What is Cone twin-screw?

Structure Characteristics

Cone twin-screw has different diameters at both ends, with a larger diameter at the feeding section and a smaller diameter at the homogenization section, gradually transitioning in the middle. This design ensures a more uniform plasticization process of the material inside the screw, particularly suitable for processing PVC and other thermoplastic plastics. Compared to traditional parallel twin screws, Cone twin-screw has a more optimized structure, better adapting to the processing requirements of different materials.

Working Principle

The two conical screws mesh with each other and rotate in opposite directions inside the barrel. The material undergoes intense stirring and shearing, achieving a high degree of plasticization and mixing effect. This working principle ensures a more uniform residence time of the material inside the screw, thereby improving product quality and production efficiency.

Application Fields

Cone twin-screw is widely used in the plastic processing industry, especially suitable for processing PVC and other thermoplastic plastics. Its unique design and working principle ensure a more uniform plasticization process of the material inside the screw, thereby improving product quality and production efficiency. In addition, Cone twin-screw can also be applied to other fields requiring high plasticization and mixing, such as rubber processing, food processing, etc.
