OVERVIEW OF INVESTMENT CASTING
PROCESS
Investment casting, often called
lost wax casting, is regarded as a precision casting process to
fabricate near-net-shaped metal parts from almost any alloy. The
most common use of investment casting in more recent history has
been the production of components requiring complex, often
thin-wall castings.
The investment casting process
begins with fabrication of a sacrificial pattern with the same
basic geometrical shape as the finished cast part. Patterns are
normally made of investment casting wax that is injected into a
metal wax injection die. Once a wax pattern is produced, it is
assembled with other wax components to form a metal delivery system
, called the gate and runner system. The entire wax assembly is
then dipped in a ceramic slurry, covered with a sand stucco, and
allowed to dry. The dipping and stuccoing process is repeated until
a shell of ~6-8 mm is applied.
Once the ceramic has dried, the
entire assembly is placed in a steam autoclave to remove most of
the wax. After autoclaving, the remaining amount of wax that soaked
into the ceramic shell is burned out in a furnace. At this point,
all of the residual pattern and gating material is removed, and the
ceramic mold remains. The mold is then preheated to a specific
temperature and filled with molten metal, creating the metal
casting. Once the casting has cooled sufficiently, the mold shell
is chipped away from the casting. Next, the gates and runners are
cut from the casting, and final postprocessing (sand blasting,
machining) is done to finish the casting.
