The main reason why the PFA tube extruder cannot extrude the material is that:
1. Unreasonable temperature control of PFA extruder screw. If the temperature of the cylinder is too high, the material in contact with the cylinder will melt, and it is easy to cause the material to overheat decomposition, and the temperature of the screw is too low, resulting in the cylinder can not slip, can not be discharged;
2. The blocking of the shunt plate and filter screen makes the movement resistance of the material too large, which greatly reduces the axial movement speed of the material in the spiral groove, resulting in the material can not be discharged.

The solution:
1. Reduce the temperature of the cylinder;
2. Reduce the flow of screw cooling water and increase the temperature of cooling water;
3. Regular cleaning and replacement of shunt plate and filter screen.
Our company has been producing FEP tube and PFA tube for many years, and has accumulated a lot of production experience. Through the continuous improvement of the product, we found a lot of problems in the original extruder. These problems have more or less affected the output and quality of products. Through our improvement, we have helped many peers and PFA tube extruder customers to solve their problems, which has played a certain role in the healthy development of the industry.
