【Abstract】 Injection molding defects, such as underfeeding, burning, gas mark and silver streak etc., can be found mainly because of bad mold venting. This paper studied the air state changing in a mold cavity during mold filling, analysed results of calculation, explainded the reasons for producing injection defects,and finally proposed the principles of choosing parameters of mold venting slot.更多还原
