Process of Investment Casting Method
Wax patterns fabricated from an aluminum wax tooling are connected
to the runner as "tree" .
The tree is dipped into refractory slurry until a suitable
thickness of shell is achieved that can hold the molten metal after
the investment is burnt out.
The "Burn-Out" process requires that the investment and coating are
inverted in an oven that is fired to 1800F so that the investment
can flow out and be recovered. The refractory coating is also cured
in this procedure.
This process is beneficial for casting metals with high melting
temperatures that cannot be moulded in plaster or metal.
Parts that are typically made by investment casting include those
with complex geometry such as turbine blades or fire arm
components. High temperature applications are also common, which
includes parts for the automotive, aircraft, and military
Method also called as precision investment casting. The method
involves the use of expendable Pattern with a shell of refractory
material surrounded to form a casting mould. Since the pattern made
up of wax is melted out and gets destroyed. That is why the
name-"Lost wax method".
Refractory slurry is formed around a wax or plastic pattern and
allowed to harden. The pattern is then melted cut under mould is
baked. The molten metal into the mould and solidifies.

By injecting wax into a permanent-molding die to form a pattern,
investment casting get casting parts of good surface quality and
became the solution for many complex parts that are required in
large quantities. The good casting surface quality provides good
base surface for mirror polishing.
