Ceramic Casting Sand Applications
- Used in all types of foundry techniques like coated sand, resin-bonded sand, sodium silicate sand, and clay-bonded sand.
- As molding sand and core-making sand for iron casting, steel casting, and alloy steel casting.
- As a substitute for chromite sand for jacket core-making, oil duct core-making, tappet core-making of the engine.
- As facing sand for large steel castings.
- As dry sand of sandbox for EPC process and V method of casting processes.
