摘　　要：手动螺丝是安装在台式电脑机箱内部的重要配件之一。但是这种产品却因为它的嵌入式的构造和塑胶件的注塑成型方式而出现内应力,导致放置几天后塑胶件出现开裂情况。观察和研究了塑胶件物料和手动螺丝结构后,使用退火的方式对其做去除内应力的改善。结果表明:通过超声波热压方式和冷压后在85℃的烘箱内烘烤4 h的方式,手动螺丝的内应力可以直接消除。同时对比两种方式,选出了最利于原有手动螺丝生产工艺的方式,并优化了其生产工艺过程。Thumb Screw is one important part in the computer chassis. Because of its embedded structure injection molding way for plastic part, it always crazes after some days. Observe research its plastic RM property structure of Thumb Screw, annealing action will be used to eliminate its inner stress. Final result is shown as follows： Use ultrasonic wave bonded way or put Thumb Screws in an oven with 85 ℃ for 4 h, its inner stress will be released completely. Meanwhile, comparing with the two methods, we can know the best way to optimize its original manufacturing technique process.
