有相当硬度和一定韧性。因此,常用它来进行模具零件的胶合。例如:固定凸模、导柱和导套,以及成型复杂形状的卸料板,国外还常用来制作弯曲模和拉伸模。实践证明,使用 First, an overview Epoxy resin in the hardened state, a variety of metal and non-metallic surfaces with strong adhesion, and shrinkage when hardening is small, the polymerization does not require additional pressure; the same time, the epoxy resin has a considerable hardness and certain toughness. Therefore, it is often used to glue the mold parts. For example: fixed punch, guide post and guide sleeve, as well as forming a complex shape of the stripper, abroad also commonly used to produce bending die and drawing die. Practice has proved that use
