Q
Unreasonable die head flow channel design of heat-resistant polyethylene extruder
A
Die head flow channel design needs to ensure uniform melt distribution and no material stagnation, and the die head should be redesigned when necessary.

Q
Heat-resistant polyethylene pipe ovality exceeding standard
Q
Mechanical properties of heat-resistant polyethylene extruded products not meeting standard
Q
Excessive gel/gel particles in heat-resistant polyethylene extruded products
Q
Bending deformation of heat-resistant polyethylene extruded pipes
A
Pipe bending is caused by non-uniform cooling or haul-off eccentricity, and needs to be solved from cooling uniformity and equipment alignment.

Q
Heat-resistant polyethylene pipe pressure resistance test failure
Q
Die marks/lines appear on heat-resistant polyethylene extruded products
A
Die marks are caused by die inner wall damage or impurities, and the die condition needs to be regularly cleaned and inspected.

Q
Large current fluctuation of heat-resistant polyethylene extruder
A
Current fluctuation is caused by large plasticizing resistance or equipment problems, and needs to be solved from temperature control, raw material purity and equipment maintenance.

Q
Poor plasticization caused by screw wear of heat-resistant polyethylene extruder
A
Screw wear leads to decreased plasticizing efficiency, and needs to be solved by selecting wear-resistant materials and regular maintenance.
