injection molding parts parts and mold cavity versus 似但却 is mold cavity 形状 扭曲版本. can can issues causes: （1） bending is is injection molding parts parts inner has more internal force. （2） injection molding parts mold filling speed degree slow. （3） mold cavity inner plastics 不足. （4） plastics temperature degree low or 不一致. （5） injection molding parts parts in ejection hot. （6） cooling or 动, temperature degree 不一致. （7） injection molding parts parts structure combined 理（如 add strong/high in in 一面, versus relatively 远）. remedy methods: （1） reduce injection molding parts pressure. （2） decrease/reduce screw toward front time. （3） increase cycle time （ especially is cooling time ）. from injection molding parts mold inner （ especially is relatively thick injection molding parts parts ） ejection rear 立即浸入 temperature water in （38℃） make injection molding parts parts slow slow cooling. （4） increase injection molding parts speed degree. （5） increase plastics temperature degree. （6） use cooling equipment. （7）适当 increase cooling time or improvement cooling conditions, can can ensure 动, mold temperature 一致. （8） according to 实际情况 in 允许 情况 lower improvement plastics parts structure.
