It is very convenient to open twin screw extruder for checking abrasion level of elements and barrel inter-sheet, which achieves to change and repair items effectively and this avoids unnecessary consumption. If electric stoppage happens and the extruder stops heating, it need to re-heat and maintain the temperature before opening the extruder when electricity recovering.
Related to the heating process, we often heat the heating zone individually. When zone reach the temperature point, however, the die head does not reach the temperature( die head has thicker steel coating and larger square), and normal solution is maintaining the temperature., then start the machine after die head reaches the temperature point. This is the most effective we to decrease electric consumption.
