Mar 05, 2020 · 2. Servomotor Hydraulic. Instead of an induction motor, servomotor hydraulic machines use servomotors coupled with a hydraulic gear pump. This means that the motor only spins when you need something to deliver oil to a hydraulic cylinder or hydraulic motor in order to perform one of the machine movements.

Understanding Intensification Ratio | Plastics Technology

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 ratio.

Forces and Calculations Are Key to Sizing Core Pull ...

Aug 05, 2020 · As some presses remove hydraulic pressure to core circuits during injection, the use of hydraulic cylinders without a heel block or preloading locking cylinder may not be possible. For presses that drop hydraulics, ensure locking cylinders maintain preload after locking without pressure or that an independent hydraulic source is available.
