What Is Sand Casting?

Sand casting is one of the most established metal forming processes and remains a practical solution for producing metal components with flexible geometry, broad material compatibility, and controlled tooling cost.
It is widely used across industrial, automotive, energy, and machinery sectors.

Typical workflow:

Pattern preparation (wood, metal, or resin)

Sand mold forming and compaction

Mold assembly and gating setup

Metal pouring

Solidification and cooling

Shakeout, cleaning, and finishing

Because molds are destroyed after each pour, sand casting allows high design freedom without permanent tooling constraints.

• Cast iron (gray iron, ductile iron)

• Carbon steel and low-alloy steel

• Stainless steel

• Aluminum alloys

• Copper-based alloys (bronze, brass)

Strengths of Sand Casting

Low tooling cost compared to permanent molds

Scalable part size, including very large components

Broad alloy compatibility

Flexible design iteration, suitable for early-stage development
