优化加长喷嘴的加热与温度控制

Optimizing the heating and temperature control of extended nozzle

普通的加长喷嘴的加热与温度控制,不能满足部分工程塑料的成型特点,对于一些熔融温度范围小,热稳定性差的塑料,需要一个更精准的喷嘴加热与温度控制。但过度的精准温度控制,又会使相邻的二个喷嘴上的热电偶互相干涉,从而导致温度显示错误。本文介绍,怎样优化加长喷嘴的加热与温度控制。

The heating and temperature control of ordinary extended nozzle can not meet the molding characteristics of some engineering plastics.For some plastics with small melting temperature range and poor thermal stability,a more accurate nozzle heating and temperature control is needed.However,excessive accurate temperature control will make the thermocouples on the two adjacent nozzles interfere with each other,resulting in wrong temperature display.This paper introduces how to optimize the heating and temperature control of extended nozzle.
