Process of Investment Casting
2
There are various manufacturing process held in
the casting industry for the various needs of the
consumers. Investment casting is also a
manufacturing technique with a ceramic metal or
material is coated by the wax pattern with a
refractory material of ceramic. The internal
geometry and shape during the casting process is
maintained due to the hardness gained by the
ceramic materials.
3
Molted metal is drop to the melted wax and thus
after the process of pouring, the shape of metal
is gained by the melted wax. Investment casting
manufacturer take care of all these process even
in the case, when mold of metal is broken out in
casting process. Various processes are named
differently in many places like Investment
casting is also named as lost wax process.

Steps are involved in the casting process and
these steps are carried out by several Investment
casting manufacturers. Pattern for these types of
process are made up of plastic and then wax is
poured on them to get the same pattern. There are
many manufacturers who offered the maximum
compliance with maximum features and also the
functional usage for the specifications and
perfect finishing.

Hardness is important to control for the
mechanical properties and all these are treated
with some of the specific treatment process.
These things allow the casting of the extremely
complex parts with the manufacturing processes
for a good surface finishing.

Relative expense in the investment casting is a
complicated process. Parts manufactured in the
investment process are automatic. On the other
words we can say that metals are investment cast
in the practical manner.
