Metal
Casters have the luxury of choosing between several casting methods to
accomplish their goals. Often times the metal caster chooses one method and
sticks with it for several years until need directs him to another. Of course,
there are those adventurous few who like to sample each casting method to find
the best fit. Sure, sand casting might be the most popular but what about Lost
Foam or Investment?

What about Die casting?

Die casting is used by industrial foundries and manufacturers to create
practically anything and everything, such as die cast cars. Many small
foundries, like the one in your garage, backyard, of workshop may find that die
casting is really just not economical. But who said that having fun and trying
new things was ever economical? The process of Die Casting involves a simple
concept. The molten metal is injected with high pressure into the mold or mold
cavities. The mold used in die casting can have several small civilities of
either the same pattern or different pattern.

The name Die Casting comes from the molds which are called dies. These molds
are reusable and are often made from steel but other alloys can be used as long
as they can withstand high pressure. The reason dies must be created from metal
and not from sand or other material is due to the high amount of pressure used
to get the molten metal into the mold. If sand molds were used in a Die casting
procedure then the mold would crumble. There are plenty of advantages of using
dies in a casting procedure which makes this method desirable for anyone
wishing to create a high volume of similar castings.

Die casting is perfect for anyone that needs to make a lot of the same thing
without any quality or pattern deviation. This is especially helpful in certain
industries where quantity and quality count. Many hobbyists may have no use for
die casting on a practical basis but will often try at least one Die casting
for the sake of trying.

There are two types of machines used in the Die Cast procedure. These machines
are essentially the same and are called the Hot-chamber and the Cold-chamber.

The Hot-chamber machine melts the alloy and feeds it into a section of the
machine referred to as the gooseneck. A piston then forces the alloy into the
mold. A separate furnace is not needed but the draw back of this is that metals
with higher melting points can not be used.

The Cold-chamber is used for metals that can not be used by the Hot-chamber
such as aluminum and copper. A separate furnace is needed to melt the alloy
which is then poured into the injection cylinder and then shot into the mold.

The advantages of using Die casting vary but the most noticeable advantages are
the repeated quality, smooth casting surface, and the quick production of
casts. While the initial cost of Die Casting exceeds several of the other
casting procedures, those that need a high number of casts in the shortest
amount of time possibly will benefit greatly from the investment.

Die casting is commonly used to create commercial goods as it yields a high
volume. The molds, or dies, used vary in life cycle depending upon the material
used to create the die. The die can have one cavity or several cavities
depending upon the need.

Everyone should try die casting at least once if they can afford the initial
cost. Besides , who knows when you’ll need a small battalion of metal soldiers
which can be made quickly and easily with die casting.
