常见注塑成型缺陷及解决办法

由于塑料制品使用时外观要求高、抗冲击韧件要好,而注塑成型加工过程是一个涉及多方面因素的复杂加工流程,在生产过程中会出现产品缺陷,本文分析了生产塑料件时常见缺陷产生的原因,并从成型工艺条件(温度、压力、时间、注射速度等)的调整、模具结构合理性的修改、原料使用前处理等方面提出了解决问题的措施与对策。

Common injection molding defects and Solutions

Due to the use of plastic products,the appearance of high demand,the impact toughness is better,and the injection molding process is a complex process involving many factors in the production process,will appeared in the process of product defects,this paper analyses the production of plastic parts causes of common defects,and from the molding technological conditions(temperature,pressure,time the injection speed,etc.),the rationality of structure adjustment of mould modification,raw material use before treatment and other aspects of proposed measures to solve the problem and countermeasure.
