POM mold deposits (mold fouling)
문제 현상
After continuous production, waxy/powdery deposits appear on the mold surface, and the product surface is scratched and loses gloss.
원인 분석
During POM processing, escaping gases and low-molecular substances condense and deposit on the mold surface; deposition accelerates during high-speed production, poor venting, and high melt temperature.
해결 방법
①Regularly clean the mold surface; ②ensure unobstructed venting and improve venting capacity; ③control the melt temperature within the recommended range; ④record the cleaning cycle and include it in maintenance.
핵심 요약
POM mold fouling = a high-frequency maintenance item, and venting is the line of defense.
