注塑件翘曲问题分析与对策

Analysis and countermeasure to warpage of injection parts

塑件翘曲指的是注塑产品出现扭曲或者弯曲现象，实际形状与设计型腔的形状产生偏差，令产品的尺寸精度下降，直接影响产品的可装配性，是注塑件的常见缺陷。因为该产品质量问题成因复杂，常常引发产品设计师、模具设计师和成型师三者之间的协调矛盾。准确分析问题的主要成因有助于提出有效的解决办法。

Injection parts warping means to twisting or bending of injection parts,real shape deviation from desiged shape,lead to decreasing of production＇dimension precision,direct impact on production＇s assembling ability,is a normal defect of injection parts. Because the complex origin of this problem,it often caused confliction among product designer,mold designer and shaping designer. Analysis on this problem can provide effective solutions.
