SCREW AND BARREL FOR PLASTIC FILM SQUEEZING MACHINE
__________________
Product Details
SCREW BARREL for granulation machine/ Pelletizer. We have rich experience in pelleting screw barrel. We have developed a variety of new type of granulation machine/Pelleting screw barrel, with different screw designs, greatly improved the production output, and enhance the service life via continuous practice. The screw barrel can be used for materials like PP, PE, ABS, PET, PA, PMMA and all kinds of engineering plastics. We also water granulation type screw barrel, and design for film with new type high efficiency. The screw barrel adopts the special compulsory feeding design system with high efficiency and output which access to the user's praise.
