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

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 Reduced Toughness

A

For toughness decline, check excessive drying and degradation; 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

Q

TPU Silver Streak Moisture Dominant

A

When TPU shows silver streaks, suspect drying first; the three checks of dew point, moisture content and reabsorption are the fixed opening moves; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying TPU; silver streak; moisture; dew point; drying

Q

TPU Bubble Cause Distinction

A

TPU bubbles are identified by the three routes before treatment; 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

Q

TPU Medical Application

A

Medical TPU is the highest standard of drying and defect control; the 0.02% red line plus zero tolerance protects biological safety; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying TPU; medical; 0.02%; sterilization; biocompatibility

Q

TPU Film Extrusion

A

TPU film is a double high standard of drying and filtration; the 0.02% red line plus precision filtration is the foundation of transparency; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying TPU; film; gel particle; heat sealing; filtration

Q

TPU Polyester vs Polyether Selection

A

Polyester and polyether are selected according to the humid-hot environment; 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 fu...
