摘要
浇口直接影响注塑制品的外观、变形、成型收缩率及强度,如果选用不当,容易使注塑制品产生缺料、熔接痕、缩孔、浇口白斑、翘曲、变脆及降解等缺陷。根据注塑制品的不同特点,探讨了11种浇口形式的优缺点,进一步阐述了选用浇口类型与位置的方法及原则。
Gate directly influences appearance, deformation, molding constringency rate and strength of injection-moldedparts. Disfigurements such as material shortage, weld mark, shrinkage, gate-white-flecks, warpage, briekle, degradation, etc. will come into being in injection-molded-parts unless correct choice of gate. Based on the characteristics of injection-molded-parts, advanta- ges and disadvantages of eleven kinds of gates are discussed, and methods and principles of choice of gate style and gate location are expatiated.
