Q
Cooling System Efficiency Decline of Polypropylene Extruder
A
The decline in cooling efficiency is caused by insufficient water volume or excessive water temperature; the cooling system needs to be improved and the water temperature controlled.
Production & Quality cooling efficiencycooling water flowcooling water temperaturewater channel scalingcooling water tank
Q
Sizing Device Failure of Polypropylene Extruder
A
Sizing device failure needs to be solved from three aspects: the vacuum system, the cooling system, and mold precision.

Q
Unreasonable Die Head Flow Channel Design of Polypropylene Extruder
A
The die head flow channel design needs to ensure uniform melt distribution and no material retention; the die head needs to be redesigned when necessary.

Q
Excessive Gel/Gel Particles in Polypropylene Extruded Products
Q
Bending Deformation of Polypropylene Extruded Pipe
A
Pipe bending is caused by non-uniform cooling or haul-off eccentricity, and needs to be solved from cooling uniformity and equipment alignment.
