TPU Mold Temperature Controller
Problem Phenomenon
TPU mold water temperature controller fluctuates
Cause Analysis
The temperature control accuracy of the water temperature controller is insufficient; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Solution
Regular maintenance of the mold temperature controller; water channel cleaning; mold temperature locked and recorded; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
Mold temperature stability relies on equipment maintenance; 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
