Investment Casting Manufacturer in India
If you have to buy metal parts in India or you need metal components developed and produced for use across various industries, then searching for the best investment casting manufacturer in India will help you find the best deals you can have.
Sumangal Casting Pvt. Ltd. is the leading Investment casting manufacturer and supplier. You can get the expert consultation from idea to implementation and our investment casting process covers all the important touchpoints of quality, reliability, and certainty.
In our modern manufacturing plant, we make the whole range of investment castings. The metal casts are made from ferrous metals and their alloys that consist of the nickel and cobalt super-alloy.
Our manufacturing process has an installed capacity of 600 MT per annum. We manufacture engineering metal components of the highest grade and to do this we use one disposable pattern to produce only one metal part.
Investment casting process
Investment casting is commonly called lost-wax casting and it is one of the oldest metal making process.
This process is used by all investment casting manufacturers to duplicate the features from an original sculpture and cast multiple identical metal parts similar to the sample metal part.
Intricate designs and work can be replicated successfully through the investment casting process.

The fundamental steps conducted for the investment casting process are -
Wax pattern preparation
A mold-maker designs an original wax model that’s similar to the sample metal part.
Mold making
When the wax pattern is made then mold making is required to proceed for the further casting process. An outer rigid mold is prepared by dipping the wax pattern in ceramic slurry and sand-like stucco.
This process of dipping in the slurry is repeated many times to attain the desired thickness of the shell. This outer mold is made in such a way that it becomes the exact negative of the original wax pattern and the sample metal part that needs to be produced.

Spruing
After this, the assembly is sprued with a tree-like structure that’s meant to provide a path for the air to escape and the molten metal to flow.
Wax removal through melting and burnout
The shell-coated wax assembly is put cup-down in a kiln where the shell gets hardened due to the heat and the wax is melted and drains out. This melted wax can be reused.
Shell Testing
The shell is now cooled and tested with flowing water through the vent tubes and feeder to check if it has any cracks in it, these cracks are then patched with a thick paste.
Metal Pouring
Reheating of the shell helps in removing any traces of moisture left in it and it also hardens the applied paste.
Next, the pouring of hot and melted metal in the preheated shell is conducted. To do this, the shells are first placed in a tub of sand with their cups facing upward.
The molten metal is poured into these shells. This is done carefully and it is important to note that the shells should be hot while the metal is poured into them or else they will break if they are cold when the hot and melted metal is poured in them.

Shell Release
The shell is blasted away to release the rough metal cast. For the final steps of finishing the spurs formed on the metal are cut off. These metal pieces are cut off and can be reused in another investment casting process.
Metal chasing
The metal cast is chased. Chasing removes all signs of casting from the metal surface and smoothens it. After being polished the prepared casting now looks like the original model.
