Abnormal In-Mold Pressure Curve in PBT '2079851475616104452
문제 현상
The in-mold pressure sensor curve shows an abnormal shape (double peaks or multiple peaks), and the filling is unstable.
원인 분석
During multi-gate filling, the arrival times of the melt streams are different, producing pressure fluctuations; cold material entering the cavity causes this.
해결 방법
Optimize the runner balance; increase the melt temperature and mold temperature; use a cold slug well to capture cold material.
핵심 요약
The PBT in-mold pressure curve is the basis for filling quality diagnosis.
