Aluminium Die Casting Parts

Aluminium Die Casting Machining Part

Aluminium Die Casting is one kind of method of metal processing. It generally uses the gravity of metal to casting in the mold. But aluminium die casting is not done by its own gravity but also with external pressure. That enhanced aluminium die casting parts own excellent performance in various industries. Such as copper, zinc, aluminium or aluminium alloy, which is heated to a liquid state, is poured into the inlet of the die-casting machine, and casting copper, zinc, aluminium or aluminium alloy parts with limited shapes and sizes of the mold, such parts are usually called die casting parts.

  Aluminium Die Casting Parts  

Aluminium die casting parts are among the highest volume, mass-produced items manufactured by the metalworking industry, and they can be found in thousands of consumer, commercial, and industrial products. Aluminium die casting parts are important components of products ranging from autos to toys. Parts can be as simple as a sink faucet or as complex as a connector housing. Aluminium die casting part is a great choice for manufacturing parts with a highly valued combination of lightweight and superior strength at a high rate.


Aluminium Die Casting Parts


  How Are Aluminium Die Casting Parts made?  

1. Need at least two sections of steel die capable to allow the castings to be removed. Therefore, the process is capable of producing tens of thousands of aluminium casting parts in quick succession.

2. The dies are firmly mounted in the die casting machine, one is stationary (fixed die half) and the other one is movable (syringe half-mold). And the two mold halves are clamped together by a die-casting machine.

3. High-temperature liquid aluminium alloy is injected into the mold cavity and rapidly solidified.

4. Open the movable die half and eject the aluminum casting.

  Advantages of Aluminium Die Casting Parts  

Aluminium Die Casting is an efficient, economical process offering a broader range of shapes and components than any other manufacturing technique.


High Rates of Production: Aluminium die casting provides complex shapes within closer tolerances than many other mass production processes. Little or no machining is required and thousands of identical castings can be produced before additional tooling is required.


Dimensional Accuracy and Stability: Die casting produces parts that are durable and dimensionally stable, while maintaining close tolerances.


Excellent Strength and Hardness: Die cast parts are stronger than plastic injection moldings having the same dimensions. Thin wall castings are stronger and lighter than those possible with other casting methods.


Efficient Machining Process: Aluminium die casting parts can be produced with smooth or textured surfaces, and they are easily plated or finished with a minimum of surface preparation.


Simplified Assembly: Aluminium die casting parts provide integral fastening elements, such as bosses and studs. Holes can be cored and made to tap drill sizes, or external threads can be cast.


In addition, aluminium die casting parts have the advantages of outstanding corrosion resistance, low density, excellent EMI & RFI shielding properties, excellent thermal conductivity, high electrical conductivity, visually appealing appearance, and good mechanical properties.


  CNC Machining VS Die Casting  

Two of the most popular industrial processes for manufacturing aluminium parts are die casting and CNC machining. Often, CNC machining is used to create the die, and/or to add more intricate features after a part has been die cast. Aluminium die casting machining parts is the outcome in combining both processes for the best possible finish. 


CNC machining can create finished parts with great precision and tolerance , especially if they are highly customized small parts, which is able to clean up surface defects such as burrs or flashes of die casting parts. However, die casting is still a great choice for creating identical parts when it comes to high volume production. Die casting is the better choice for consistent quality and quantity. CHAL fully utilizes the advantages of both die casting and CNC machining to reach maximum benefits
