Characteristics, advantages and application of die-cast aluminum alloys

Posted by Aluminium Die Casting on December 5th, 2019

Below are benefits of hiring Die Casting Manufacturer:

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).
