Q

PE Extrusion Output Decline

A

For long-term PE extrusion output decline, first measure the screw gap—this is the most decisive hardware indicator; output is a barometer of equipment health; do not just rely on raising the screw speed to hold on, as that will further accelerate wear.

Q

PE Pipe Ovality and Wall Thickness Unevenness

A

PE pipe ovality and wall thickness are jointly determined by 'sizing + cooling + haul-off + die concentricity': first get the die concentricity and sizing right, then stabilize the synchronization of extrusion and haul-off, and only then can the geometric accuracy be guaranteed.

Q

PC FDM Weak Interlayer

A

PC printing weak interlayer relies on the high-temperature chamber; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
