Semi Automatic Moulding Machines

In a semi-automatic type, the clamping cylinder and the injection cylinder are operated by levers which is connected the pneumatic or hydraulic cylinder. In automatic type, the cylinder is actuated automatically to set times.The working principle of the injection molding machine is similar to the syringe used for injection. It uses the thrust of the screw (or plunger) to inject the plasticized plastic in the molten state (that is, the viscous fluid state) into the closed mold cavity.
