Rubber Extruder Machine Screw Barrel

Rubber extruder machine screw barrels are essential components in rubber extrusion equipment, designed to melt, mix, and extrude raw rubber compounds through a die to create continuous profiles, tubing, seals, and other rubber products. These screw barrels are engineered to withstand high temperatures, pressures, and the abrasive nature of rubber materials used in extrusion processes.

Specification:

Pin screw, barrel specifications:Φ20mm~Φ650mm

Cold and hot feeding screw specifications: Φ20mm~Φ650mm

L/D ratio:12-18

The compression ratio of screws can be designed according to different products and ingredients.

The use of pins can make the mechanical processing of rubber extruder more effective, and it can shear and stir the flow of rubber material, which is a very efficient and energy saving processing process. The screw produced by our company has a unique geometric structure, which enables to complete difficult plasticizing, mixing and extrusion processing. The common screw is made of 38CrM0AIA material with nitriding treatment on its surface. There is also alloy screw with better use effect and longer service life, its surface sprayed with special alloy powder which is of wear resistance and high corrosion resistance.

Our Benefits

1. Precision Melt Control and Mixing

Injection molding machine screw barrels ensure precise melt control and thorough mixing of additives, colorants, and fillers into the polymer melt. This results in uniform melt quality and enhanced part aesthetics.

2. Extended Service Life and Durability

Our screw barrels are manufactured from high-quality materials, including nitrided steel, bimetallic alloys, and tungsten carbide coatings, to withstand abrasive wear and corrosion. This ensures extended service life and reduced maintenance downtime.

3. Optimized Injection Molding Parameters

By optimizing screw design and material selection, our screw barrels enhance injection molding parameters such as cycle time, shot size consistency, and part dimensional stability. This improves overall production efficiency and reduces scrap rates.

4. Customization Options

We offer customization options to meet specific customer requirements, including screw diameter, length-to-diameter ratio (L/D), flight geometry, material composition, and surface treatments. Our engineering expertise ensures that each injection molding machine screw barrel is optimized for maximum performance and reliability.
