Pressure Gap
Hello everyone,
Please I need your help to understand the outputs, that our ARBURG machine gives. We have a difference of 200bar between the maximum injection pressure and the switch-over pressure (commutation pressure). My questions are:
Is that normal to have this difference? if is it not ==> what are the causes of this variation? especially in the switch-over pressure because it is the one that has a minimum value (700bar).
Note1: I remarque that most of our machines have approximately the same value in maximum injection pressure and switch-over pressure.
Note2: Injection stroke: 55 mm
Switch-over point: 15.7
Anyone can help me, I will appreciate it.
Thanks in advance.
