Excessively long PET preform injection cycle
문제 현상
The PET preform '2079851475616104452 cycle is too long (>25 seconds), and production efficiency is low.
원인 분석
Cooling time is too long (PET crystallization exotherm causes slow cooling); mold cooling efficiency is insufficient; preform walls are too thick.
해결 방법
Optimize cooling water channels to increase cooling efficiency; appropriately reduce mold temperature; thin the preform wall thickness; use rapid heating and cooling technology.
핵심 요약
The PET preform molding cycle directly affects production costs.
