1.影響產品的尺寸精度:根據產品的尺寸制造模具的尺寸。如果尺寸減小很多并且變化很多,則獲得的產品難以匹配理想的幾何尺寸,并且難以滿足使用要求。特別是對于某些需要精確尺寸的精密機械零件,例如齒輪,蝸輪等,它們需要很高的協調精度,在注塑成型后無需進一步加工即可投入使用。如果不需要尺寸,將會給相關的傳動帶來困難。甚至難以配對且無法使用。對于某些箱型零件,例如泵體,儀表箱等,必須在其上安裝許多其他零件,并且由于產品的收縮和尺寸變化,無法按照預定要求安裝,使其成為廢品。
2.使塑料零件變形和破裂。增強的尼龍熔體通過噴嘴在高壓下注入模腔。增強尼龍熔體進入模腔的特性使其在成型過程中沿不同方向收縮。沿流動方向的收縮大且強度高,而沿垂直于流動方向的收縮小且強度低。另外,由于增強尼龍塑料部件的各個部分在成型過程中的不均勻密度和填充物分布,各個部件的收縮不均勻等,因此增強尼龍塑料部件的性能是各向異性的,并且收縮取向還會導致塑料零件各個部分的收縮不一致。這種不均勻的收縮將引起更大的質量問題,例如翹曲和變形,甚至裂紋和其他缺陷。具有這種質量缺陷的塑料零件很難使用。 。以上文獻若需轉載請備注出處:PBT樹脂 //shanglikaiguan.cn/
