Detail Information

Sand casting is a tranditional but also modern casting process. It uses green sand (moist sand) or dry sand to form the molding systems. The green sand casting is the oldes casting process used in history. When making the mold, the patterns made of wood or metal should be produced in order to form the hollow cavity. The molten metal then pour into the cavity to form the castings after cooling and solidification. Sand casting is less expensive than other casting processes both for mold development and unit casting part. The sand casting, always mean the green sand casting (if no special description). However, nowadays, the other casting processes are also use the sand to make the mold. They have their own names, such as shell mold casting, furan resin coated sand casting (no bake type), lost foam casting and vacuum casting. 

The Advantages of Sand Casting:
✔ Lower Cost due to its cheap and recyclable mold materials and simple production equipment.
✔ Wide range of unit weight from 0.10 kg to 500 kgs or even bigger.
✔ Various Structure from simple type to complex type.
✔ Suitable for production requirements of various quantity.

Tolerance That Sand Castings Achieve:
The casting tolerances are divided into Dimensional Casting Tolerances (DCT) and Geometrical Casting Tolerances (GCT). Our foundry would like to talk with you if you have special request on the required tolerances. Here in the following are the general tolerances grade we could reach by our green sand casting, shell mould casting and no-bake furan resin sand casting:
✔ DCT Grade by Green Sand Casting: CTG10 ~ CTG13
✔ DCT Grade by Shell Mold Casting or Furan Resin Sand Casting: CTG8 ~ CTG12
✔ GCT Grade by Green Sand Casting: CTG6 ~ CTG8
✔ GCT Grade by Shell Mold Casting or Furan Resin Sand Casting: CTG4 ~ CTG7
