Aluminum, Zinc and Copper alloys
are the materials predominantly used in die-casting.
On the other hand, pure Aluminum is rarely cast
due to high shrinkage, and susceptibility to hot
cracking. It is alloyed with Silicon, which increases
melt fluidity, reduces machinability. Copper is
another alloying element, which increases hardness,
reduces ductility, and reduces corrosion resistance.
Aluminum is cast at a temperature of 650 ºC
(1200 ºF). It is alloyed with Silicon 9%
and Copper about 3.5% to form the Aluminum Association
380 alloy (UNS A03800). Silicon increases the
melt fluidity, reduces machinability, Copper increases
hardness and reduces the ductility. By greatly
reducing the amount of Copper (less than 0.6%)
the chemical resistance is improved; thus, AA
360 (UNS A03600) is formulated for use in marine
environments. A high silicon alloy is used in
automotive engines for cylinder castings, AA 390
(UNS A03900) with 17% Silicon for high wear resistance
Aluminum Die Cast Parts produced by Kinetic Die
Casting, Inc. can be stronger than steel. Kinetic
Die Casting Company is a part diecaster of lower
priced, better quality aluminum die cast parts,
sometimes also known as castings, aluminum part
castings, high pressure part die castings, or
aluminum diecastings. Kinetic Die Casting has
Low Quantity Die Casting Production or High Quantity
Die Casting Part Production.
High pressure die casting is a process we use
to make aluminum die cast parts. We inject molten
aluminum alloy metal under pressure into a steel
die to produce aluminum parts. Diecasting is a
very inexpensive aluminum part manufacturing process.
Primarily we produce aluminum alloy die castings,
but we also make some diecastings in zinc alloys.

die cast tooling, machining of die cast parts
and finish the surface of many kinds of die cast

nes, and big machines are expensive. Few shops
can afford to pay hundreds of thousands of dollars
just to machine a few flats on a workpiece, or
drill and tap some holes.
But what if you can split the problem in two
pieces? Why not separate the machining requirements
from the workpiece handling and holding requirements,
and then apply--and integrate--mechanisms that
are appropriate to their specific tasks?

That's really the philosophy behind the extremely
efficient transfer systems that have been applied
for decades in the automotive and other high-volume
industries. For a simple operation, move the part
to a machining station designed for the task,
execute the operation, and move on. The good news
for those machining on a smaller scale is that
technology now exists that can apply the same
low cost machine parts concept at a much lower
cost, yet at a much higher degree of flexibility.
It's primarily a matter of combining the inherent
versatility of a simple, low-cost machining center
with a workpiece handling system designed for
the task at hand.
Here's how the concept plays out at one manufacturer.

In terms of feasibility, many aluminum alloy
castings can be produced by any of the available
methods. For a considerable number of castings,
however, dimensions or design features automatically
determine the best casting method. Because metal
molds weigh from 10 to 100 times as much as the
castings they are used in producing, most very
large cast products are made as sand castings
rather than as die or permanent mold castings.
Small castings usually are made with metal molds
to ensure dimensional accuracy.
Quality factors are also important in the selection
of a casting process. When applied to castings,
the term quality refers to both degree of soundness
(freedom from porosity, cracking, and surface
imperfections) and levels of mechanical properties
(strength and ductility).
However, it should be kept in mind that in die
casting, although cooling rates are very high,
air tends to be trapped in the casting, which
gives rise to appreciable amounts of porosity
at the center. Extensive research has been conducted
to find ways of reducing such porosity; however,
it is difficult if not impossible to eliminate
completely, and die castings often are lower in
strength than low-pressure or gravity-fed permanent
mold castings, which are more sound in spite of
slower cooling.
