TPE Product Stress Cracking
Problem Phenomenon
Cracking during use.
Cause Analysis
Internal stress and media action; TPE is sensitive to certain solvents.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Reduce internal stress; ②avoid incompatible media; ③compatibility verification; ④optimize the structure.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
For stress cracking, check stress and media.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
