Injection molding machine screw barrel

- Jul 03, 2018 -

All of these procedures are accomplished by the rotation of the screw within the barrel. When the screw rotates, the plastic will produce friction and mutual movement between the inner wall of the barrel, the bottom surface of the groove, the rib advance surface and the plastic and plastic. The forward advancement of the plastic is the result of the combination of the motion, and the heat generated by the friction. It is also absorbed to increase the plastic temperature to melt the plastic. The structure of the screw will directly affect the extent of these effects. In order to improve the plasticizing quality, the screw can be designed as a separate screw, a barrier screw or a split screw.
