1) 对注塑成型参数的重复精度(再现性)要求高,宜采用多级注射反馈控制:
1) high accuracy (reproducibility) requirement for injection molding parameters. Multi stage injection feedback control should be adopted.
a.多级位置控制;
A. multilevel position control;
b.多级速度控制;
B. multistage speed control;
c.多级保压控制;
C. multistage pressure protection control;
d.多级背压控制;
D. multistage back pressure control;
e.多级螺杆转速控制。
E. multistage screw speed control.
位移传感器的精度要求达到0.1mm,这样可以严格控制计量行程、注射行程以及余料垫的厚度(射出监控点),保证每次注射量准确,提高制品成型泥杆 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修  托辊生产线精度。料筒及喷嘴温度控制要精确,升温时超调量要小,温度的波动要小。精密注塑应采用PID控制,使温度精确度在±0.5℃之间为宜。    
The precision of the displacement sensor is required to reach 0.1mm, which can strictly control the metering stroke, the injection stroke and the thickness of the residual cushion (shooting out the monitoring point), so as to ensure the accuracy of each injection and improve the molding precision of the products. The temperature control of the barrel and nozzle should be precise. When the temperature rises, the overshoot is small and the temperature fluctuation is small. Precision injection molding should be controlled by PID, so that the accuracy of temperature should be between 0.5 and C. Such
