Q

PEI Screw Shear Overheating

A

The 20~60rpm and 1~5MPa back pressure in PEI screw management are quantitative guidance; low-shear configuration protects heat-sensitive materials; actual temperature measurement prevents gauge display distortion.

Q

PEEK L/D Ratio Screw Adaptation

A

For complex PEEK parts, first check the screw L/D and compression section; if the configuration is wrong, machine adjustment is futile; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
