       1. In the process of producing PVC pipe, there may be a sudden slow discharge, which may be caused by the machine entering the water and the melt pressure of the machine head is too small.
2. If black streaks appear on the surface of the pipe, this is because the filter is not cleaned before production.
3. If the inner wall of the pipe is rough, this is because the temperature of the mandrel and the machine is low and the temperature of the screw is too high.
