Clamp and Injection force/pressure and velocity controlled by means of Vickers and Rexroth proportional valves; Injection and clamp flow valves are equipped with closed-loop spool-position feedback feature on main spool; Injection valve is electronically closed-loop through control system and also has spool-position feedback on pilot spool which guarantees superior injection response and repeatability |
|
Hydraulic Circuit consists of a combination of multiple Vickers vane pumps for general machine functions and a variable volume pump dedicated to clamp force hold and eject/core functions |
|
Hydraulic Oil Filtration: 5-micron pressure and return line filters for continuous oil filtering; Filter alarm status is displayed on the machine control screen |
|
Oil Temperature Control: PID closed-loop system including oil warm-up sequence, with adjustable temperature set points and limits |
