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.
Wax pattern preparation
Mold making
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
Wax removal through melting and burnout
Shell Testing
Metal Pouring
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.
