casting aluminum is a manufacturing method to create metal parts. An aluminum
bar should be heated and melted entirely at a high temperature and then
forced into the pre-shaped mold cavity to create desired metal parts.The end
product comes out with a smooth surface. Most of the time, the finished
products don’t need minimal machining and move into the delivery stage
quickly. Moreover, the die-cast mold is recycled to manufacture the same
parts before it deteriorates. Therefore, aluminum die casting is an ideal
manufacturing process for large-scale production. And that is why
manufacturers prefer to die casting this and it is popular in various
Cold Chamber Aluminum Die Casting
The aluminum die casting process uses the casting machine’s cold chamber. In the cold chamber machine, the melting pot is separated and the molten aluminum alloys then are ladled from the pot into the die under high pressure. After injecting the molten aluminum, it takes a while to solidify. Then, you need to separate the two halves parts of the mold to reveal the aluminum cast part.
Aluminum is injected into the die under high pressure using fully automatic high-pressure casting machines.The aluminium die casting machine opens the die when the molten metal has set, and the die casting parts are ejected.
cycle is repeated quickly, so that many hundreds of cast parts can be made
each day. This casting technique is highly suitable for thin-walled casting.
Perfect for saving weight. High-pressure die casting is extremely suitable
for casting with high dimensional accuracy and for batch sizes with more than
2,500 pieces. In many cases, the great dimensional accuracy of this die
casting process eliminates the need to finishing service, thus significantly
reducing finishing costs.

Material Grades Available For Aluminium Die Casting
Alloy A380 (ANSI/AA A380.0) is by far the most widely
cast of the aluminum die casting alloys,offering the best combination of
material properties and ease of production. It may be speci ed for most
product applications. Some of the uses of this alloy include electronic and
communications equipment, automotive components, engine brackets, transmission and gear cases, appliances, lawn mower housings, furniture
components, hand and power tools. Alloy A380 has better than average
If your component is highly intricate, 383——is often used as an
alternative to A380.It has better corrosion resistances, is lightweight, and
its benefits include ease of casting, good mechanical properties, and
A413 is an aluminum alloy with excellent pressure
tightness. This makes it a good choice for hydraulic cylinders. The
castability of this aluminum alloy makes it a great choice for die casting
Alloy 390 (ANSI/AA B390.0)is an aluminum
alloy with high hardness and good wear resistance. This alloy is suitable for
many applications including internal combustion engine pistons and cylinder
bodies for compressors and brakes.
413 is an Aluminum based alloy that is used for die
casting parts. 413 has many benefits:It offers a good combination of casting,
mechanical, and thermal properties and it exhibits excellent fluidity,
pressure tightness, and resistance to hot cracking.It is used for a wide
variety of products.

Advantages of Aluminum Die Casting
Pressure die casting aluminum alloy components have the following advantages compared to the ones made by other casting methods.
✔ High productivity ✔Low wastage in the metal casting process ✔The very thin section can be casted easily ✔Do not require further machining ✔Good as-cast surface finish and appearance ✔Can be casted within close dimensional tolerance ✔Rejection due to casting defects is low
