Calmet is one of the leading Suppliers who supply cast iron and machined cast iron in both India and China at a lower price without compromising on the quality. Studies have also shown that in USA and Europe even with a multimillion dollar investment in the foundry, the cost of Chinese and Indian supply of iron casting was 30-50% cheaper than doing them in-house. The cost of high metal scrap and pig iron and the strong Euro continue to reduce the profit of metal casters, in Germany which has also made them look out for low cost casting suppliers from India and China. India is the new china… sort of. Production costs in India from the US view point are now lower than china although transportation is slightly higher but the net result is that the landed cost is lower.

Machined iron casting and iron casting are widely used in Automotive industry, Industrial pump industry, Industrial valve industry, general engineering industry. Since cast irons are used in a more wide variety of industries, the automotive and heavy equipment sectors tend to be the primary end users of the materials, making products such as brake disks in mass quantities and large pumps in short production runs, respectively. In the past 10 years, the amount of iron used in a typical north American family vehicle has plummeted 86lbs in the year 2001. The European automotive industry has also had success using casting. Typically a company sends a CAD solid model of the design to the United States , Germany, for pattern design.

Iron casting suppliers take utmost care to understand the technical requirements of the product and understand the drawings received. As far as iron castings are concerned the weights are the base of prices. The suppliers of iron casting need to have the ability to estimate the rough casting weights according to machined weights. Iron casting suppliers in India also have the machining workshops and hence supply the machined iron castings.
