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
