The application differences of Screw barrel for extrusion of sections in different plastic profiles and how to choose the appropriate configuration?

In the plastic processing industry, Screw barrel for extrusion of sections plays a crucial role, as its performance directly affects the quality and production efficiency of extruded products. There are significant differences in the requirements for screw barrels during the extrusion process for different types of plastic profiles, such as PVC pipes, PE boards, ABS profiles, etc.

The physical properties such as melting temperature, viscosity, and flowability of different plastics vary, which requires the screw barrel to fully consider these factors in its design. For example, PVC material is prone to thermal decomposition during extrusion, so the screw barrel needs to have a good cooling system and corrosion-resistant materials to ensure stable extrusion of PVC at high temperatures without degradation. In contrast, PE materials have better fluidity and thermal stability, and the design of screw barrels can focus more on improving melting efficiency and mixing uniformity.

Secondly, the shape, size, and wall thickness of the profile also affect the selection of the screw barrel. For the extrusion of complex shapes or thin-walled profiles, screw barrels require higher precision and stability to ensure the dimensional accuracy and surface quality of the extruded products. In addition, parameters such as screw speed, pitch, compression ratio, etc. also need to be optimized and adjusted according to the specific requirements of the profile.
When choosing the appropriate Screw barrel for extrusion of sections configuration, consumers should consider factors such as plastic type, profile requirements, production efficiency, and equipment cost comprehensively. It is recommended to have in-depth communication with professional plastic extrusion equipment manufacturers or suppliers to understand the performance characteristics and applicable scope of different configurations, in order to choose the most suitable screw barrel configuration for your production needs. Meanwhile, consumers can also refer to successful cases and expert opinions within the industry to obtain more comprehensive information and guidance.
