PBT在熔融状态下流动性好，粘度低，仅次于尼龙，在成型易发生“流延”现象。PBT成型制品各向异性。PBT在高温下遇水易降解。2 PBT的注塑：选用螺杆式注塑机时。应考虑如下几点。①制品的用料量应控制在注塑机额定大注射量的30％～80％。不宜用大注塑机生产小制品。②应选用渐变型三段螺杆，长径比为15～20，压缩比为2.5～3.0。③应选用自锁式喷嘴，并带有加热控温装置。④在成型阻燃级PBT时，注塑机的有关部件应经防腐处理。

3 PBT制品与模具设计①制品的厚度不宜太厚，PBT对缺口很敏感，因此，制品的直角等过渡处应采用圆弧连接。②未改性PBT的成型收缩率较大，在1.7％～2.3％，模具要有一定的脱模斜度。③模具需要设排气孔或排气槽。④浇口的口径要大。⑤模具需设置控温装置。模具高温度不能超过100℃。⑥阻燃级PBT成型，模具表面要镀铬，以防腐。
