injection pressure set on the injection molding machine controller

[Ulynovsk]

Hello everybody!!

Gentlemen please tell me, in my injection molding machine firm Bole (China) injection speed is set in%:
1. How to convert percentages into volumetric or linear injection rates?
2. The injection molding machine is designed for the maximum injection pressure (hydraulic system pressure) of 140 MPa according to the passport. I limit the pressure on the control controller to 120 MPa, why does the manometer show 1200 psi or 8 MPa?
3. If the pressure controller is set at a pressure less than the injection speed (in%), for example: 1-stage 20 MPa; 60% injection rate - is this correct?(photo 1)
4. On the photo 2 the handle of the temperature regulator nozzle. How do you set the temperature on the nozzle?
