Why is the melt pump extrusion unable to discharge?

Reasons and specific solutions for the inability to discharge materials during the use of high-temperature melt pump extrusion:

The reason why the hot melt pump cannot discharge:

1. The rotation direction of the high-temperature melt pump in extruder is reversed, resulting in abnormal discharge;

2. The suction or discharge valve is closed, resulting in the inability to discharge;

3. The channel of the high-temperature melt pump is empty or the inlet working pressure is too low;

4. The viscosity of the conveyed melt is too high, and the high-temperature melt pump cannot bite the material.
