Q

TPU Workshop Humidity

A

The seasonal quality fluctuation of TPU originates from ambient humidity; compensate drying in the rainy season plus workshop dehumidification to keep the weather outside; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying TPU; plum rain; humidity; compensation; dehumidification

Q

TPU Back Pressure and Screw Speed

A

TPU plasticization management is temperature-primary, with back pressure and speed as auxiliary; shear heat is the invisible driver of discoloration and degradation; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Processing Machinery TPU; back pressure; screw speed; shear heat; plasticization

Q

TPU Mold Temperature 20-70°C

A

TPU mold temperature is the balance between surface and stress; fine-tune within the 20-70°C range according to hardness and appearance requirements; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Molds & Tooling TPU; mold temperature; 20-70°C; surface; stress

Q

TPU nozzle drooling management

A

TPU drooling treatment starts from the three lines of temperature, back pressure, and suck-back; the anti-drooling nozzle is the radical solution for high-end parts; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
