Oil spots on EEA injection molded products
Fenómeno do problema
Oil spots appearing on the surface of EEA injection molded products after demolding, release agent residue or lubricant precipitation
Análise das causas
Release agent sprayed too much or unevenly distributed; internal lubricant stearic acid type in EEA precipitating to the surface; mold lubricating oil seeping into the cavity
Solução
1) Reduce release agent dosage or switch to dry film release agent; 2) Use internal lubricant instead of external release agent; 3) Seal mold lubrication parts to prevent oil from seeping into the cavity; 4) Clean the product surface to remove oil spots and then test to identify the source
Conclusão principal
Oil spots are caused by external sources of release agent and lubricant; reducing release agent and sealing mold lubrication are the key
