PET coffee machine part
문제 현상
Coffee machine water tanks crack after long-term contact with hot water
원인 분석
In hot water environments, PET hydrolysis accelerates, and stressed parts gradually become brittle and crack; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
해결 방법
Select hydrolysis-resistant grades for hot water contact parts or switch to Tritan/PP; verify by hot water cycle life; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
Hot water parts must be selected with hydrolysis-resistant materials; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
