邻苯二甲酸二烯丙酯精密注塑

摘要

The granular thermosetting plastics are made of diallyl phthalate (DAP) resin milled with fiberglass and inorganic filler. The electronic parts which have high shape accuracy and copper inserts are made of the granular thermosetting plastics by injection molding. The problems which occur at the process of injection molding electronic parts are analyzed. theprecise injection molding technique with injection-compression is put forward to solve the problem.%利用邻苯二甲酸二烯丙酯(DAP)添加玻璃纤维与无机填料等混炼而成的粒状热固性塑料,注塑形状精度要求高、有铜质嵌件的电子零件,针对其注塑过程中所出现的工艺问题进行分析,并提出其注塑-压缩的精密注塑解决方法.
