Barrel screw

The barrel screw is an important storage part of the injection molding machine. When the screw rotates and pushes the plastic material 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 turned over. It is quickly melted under the action of various forces such as shearing, and the different raw materials are uniformly mixed through the mixing and auxiliary teeth on the screw. As it moves to the front of the barrel, the air in the barrel is gradually squeezed out of the barrel, and the raw materials are melted. In a viscous fluid state, the plasticization of the plastic is completed. The normal cooperation of the barrel and the screw completes the change of the physical state of the raw material, and smoothly enters the mold for cooling and forming.
Our company distributes special screws for injection molding machines in Shanghai Jikang, Zhejiang Huaye, and Ningbo Tianxing, and supports customized reservations for special process screws for injection molding machines of various brands.
