摘　　要：讨论注塑制品内应力的分类及产生机理,并针对碱性蓄电池壳盖所用的几种热塑性塑料如(乙烯/丙烯)共聚物、(丙烯腈/丁二烯/苯乙烯)共聚物、尼龙、(丙烯腈/苯乙烯)共聚物、(甲基丙烯酸酯/丁二烯/苯乙烯)共聚物具体分析了材料、成型工艺、模具设计对制品内应力的影响,给出了减小内应力的控制方法,提出了制品内应力的检验及消除方法。The classification of internal stress in injection products and its mechanism of the generation are discussed. The effects of materials, forming techniques, design of the mould are fully analyzed according to the thermoplastics such as E P, ABS, PA, AS and MBS which are used for producing shell and cover of alkaline storage battery. The method of measurement and decreasing or clearing off the internal stress in products are pointed out.
