Nitriding Screw and Barrel for Rubber
The barrel and the screw work together, the barrel contains the screw, and the screw rotates in the barrel. When the screw rotates and pushes the plastic to move forward in the barrel, the outside of the barrel heats and transfers heat to the plastic in the barrel. In addition, the volume of the screw on the screw is gradually reduced, so that the plastic in the screw groove is squeezed, turned and cut. After the action of various forces such as cutting, it is uniformly mixed and plasticized. As it moves to the front of the barrel, it gradually melts into a viscous fluid state, completing the plasticization of the plastic.
