Product Specification Clamping Part
The mechanism of the injection molding process begins with the raw material in the hopper down to enter the cavity in the screw thread. Screw will move to bring the barrels to the plastic granules to melt the plastic granules. The next step, the mold is closed and the screw is driven forward by a piston to push the molten plastic from the screw chamber through a nozzle into the mold. The molten plastic has been injected experienced hardening due to heat energy absorbed by the water-cooled mold walls. After the cooling process and product rigidity enough then screw moves backward to make the filling barrel. At that time, the clamping unit will move to open the mold. Products issued by the ejector. After that, the mold is ready to be injected back. The following figure shows the mechanism of injection molding.
