material tube/pipe temperature degree setting precautions: 1, is is make 滞留于 material tube/pipe and 螺 杆 inner cold hard resin melt, screw 之转动. 2, temperature degree = material tube/pipe temperature degree + machine hot can therefore material tube/pipe temperature degree setting ratio material can temperature degree need low. 3, material tube/pipe temperature degree setting usually separation is 4 段 control (large machine more more), most good can combined screw material 段, pressure shrink and amount 段, another again add upper nozzle separation to different temperature degree setting control, due to temperature degree is for conditions, material tube/pipe temperature degree is versus for. therefore according to material 流 状况 setting material tube/pipe temperature degree.
