Q

Screw and Barrel Wear of PEEK

A

PEEK equipment wear is a progressive quality risk; establishing a wear measurement archive enables predictive maintenance; high-temperature-resistant and wear-resistant equipment configuration is the basic investment for long-term stable PEEK production.

Q

Black Speck Prevention and Control of Medical-Grade PEEK

A

Medical PEEK black speck prevention and control is a three-in-one project of environment, equipment, and raw material; metallographic analysis is a sharp tool for tracing; screw wear management should be incorporated into the preventive maintenance plan.

Q

Black Specks and Carbonized Particles in PEEK

A

Tracing PEEK black specks requires combining metallographic analysis to locate the carbonization source; equipment dead spots are the root cause; the high material cost makes the cost of black-speck scrap far exceed that of ordinary plastics, so preventive purging is the most economical.

Q

PE Film Splitty and Weak Edges

A

PE film splitting = 'orientation imbalance', and the core is adjusting the matching of the blow-up ratio and draw-down ratio; weak edges are a knife and tension problem—do not confuse the two and adjust the process randomly.

Q

PE Pipe Surface Roughness and Black Specks

A

Troubleshoot PE pipe appearance in the order of 'plasticization → raw material → cleanliness': for roughness look at plasticization and raw material, for black specks look at carbonization and contamination; drinking water/gas pipes have zero tolerance for black specks, and shutdown management mu...
