The company specializes in producing various rubber screw barrels!
Products across: sealing rubber strip extrusion, rubber wire extrusion.
Rubber machine screw barrel price operating range:
1. Brand screw barrels: Haitian injection molding machine screw barrels, Zhenxiong injection molding machine screw barrels, etc .;
2. Screw barrels for various extruders: Customized screw barrel sets for sheet, pipe, and profile extruders;
3. Special screw barrels for various film blowing machines and rubber machines;
4. Special screw barrels for various injection molding materials: PA nylon material, PMMA acrylic material (plexiglass), EPS foam plastic
The aspect ratio of the screw is the ratio of the length L of the screw to the diameter D of the screw. The screw has a large length-to-diameter ratio, that is, the screw has a long working part, and the rubber material is plasticized and mixed uniformly. However, the length of the screw can easily cause scorching of the rubber compound, which makes the screw processing difficult and increases the extrusion power. The screw used for hot-feeding extruder is generally 4 to 6 times longer, and the screw used for cold-feeding extruder is generally 8-12 times longer.
