注塑制品翘曲变形的影响因素及对策

Factors affecting the warpage of injection molded parts and Countermeasures

翘曲变形是注塑制品常见的成型缺陷,它直接影响注塑制品的外观质量和使用性能。基于翘曲变形的产生机理和多年的实践经验,作者从塑料性能、塑件结构、模具结构、成型工艺参数、塑件脱模后处理情况等方面对翘曲变形的影响因素进行了较详尽的分析,并给出了相应的对策。

the defects of injection molding warpage is common, it directly affects the appearance quality and the performance of injection molding products. Warping deformation mechanism and many years of practical experience on the basis of the author, from the performance, the structure of plastic parts, plastic mold structure, molding process parameters of plastic parts, demoulding after treatment and other aspects of the factors affecting the warpage is analyzed in detail, and gives the corresponding countermeasures.
