PX-Φ50~200 ?Equi-diameter ratio: L/D=18~25, the screw compression ratio is designed according to different raw materials and different products. The redirectional parallel twin screw can process PVC pipes, re-shaped materials, plates (sheets), modified and soft and hard PVC granulation.
Product Advantages:
The flat twin screw is designed with controllable tightening, which effectively avoids elastic deformation problems in traditional screw transmission systems, thereby achieving higher precision motion control. This feature makes our products more stable and reliable during material mixing and conveying, and improves production efficiency and product quality. In terms of screw surface treatment, we adopt advanced dual alloy spray welding technology, which is a surface treatment process that combines high hardness and good wear resistance. By precisely controlling the spray welding parameters, the dual alloy layer is closely combined with the substrate material to form a solid wear-resistant protective layer. This protective layer can not only effectively resist the wear caused by materials when sliding on the screw surface, but also resist erosion from harsh working conditions such as high temperature and corrosion, thereby greatly extending the service life of the screw. Customers can reduce downtime and costs due to equipment replacement and maintenance, further improving productivity and economic benefits. The design of parallel twin screws also fully considers torque load-bearing capacity and energy consumption efficiency. The unique structure allows the screw to maintain a stable operating state when withstanding large torque, and the optimized transmission efficiency significantly reduces energy consumption. This high load-bearing and low energy consumption can save customers a lot of energy costs during long-term use and improve the sustainability of overall operations.
