ABS/PC(注塑工艺)

料筒量度 喂料区 50～70℃（70℃）

区1 230～250℃（250℃）

区2 250～260℃（260℃）

区3 250～270℃（265℃）

区4 250～270℃（265℃）

区5 250～270℃（265℃）

喷嘴 250～270℃（270℃）

括号内的量度建议作为根本设定值，行程利用率为35％和65％，模件流长与壁厚之比为50：1到100：1

熔料量度 260～270℃

料筒恒温 200℃

模具量度 70～90℃

打针压力 80～150MPa（800～1500bar）

保压压力 打针压力的40％～50％以防止制品出现缩壁；为了使制品的内应力小化，保压压力应该尽可能性安装低

背压 只要5～10MPa（50～100bar），防止发生摩擦热

打针速度 中等打针速度，将摩擦热降至小；多级打针；对有些制品建议采用从慢到快

螺杆转速 螺杆转速折合线速度为4.0m/s

计量行程（1.0～3.0）D，因为熔料对过热和在料筒内残留时期过长很敏感；电动喷雾器残留时期不应超过6min，在热流道中的滞留时期也应尽可能性小残料量 2～5mm，起源于计量行程和螺杆直径

Huayun Plastic Company pre-drying at 80 °C under the measurement of drying 4H recovery, can participate in 20% of the return material, as long as the material does not appear thermal degradation and has been properly pre-drying, such as for the strength requirements of the product is better shrinkage, even ISOTROPIC, 0.5% ~ 0.7% ; for glass fiber reinforced, 0.2% ~ 0.4% gate system, any kind of ordinary gate can be used; there are hot runner at the gate, the measurement must be closed loop control machine downtime, closed heating, the Electric Sprayer operates the machine like an extruder to clean the cylinder, the diameter of the standard screw is 50mm; for the large screw, the reduced size and the short measuring section are adopted; the Stop Ring is directed to the nozzle.
