Conical twin screw extruder Important functions:
1. Material plasticization: It can effectively heat and plasticize plastic raw materials to achieve a state suitable for extrusion molding.
2. Mixing and homogenization: plastic materials with different components can be fully mixed to ensure the uniform distribution of materials.
3. Extrusion molding: the plasticized and mixed materials are pushed through the rotation of the screw, and extrusion into various shapes of products through the head mold, such as pipes, plates, profiles, etc.
Conical twin screw extruder features
1. Excellent plasticizing performance
Due to the conical structure, the compression ratio of the screw gradually increases, which is conducive to the plasticization and melting of the material and improve the quality of the product.
It can better adapt to the processing requirements of different plastics, especially for heat-sensitive plastics and plastics that are difficult to plasticize.
2. Higher output
The design of the twin-screw increases the conveying capacity of the material, thus improving the production efficiency.
It can be operated at higher rotational speeds to achieve greater extrusion volume.
3. Good mixing effect
The mutual meshing and rotation of the two screws make the material experience complex flow and shear during the extrusion process to achieve a more uniform mixing.
4. Self-cleaning performance
The special structure and relative movement of the screw can reduce the retention and accumulation of materials on the screw, reducing the risk of material residue and cross-contamination.
5. You're adaptable
Can process a variety of plastic materials, including PVC, PE, PP, etc.
Can adapt to different formulations and process requirements, by adjusting screw speed, temperature and other parameters to meet the production needs.
For example, in the production of PVC pipes, conical twin-screw extruders can excellently complete the plasticization and extrusion molding of materials to produce high-quality pipes. In the production of complex plastic profiles, its good mixing effect and adaptability make it possible to precisely control the performance and shape of the product.
In short, the conical twin-screw extruder plays an important role in the plastic processing industry with its unique functions and characteristics.
