Casting
is a process of manufacturing, in which a 'liquid'
material or a metal is poured into a ‘mold’
which has a desired shaped hollow cavity, and
then made to solidify. Casting can be used to
give any complex shape to the liquid metal which
is not possible through other methods. There
are different types of castings such as iron
castings, aluminium castings etc.
When the molten metal is forced into the cavities
of the mold under high pressure then that type
of casting is referred to as die casting or
sometimes high pressure die casting. If aluminium
is used as the molten metal in this process
then it is referred to as aluminium high pressure
die casting.
If an aluminium casting is used in place of
an iron casting then it will reduce component
weight by half. Aluminium alloys are more utilized
in die casting than alloys of any metal.
That is why auto producers are searching the
areas where they may replace iron parts with
aluminium parts. That is why automotive aluminium
casting is in more demand these days.
The whole process of aluminium high pressure
die casting is accomplished by using the die
casting machine which consists of a source of
molten metal; a rotatable annular ring having
a vertical axis of rotation and being sized
and shaped to carry casting molds; a drive means,
for indexing molds to the source of molten metal
by rotating the annular ring; a demolder means
for transferring ingots from the molds and a
cooling line for cooling ingots; a conveyer
for moving ingots along the cooling line; a
cooling tunnel for enclosing the conveyer; a
source of cooling water to spray the ingots
moving within the cooling tunnel; and a countercurrent
air flow to provide additional heat exchange
with the cooling ingots.
