摘要
分析了注射成型过程中顶杆印迹缺陷包括顶凸、顶白、顶穿和顶杆处亮斑等的产生机理,以聚丙烯电器设备外壳、汽车仪表板和汽车内饰件生产中出现的顶杆印迹为例,从材料、设备、模具和注塑工艺方面提出一些解决措施。
The mechanisms of ejector marks such as ejector bumps, ejector whitening, ejector breaks, ejector lightening,etc. accured in injection molding were analyzed. Some advices were list on material, injection machine, mould design and process settings adjustment with polypropylene crust of electric equipment, fascia and inner parts as examples.
