Screw structure: universal screw, mixing screw, barrier screw
Applicable materials: PE, PP, ABS, PET, PC, PA, and fillers

Are you facing the following issues:

1. The feeding process is not smooth, and the granular, crushed, and mixed materials cannot fully adapt
2. The temperature in a certain area of the barrel is out of control, causing the billet to sag, resulting in uneven longitudinal wall thickness and prolonging the forming cycle
3. Poor appearance quality of the billet accompanied by unstable extrusion pressure
4. Higher than energy consumption

Our advantages:

① We are committed to the structural design of screws – reducing specific energy consumption and improving production capacity
Solving the difficulty of feeding and controlling the temperature rise in the feeding section to eliminate gas impurities
Combining the geometric compression ratio of the screw with the compression ratio of the billet head, and setting reasonable shear dispersing elements, so as to make the material temperature controllable, the degree of material plasticization controllable, and the discharge end material flow more stable during the plasticization process
For high-yield screws, axial grooves are opened at the inlet of the barrel to control the number, depth, and width of grooves, thereby increasing the internal friction of the material and improving the pumping capacity of the screw.
② We select raw materials based on materials, customize production processes, and extend the service life of screws

The company undertakes the business of screw barrels with a length to diameter ratio of 1:24-1:32 for sizes ranging from 25 to 150
