料筒温度 喂料区 50~70℃(70℃)
区1 240~260℃(250℃)
区2 240~260℃(250℃)
区3 250~290℃(270℃)
区4 250~290℃(270℃)
区5 250~290℃(270℃)
喷嘴 250~290℃(270℃)
括号内的温度建议作为基本设定值,行程利用率为35%和65%,模件流长与壁厚之比为50:1到100:1
熔料温度 270~280℃
料筒恒温 220℃
模具温度 120~140℃
注射压力 薄截面制品可达160MPa(1600bar)
保压压力 大约注射压力的50%~70%以避免产生缩壁;按需选择保压时间;太长的保压时间易造成内应力,特别是对非晶体树脂,会使产品的抗冲击性降低
背压 5~10MPa(50~100bar),避免产生摩擦热
注射速度 因为高固化率和结晶率故需采用高速;避免在注射过程中熔料冷却和凝结;模内保持良好的通气性是很重要的,否则裹入的空气易使流道末端产生焦化
螺杆转速 最大螺杆转速折合线速度为0.5m/s
计量行程 (0.5~3.5)D,因为熔料对过热和在料筒内残留时间过长很敏感;残留时间不应超过5min
残料量 2~5mm,取决于计量行程和螺杆直径
预烘干 在120℃时烘干4h
