Alloy Spray-Welded Conical Twin-Screw Barrel

Product Feature And Application

1.Alloy spray-welded conical twin-screw barrel， with the longest life service, When working with high wear resistance, its lifespan is much longer than the nitrided parts. This significantly reduces downtime for replacement and enhances equipment utilization and production efficiency.

2.Double screw, with stable performance and high output.Ensured long-term consistency in the plasticization effect, extrusion volume and product quality.

3.Tungsten alloy spray welding can effectively handle the corrosive gases generated during the processing of materials such as PVC and those containing halogen flame retardants, and resist the combined damage caused by "corrosion + wear".

4.Bimetallic conical twin-screw Applied to hard and soft PVC, filled engineering plastics, industrial water pipes, WPC, PVC wood-plastic boards, foam boards, resin tiles, masterbatches and color masterbatches production.

Production Details

1. Plastic extruder conical twin screw with good performance:Good feed, gentle shearing, and pressure building

2. Alloy spray welding conical twin screw barrel. The rotational speeds of the two screws in the meshing area are opposite, enabling them to scrape against each other, effectively preventing material from getting stuck and decomposing.

3. Strong feeding capacity: The feeding section has a large diameter and a deep screw groove, which is highly suitable for the transportation of powdered materials (such as PVC powder), and is a significant advantage of the conical twin-screw design.

4. The inner wall of the barrel is also equipped with a nitrogenized steel or tungsten alloy liner, which has extremely high wear resistance and corrosion resistance, ensuring a long-term stable cooperation with the screw.
