目的：解决薄壁塑件在注塑成形过程中出现的翘曲问题。方法采用moldflow软件对产品注塑成形过程进行了数值模拟分析，确定了补偿量，运用补偿法对模具进行了修正，补偿变形量。结果经过对模具的适当修正，薄壁塑件的翘曲量由原先的0．89 mm减少到0．29 mm，装配精度得到了很大改善。结论运用补偿法对塑件进行模具设计，使薄壁塑件的翘曲变形量大幅减少，尺寸精度满足使用要求，为生产实践提供了可靠依据。

To solve the warpage of thin-wall plastic parts occurring in the injection molding process.Injection molding process was analyzed by numerical simulation using Moldflow software, from which the amount of compensation was deter-mined.The mould was corrected by compensation method to compensate the deflection.After appropriate amendments to the mould, the warpage amount of the thin-wall plastic parts was decreased to 0.29 mm from the original amount of 0.89 mm, which greatly improved the assembly accuracy.The warpage amount of the thin-wall plastic parts was greatly de-creased and the dimensional accuracy met the operating requirement when the compensation method was used in mould de-sign for plastic parts, which provides a reliable basis for the production practice.
