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

The metering stroke (1.0 ~ 3.0) D of Huayun Plastics company, because the melt material is very sensitive to overheating and the residual period in the barrel is too long; the residual period of the electric sprayer should not exceed 6 minutes, the retention time in the hot runner should be as small as possible 2 ~ 5 mm, which originates from the metering stroke and the recovery of the screw diameter after pre-drying at 80 °C for 4 hours, and can take part in the 20% recycle, as long as the material has not undergone thermal degradation and has been properly predried, it is better to have an ISOTROPIC shrinkage of 0.5% ~ 0.7% for products requiring less strength, and 0.2% ~ 0.4% for glass fibre reinforced gating systems, any kind of ordinary gate can be used; there is a hot runner at the gate, the measurement must be closed loop to control the machine shutdown period, shut down heating, electric sprayer operates the machine to clean the drum and barrel apparatus as if operating an extruder, the diameter of the standard screw is 50mm; for the large diameter screw, the geometric size of the smaller and shorter measuring section is adopted; the Stop Ring and the through nozzle are adopted.
