Dec 27, 2016 · From the machine’s controller we find that the maximum hydraulic pressure we can set for the injection cylinder is 2250 psi. So: Ri = 26,500 psi/2250 psi = 11.78:1. To calculate the plastic pressure for backpressure during screw rotation with a machine setting of 75 psi hydraulic, multiply the hydraulic pressure times the intensification ...

With the screw completely forward, increase the backpressure to the maximum level. After ASACLEAN begins coming from the nozzle, increase the screw speed to the maximum safe level. Drop the backpressure after the ASACLEAN coming from the nozzle is almost clean. Retract the screw and perform short, high-velocity injection shots.
