After mixing and burning, the resin sand could become very hard and solid, so we called it as the hard mold. The iron casting made by resin sand will be usually called as resin sand casting.
Technical features:
1. It is suitable for making complex shapes, especially blanks with complex inner cavities;
2. Wide adaptability and low cost;
3. For some materials with poor plasticity, such as cast iron, sand casting is the only forming process for manufacturing its parts or blanks.
Application: automobile engine cylinder block, cylinder head, crankshaft and other castings
