Conical Twin Screw Barrel

The Conical Twin Screw Barrel is a type of extrusion screw barrel that is widely used in the plastic processing industry. It is specifically designed for applications that require high output rates and excellent mixing capabilities.

This type of screw barrel features a unique conical design, with two screws placed parallel to each other within a cylindrical barrel. The screws have a tapered shape, with a smaller diameter at the feeding end and gradually increasing in diameter towards the discharge end. This design allows for efficient material conveying and improved melt homogeneity.

The Conical Twin Screw Barrel is known for its versatility and ability to process a wide range of materials, including PVC, PE, PP, and other thermoplastics. It is particularly suitable for applications that require high torque and high shear, such as pipe extrusion, profile extrusion, and sheet extrusion.

One of the key advantages of the Conical Twin Screw Barrel is its excellent self-cleaning properties. The conical shape of the screws creates a natural wiping action, which helps to remove any residue or buildup from the barrel walls. This results in reduced downtime for cleaning and maintenance, as well as improved product quality.

Furthermore, the Conical Twin Screw Barrel offers enhanced heat transfer capabilities due to its increased surface area. This allows for efficient melting and mixing of the materials, resulting in a more uniform melt temperature and improved product quality.

In conclusion, the Conical Twin Screw Barrel is a highly efficient and versatile extrusion screw barrel that is widely used in the plastic processing industry. Its conical design, self-cleaning properties, and excellent heat transfer capabilities make it an ideal choice for applications that require high output rates and excellent mixing capabilities.
