Sink Marks of Products Due to Insufficient Holding Pressure in PCTG '2079851475616104452
문제 현상
Depressions (sink marks) appear on the product surface, especially at the thick-walled parts.
원인 분석
The holding pressure or time is insufficient, the shrinkage compensation is inadequate, and the gate solidifies prematurely, cutting off the shrinkage compensation.
해결 방법
Increase the holding pressure and extend the holding pressure time; enlarge the gate to delay solidification; optimize the V-P switchover point.
핵심 요약
PCTG sink marks are a common defect of insufficient holding pressure.
