Uneven core rod temperature in PET bottle injection-stretch-'2079851475616104457
문제 현상
When the PET preform is heated and stretched on the core rod, the core rod temperature distribution is uneven, causing local overheating or overcooling of the preform.
원인 분석
Some core rod heating elements fail or power distribution is uneven; the temperature control system responds with lag; scale on the core rod surface affects heat transfer.
해결 방법
Check and replace heating elements; optimize temperature control parameters; regularly clean the core rod surface; use infrared thermometry to verify temperature distribution.
핵심 요약
PET core rod temperature uniformity is critical to preform stretching consistency.
