Q

TPU Extrusion Pressure Fluctuation

A

TPU extrusion pressure is a live detection of moisture; for abnormal fluctuations, check drying first, then check others; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Drying TPU; extrusion; pressure fluctuation; moisture; monitoring

Q

TPU Extrusion Bubbles

A

Bubble management for TPU extrusion is stricter than for '2079851475616104452; the 0.02% red line plus pressure stability is the foundation of surface quality; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

TPU Poor Surface Gloss

A

TPU surface gloss is a double mirror of mold and material; polishing, drying and less release agent work together; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying TPU; gloss; mold polishing; drying; release agent

Q

TPU Weld Line Strength

A

TPU weld line treatment prioritizes temperature, relocates position, and assists with venting; stressed areas must avoid weld lines; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Molds & Tooling TPU; weld line; meld line; convergence; venting

Q

TPU Insufficient Filling

A

TPU short shot relies on temperature, speed and gate; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
