A hydraulic injection molding machine uses pressurized fluid from a pump to generate the force needed to clamp molds shut and inject molten plastic into a cavity. It is a strong, heavy-duty manufacturing tool best suited for high-tonnage production and large, thick-walled parts.
Key Components
Clamping Unit: Uses hydraulic cylinders or toggles to hold the mold halves tightly together under massive pressure.
Injection Unit: Features a reciprocating screw and hydraulic motor to melt, mix, and push the liquid plastic forward.
Hydraulic System: Includes pumps, valves, hoses, and fluid reservoirs that direct power to move parts of the machine.
Control Panel: Manages temperature, injection speed, pressure levels, and cycle timing.
