EMA Injection Molded Products Have Oil Spots
문제 현상
After demolding, oil spots appear on the surface of EMA injection molded products, mold release agent residue or lubricant exudation
원인 분석
Mold release agent sprayed too much or unevenly distributed; internal lubricant stearic acid type in EMA exudes to the surface; mold lubricating oil seeps into the cavity
해결 방법
1) Reduce mold release agent dosage or switch to dry-film release agent; 2) Use internal lubricant instead of external release agent; 3) Seal the mold lubrication parts to prevent oil from seeping into the cavity; 4) Clean the product surface to remove oil spots and then detect the source
핵심 요약
Oil spots are caused by external sources of release agent and lubricant; reducing release agent and sealing mold lubrication are key
