In the history of industrial manufacturing techniques, casting is the oldest one. However, modern advancements in technology have led to a host of casting methods and techniques. But before we get into that, here is what casting actually is. It is a process that allows molten metal to be poured in a specially designed mold to take various shapes and forms. The different casting processes are used to form a variety of finished products – construction supplies, mechanical devices, aerospace parts, etc. Listed below are the top hot forming processes.


  1. Sand Casting
  2. Investment Casting
  3. Plaster Casting
  4. Die Casting

Sand Casting

This process typically involves the usage of synthetic or silica0based sand that can be used to create a smooth molding. This is an excellent option as it can be used for both ferrous and non-ferrous metals. It, however, is excellent for casting a relatively low-tearing capacity and a moderate degree of flexibility during the cooling process. The only downside is that it tends to create a rough finish and is low on accuracy.  Engine blocks, automobile parts are usually manufactured through sand casting.

Investment Casting

This process is the oldest method used by industrial casting manufacturers. It uses wax patterns for each part and is injected directly into the mold. The molten metal is then poured into the same and is allowed to harden and take the shape of the wax. The process is exceptional because it gives a high degree of accuracy and dimensional stability. The surface finish is also neat and smooth, making it slightly more expensive forms. Other than automotive, aerospace parts are also manufactured using the same.

Plaster Casting

With similarities to the sand casting process, this process uses gypsum, strengthening compound and water instead of sand. The plaster material is poured in the mold and allowed to cool down. This process creates a very smooth finish surface and has the ability to cast complex structures with thin walls. Additionally, this provides a higher degree of accuracy as opposed to the sand casting procedure.

Die Casting

This process is used for molding non-ferrous metals and alloys under high pressure to create uniform designs. Metals such as zinc, tin, copper, etc are the top ones. The mold is lubricated to regulate the temperature as well as metal ejection. Once injected, the metal is allowed to solidify under high pressure. After the process, the component is taken out of the die casting and a high degree of accuracy is achieved.

Among all the processes, Die-Casting is suitable for industrial casting manufacturers and Govind Steel is one of them. Govind Steel Company Limited is a 55-year-old company that has continually grown to become one of the largest and leading foundries for Grey Iron Castings and Ductile Iron Castings in India, with an installed capacity of 24, 000 MT.
