How casting foundries apply techniques for best shaping product?

In India, the alloy casting exporters and manufacturers use different casting processes which are classified as Ingot casting or mould casting. In the Casting foundries in India, primary or secondary aluminum is cast into slabs, billet and wire during the first process. These products are transformed into semi finished and finished products. In the second process, casting foundries use alloy castings for producing cast products.

The mold casting is of two types :
  • Sand Casting
  • Die Casting
Some foundries in India are also using lost wax type casting production technique, but these above two are economically cheaper than lost wax casting.
