1) The cold die casting machine is
generally used for high melting aluminum alloy die casting.
2) The aluminum alloy has a low
density and can be used for complex and large molding.
3) Eccentric casting of cast aluminum
4) The slightly thicker aluminum alloy
dies casting door
5) Die-cast aluminum dies are generally
oily (and water-based)
Advantages
of Aluminum Die Casting Supplier:
1. The aluminum alloy has good thermal
conductivity, electrical conductivity and cutting performance.
2. The aluminum alloy has a small
linear shrinkage and good filling performance
3. The aluminum alloy has low density
and high strength. The ratio of tensile strength to density is
9-15. It can also maintain good mechanical properties when working at high
or low temperatures.
4. Aluminum die casting refers to
equipment made of pure aluminum or aluminum alloy and molded
components. Aluminum or aluminum alloy parts of various shapes and sizes
are generally referred to as aluminum castings. However, aluminum alloy
die casting can produce different types and effects.
5. Aluminum alloy castings have high
mechanical properties after a natural aging treatment. When the mass
fraction of zinc is greater than 10%, the strength is significantly
improved. The defects of the alloy are poor resistance to corrosion, a
high tendency to stress corrosion and easy hot cracking of the molded parts.
How
is the high-pressure casting process performed?
1. During the
die casting process, the molten metal is injected at high speed and under high
pressure into the mold.
2. Horizontal
high pressure casting machines fully guarantee the complete closure of the
mold. They are classified according to the closing force they can
reach. This force is between 550 and 5,600 tones for Italpresse Gauss
machines.
3. Depending
on the metal used, the injection system that fills the mold may be of the hot
chamber or cold room type. During hot chamber die casting, the metal is
held in the die-casting machine, then introduced into the container and
forcefully pushed by the injection piston directly into the mold. These
parts of the machine are constantly in contact with the molten metal.
4. In the
cold-room process, the metal is first melt-processed in a separate oven, then
transferred to a holding oven, and then poured into a container and injected
into the mold.
Advantages
of the high-pressure casting process
×
These machines make high precision light alloy
parts, superior surface finish, excellent uniformity and optimum mechanical
properties.
×
The Zinc Die Casting casting
process also produces thin-walled components and castings with different types
of inserts, such as screws and coatings, which then become an integral part of
the product itself.
Application
×
Cold chamber high pressure casting technology
is ideal for the production of a large number of cast aluminum and magnesium
automotive parts, such as engine blocks, gearboxes, oil pans, engine cradles.
×
It is widely used in other sectors to
manufacture components for applications ranging from the simplest component
(lighting component) to the most demanding (engine parts for aeronautics).
