Abstract:
Investment Casting is a metal casting
process which employs an expendable
pattern and one piece non metallic
mould. This process is also known as
Precision Casting because it eliminates
the parting line and reduces the
machining cost. Sometimes, this
process is also known as lost wax
method. Although all metals, namely
ferrous as well as non-ferrous can be
casted by this process, it is most suitable
for expensive, hard and high strength
metals and alloys, which are difficult to
machine. This also includes Stainless
and Tool Steels
