Aluminium Alloy Die Casting

Key Features of the Aluminium Alloy Die Casting Process:

(1) Mold Preparation: The process begins with the preparation of a robust steel mold, which is designed to withstand the high pressures and temperatures involved in die casting. The mold is treated with a release agent to facilitate easy removal of the finished casting.

(2) Melting the Alloy: Aluminium alloy is melted in a furnace until it reaches a liquid state. The temperature is carefully controlled to ensure optimal fluidity and quality of the molten metal.

(3) Injection: Once the alloy is molten, it is injected into the mold at high pressure, typically ranging from 1,000 to 3,000 psi. This high-pressure injection ensures that the molten metal fills all intricate details of the mold, resulting in a high-quality casting.

(4) Cooling and Solidification: After the mold is filled, the molten aluminium cools and solidifies rapidly. The cooling time can vary depending on the thickness of the casting and the specific alloy used.

(5) Mold Removal: Once solidified, the mold is opened, and the casting is removed. The finished product is then subjected to quality inspections to ensure it meets the required specifications.

(6) Finishing: Any necessary finishing processes, such as machining, surface treatment, or coating, are performed to achieve the desired specifications and enhance the product's performance.
