Hydraulic Power Units (HPU)
The hydraulic power unit provides the fluid power source and controls required for operating the casting cylinder and mold table tilt system. This state-of-the-art hydraulic control system provides the consistently smooth and accurate platen descent required for successful casting with today’s advanced technologies.
Foshan Huitai manufactures each hydraulic power unit to specifically complement the Casting Machine and related equipment that it will power. The hydraulic system consists of a hydraulic fluid reservoir and hydraulic pumps with drive motors. Logic check valves and pilot control valves mounted in a single hydraulic control manifold are used to control the hydraulic system.
With this design there is no differential pressure that could cause the platen to surge up or drop down, and in the event that metal flow is lost, the cast can be terminated normally without causing damage to the mold table.
A separate auxiliary hydraulic circuit provides hydraulic power to the mold table tilt mechanism and other hydraulic actuators that may be part of the system.
