Working principle
The injection molding machine pushes the plastic particles forward through the rotation of the screw, and heated and melted in a heating cylinder. When the plastic reaches a certain molten state, The injection device of the injection molding machine injects molten plastic into the mold cavity at high pressure. during the injection, The movable mold and the fixed mold of the mold are tightly closed, Provide sufficient clamping force, Prevent plastic spillage.
The mold is mainly composed of two parts: the movable mold and the fixed mold.
