Detailed Product Description

Bimetallic Parallel Twin Screw and Barrel for Plastic Extruder for PVC Pipe UPVC Profile Plastic Recycling Plastic Sheet

 

1 . Description

The Bimetallic Parallel Twin Screw and Barrel for Plastic Extruder is a type of extruder screw and barrel that is designed for processing a variety of plastic materials, including PVC (polyvinyl chloride) and UPVC (unplasticized polyvinyl chloride) for various applications, such as pipe, profile, sheet, and plastic recycling.

The screw and barrel are made of two different materials. The base material is typically high-quality alloy steel, while the outer layer is made of a wear-resistant material, such as tungsten carbide or a nickel-based alloy. This bimetallic construction provides the screw and barrel with high wear resistance and durability, which is important for processing abrasive plastic materials, such as PVC.

The Parallel Twin Screw and Barrel design allows for efficient and consistent plastic processing. The twin screw design provides better mixing and melting of the plastic material, resulting in a more uniform and consistent product. The tight screw pitch and high screw speed generate high shear forces, which are necessary for melting and processing PVC and UPVC materials.

The Bimetallic Parallel Twin Screw and Barrel for Plastic Extruder is also designed for easy cleaning and maintenance. It has a self-cleaning design that helps to prevent material buildup and reduces the need for frequent cleaning. The screw and barrel can be easily removed and replaced when necessary.

Overall, the Bimetallic Parallel Twin Screw and Barrel for Plastic Extruder is a high-quality and reliable component for plastic extrusion machinery that ensures consistent and efficient processing of PVC and UPVC materials for various applications. Its wear-resistant bimetallic construction and efficient design make it a popular choice for plastic extrusion manufacturers who require high-quality products with high production rates and long service life.

2 . Comparsion of the output (LDPE)

Pressure is generated if resin passes over the barrier, forcing any air in the melted resin back to the feed side and effectively preventing the intrusion of air bubbles on the sub flight side. This is highly effective with resins that generate bubbles such as PS, PA, PET and EVOH.

Bimetallic Treatment of Screw

The bimetallic screw for extruder twin screw is a kind of screw spray welding a 2~3mm-thick alloy coat on the screw flight of output area for the screw . The Bimetallic treatment has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided screw.
