Clamping Unit

The clamping unit uses a mechanism to open and close the mold, such as a toggle or hydraulic system. This mechanism is responsible for providing the necessary clamping force and ensuring precise alignment of the mold halves.

Hydraulic Unit

The hydraulic unit in an injection molding machine uses pressurized oil to power and control various functions such as clamping, injection, and movement of the machine.

Injection Unit

The Injection unit in an injection molding machine melts plastic material and injects it into the mold for proper filling and cooling to produce the final product, It is made up of a hopper, barrel, screw, nozzle, and a control system.

Control Unit

YongHua Cloud is a wireless communication system designed for high-response injection molding operations.
