TPU Automotive Interior
Problem Phenomenon
Odor complaints about TPU interior parts
Cause Analysis
Residual solvent or degradation products in TPU release odor; 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
Choose low-odor grades; process temperature control; odor test verification; 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
Automotive parts are selected according to odor standards; 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
