Metal Casting Manufacturers in India
India is the second largest exporter of iron, steel and aluminum castings in the world. Labor is cheap in India. Many of America’s leading brands manufacture their castings in India, including GM, Ford, and John Deere. The country is dotted with foundries, but most metal casting manufacturers in India are located in the Rajkot (near Mumbai) or Coimbatore (southern India).
Minimum order quantities tend to be a few hundred pieces or about three to five metric tons. Iron and steel foundries in India think about order quantity in terms of estimated annual units (EAU). This is different from metal casting manufacturers in China who tend to work off quantities for individual orders. A foundry in India will expect blanket orders will be placed to cover a full year of demand.
Foundries in India will typically have in-house quality control capabilities for non-destructive testing. Typical capabilities for quality control include:
- Hardness testing
- Salt spray (corrosion) testing
- Liquid penetrate testing
- Magnetic particle testing
- Ultrasonic testing
- Radiography testing
It is recommended to have a 3rd party around to witness any testing at a foundry in India.
