Pitting on the mold cavity
Fenómeno do problema
After long-term PEI processing, dotted corrosion pits appear on the mold cavity surface
Análise das causas
PEI may release trace amounts of corrosive substances during high-temperature (>380°C) processing; high temperature accelerates the corrosion reaction rate
Solução
Use mold steels with excellent corrosion resistance (such as S136, 420 stainless steel, etc.); nitriding or PVD coating protection on the mold surface
Conclusão principal
PEI processing has a certain chemical corrosiveness on molds, requiring corrosion-resistant mold materials
