Effect of Mechanical Processing on Intrinsic Stress and its Distribution in Polycarbonate Screw Cap

摘要：

　　The polycarbonate (PC) screw cap part had cracking problem during storage, which mechanism needed to be studied.The effect of mechanical processing on the intrinsic stress and its distribution in PC screw cap part was investigated in the paper.The analytical results indicated that the round pieces cut from polycarbonate bar had certain intrinsic stress residue from processing course, which decreased obviously after de-stress heat treatment.Mechanical processing also led to obviously increased intrinsic stress in screw cap part, which could be decreased obviously by another de-stress heat treatment.But the heat treatment increased the aging degree and cracking probability for polycarbonate screw cap part, and was not suggested to carry out on screw cap.Based on the experimental results, some suggestions were also given to lower the intrinsic stress in screw cap.
