High LCP Mold Maintenance Frequency and Cavity Contamination
문제 현상
【Problem Phenomenon】In LCP mass production molds, deposits accumulate relatively quickly on vent grooves and parting lines, requiring frequent mold stoppage for cleaning
원인 분석
During LCP high-temperature molding, low-molecular components and additives precipitate out and deposit on vent grooves and parting lines to form dirt, gradually affecting venting and appearance; Misumi lists high mold maintenance frequency as a difficulty of LCP molding
해결 방법
Make a regular cleaning and maintenance plan for vent grooves, using ultrasonic or special cleaning agents; monitor the precipitation trend for advance maintenance; if necessary, adjust the vent groove structure for easier online cleaning
핵심 요약
LCP precipitation contamination must be included in mold preventive maintenance; clean on a cycle to preserve venting; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
