PA12 Medical Catheter Mold Temperature Upper Limit
문제 현상
【Problem phenomenon】PA12 medical catheters had insufficient strength after '2079851475616104452, and traceability found that the mold temperature was set too high
원인 분석
The mold temperature of PA12 for medical catheters is controlled at 35-40℃ (such as Grilamid TR55), and excessively high mold temperature causes amide bond breakage and strength damage; this is a special scenario opposite to the high mold temperature strategy for structural parts
해결 방법
Strictly control the mold temperature of medical catheter parts in the 35-40℃ range; cooperate with a setting temperature of 105-120℃; include strength indicators in the mandatory first-article inspection items; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
The 35-40℃ mold temperature for catheter PA12 is the strength red line, opposite to the strategy for structural parts; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
