Thin flash appears at the parting line or moving parts of the product
문제 현상
Thin flash appears at the parting line or moving parts of the product, affecting appearance and dimensional accuracy, mold mating marks visible at the flash
원인 분석
Injection pressure too high, exceeding the mold clamping force
Mold mating surfaces worn or machining accuracy insufficient
Barrel temperature too high (170-230°C on the high side), low melt viscosity, excessively strong flowability
Holding pressure too high, time too long
Clamping force insufficient
해결 방법
Reduce injection pressure to a reasonable range
Repair mold mating surfaces to ensure accuracy
Appropriately lower barrel temperature to the low side of 170-230°C
Reduce holding pressure and time
Increase clamping force or change to a larger machine
핵심 요약
Flash requires controlling injection pressure, temperature and clamping force
