The benefits of increasing the aspect ratio of screws

1. Adequate screw pressure can improve the physical and mechanical properties of the product.

2. The material is well plasticized and the appearance quality of the product is good.

3. Increase extrusion volume by 20-40%. At the same time, the characteristic curve of screws with a large aspect ratio has a smaller slope, is flatter, and the extrusion amount is stable.

4. Beneficial for powder forming, such as PVC powder extrusion pipe. However, increasing the aspect ratio makes it difficult to manufacture the screw and assemble it with the barrel. Therefore, the aspect ratio cannot increase indefinitely.
