Q
Uneven cutting end face of general-purpose polyethylene pipes
A
Uneven cutting end face is caused by tool wear or improper cutting parameters, and the tools need to be maintained and the cutting process optimized.
Processing Machinery cutting end face cutting tool cutting speed pipe cooling cutting machine calibration
Q
Excessive gels/gel particles in general-purpose polyethylene extruded products
Q
General-purpose polyethylene pipe pressure test failed
Q
Large current fluctuation of general-purpose 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.
