Valve Gate system
The Osco
®
Valve Gate system from
D-M-E
represents the ultimate in part cosmetics,
knit line control and part quality over the widest spectrum of applications including
large, multi-gated parts and family molds with unbalanced flow.
This superiority can be attributed to the floating hydraulic cylinder/valve pin
assembly which provides positive indivual gate shut-off
The key to the system's operation is the method to open and close each gate. In the
opening cycle, delay timers activated by the machine's high-pressure clamp circuit
allow injection pressure to build. At a determined time, hydraulic cylinders retract
the valve piston/pin assembly at each gate, permitting material to flow into the mold
cavity at an increased velocity. Secondary individual timers positively close each
gate after the proper pre-set fill time, eliminating overpacking while allowing other
gates to remain open until their optimum fill time is reached.
Two nozzle styles are available: the Full-Body nozzle is suggested when a circular
nozzle mark is allowed, the Bodyless nozzle offers impeccable cosmetics, feeding
directly into the part.
