Sand casting can be used for grey iron casting, ductile iron casting, aluminum casting. There are three kinds of molding processes for sand casting. They are manual molding, semi-machinery molding and automatic molding. Automatic molding line is currently mostly for iron castings making.
Automatic molding machines include two kinds of part line: horizontal part line molding and vertical part line molding. DISA line uses vertical part line molding. SINTO ling takes horizontal part line molding. Normally vertical part line molding is faster than horizontal part line molding. But horizontal part line molding can accommodate more complex cores’ assembly and location for more complex structure parts.
The basic grey iron casting process include patterns design and making, molding, melting , inoculants action of the melting, nodular operation ( only for ductile iron) , pouring, cooling, shaking out, de-gating and after-treatment ( deburrs, grinding , shot blast).
