ABS delamination and peeling
문제 현상
Sheet-like or film-like peeling appears on the product surface; in severe cases, the surface layer can be directly torn off; it occurs mostly near the gate and at the edges.
원인 분석
The most common cause is mixing of incompatible materials: mixing of different resins, contaminated regrind, mismatched color masterbatch carrier, incomplete purging; excessive mold release agent or high water content in the raw material can also induce delamination.
해결 방법
①Investigate and eliminate mixing contamination, standardize regrind management; ②thoroughly purge when changing material; ③select a color masterbatch carrier compatible with ABS; ④control the amount of mold release agent; ⑤ensure the raw material is dry.
핵심 요약
For ABS delamination, first check 'compatibility and contamination': mixing, color masterbatch carrier, and purging are the three major suspects, don't suspect the process first; delamination is an interface problem, and only by finding the pollution source can it be cured.
