Customized nitride cylinder screws injection bimetallic single screw barrel for injection molding machine
The function of the screw of the injection molding machine is to complete the conveying, compacting, melting, stirring and pressurizing of the plastic through the rotation of the screw in the barrel. The structure of the barrel of the injection molding machine is a round tube with a blanking opening in the middle. The barrel contains the screw, which rotates inside the barrel
The barrel screw of the injection molding machine is an important part of the injection molding machine, which has the advantages of high yield, low unit consumption, strong plasticizing capacity, wear resistance, corrosion resistance and long service life.
