PBT注塑工艺：
　　PBT的聚合工艺成熟、成本较低，成型加工容易。未改性PBT性能不佳，实际应用要对PBT进行改性，其中，玻璃纤维增强改性牌号占PBT的70％以上。
1、PBT的工艺特性
　　PBT具有明显的熔点，熔点为225～235℃，是结晶型材料，结晶度可达40％。PBT熔体的粘度受温度的影响不如剪切应力那么大，因此，在注塑中，注射压力对PBT熔体流动性影响是明显。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、原料准备
　　注塑前要进行干燥、要将水分含量控制在0.02％以下。采用热风循环干燥时，当温度为105℃、120℃或140℃时，所对应的时间不超过6h、4h、2h。料层厚度低于30mm。
3、注塑工艺参数
　　①注射温度 PBT的分解温度为280℃，所以实际生产中一般控制在240-260℃之间。②注射压力注射压力一般为50～100MPa。③注射速率 PBT冷却速度快，因此要采用较快的注射速率。④螺杆转速和背压 成型PBT的螺杆转速不宜超过80r/min，一般在25～60r/min之间。背压一般为注射压力的10％～15％。⑤模具温度 一般控制在70～80℃，各部位的温度差不超过10℃。⑥成型周期 一般情况下为15～60 s。
