THE NEW TECHNOLOGY OF FUSIBLE CORE INJECTION MOULDING
Author(s): 
Pages: 35-37
Year: Issue:  8
Journal: ENGINEERING PLASTICS APPLICATION

Keyword:  可熔型芯工艺过程温度控制时间控制;
Abstract: 阐述了用可熔型芯注射成型热固性塑料的工艺过程和原理、工艺控制要点.用低熔点合金制成可熔型芯替代注射模具中的抽芯部件,在升温固化制件的同时熔化可熔型芯,用熔芯代替抽芯取出制件.通过合理控制成型过程各阶段的温度和时间,将制件的热固化过程、可熔型芯的熔化与再浇铸过程结合在一起同时进行,既实现了无法抽芯的中空异形制件的整体成型,又简化了模具结构,同时充分利用了热能、降低了成本、提高了生产效率.
