Investment Casting - DS SX Solidification

I will try to explain what I do
for leaving and what kind of company I work for. Investment casting is also
known as the lost wax process.
This process is one of the oldest
manufacturing processes. The Egyptians used it in the time of Pharaohs to make
gold jewelry (hence the name Investment) some 5,000 years ago.
Intricate shapes can be made
with high accuracy. In addition, metals that are
hard
to machine or fabricate are good candidates for this process. It can be used to
make parts that cannot be produced by normal manufacturing techniques, such as
turbine blades that have complex shapes, or airplane parts that have to
withstand high temperatures.
In the
directiona l solidification process, molds are
preheated well above the melting temperature
of the alloy. Once the mold is
fully heated,
the alloy is poured into the mold and cooled in controlled
fashion. After that the mold is pulled trough a temperature gradient from the
warm side, where the alloy is molten, into cold side, where the alloy is solid.
Parts made with investment casting often
do not require any further
machining, because of the close tolerances that can be achieved.
