Poor hot runner balance in PET '2079851475616104452
문제 현상
The output of each nozzle of the PET hot runner system is uneven, and product weights of multi-cavity molds differ greatly.
원인 분석
The flow paths of each hot runner are unequal with different flow resistances; heating temperatures of each nozzle are uneven; rheological balance calculation was not performed.
해결 방법
Adopt natural balance or rheological balance design; use temperature-adjustable nozzles; optimize runners with mold flow analysis; regularly clean the hot runner.
핵심 요약
PET hot runner balance is a core requirement of multi-cavity precision '2079851475616104452.
