​
Aluminum die casting stands as an excellent choice for crafting components that combine the coveted attributes of lightweight design and exceptional strength, all while maintaining high production rates. With die casting machines spanning a range from 180 to 2,000 metric tons, coupled with advanced CNC machine centers, we possess the capability to manufacture aluminum die casting parts spanning from a few grams to over 40 pounds, all characterized by superior quality and readiness for assembly. Furthermore, for aluminum die casting parts necessitating aesthetic, functional, or protective coatings, we provide an extensive selection of surface finishing options, including powder coating, e-coating, shot blasting, chrome plating, and achieving a bright finish.
What Is Aluminum Die Casting?
The aluminum die casting method is a production technique employed to create precisely sized, sharply delineated, and either smooth or textured-surface aluminum components by utilizing reusable molds known as dies. This process relies on essential components, including a furnace, an aluminum alloy, a die casting machine, and the die itself. These dies, customarily crafted from enduring, high-quality steel, comprise at least two sections to facilitate the extraction of castings.
What does the Aluminum Die Casting process entail?
Aluminum casting dies, constructed from robust tool steel, are designed with a minimum of two sections to facilitate the removal of castings. The aluminum die casting process boasts the capability to generate large quantities of aluminum castings rapidly. These dies are securely affixed within the die casting machine, with one half serving as the fixed die, remaining stationary, while the other half, known as the injector die, is movable. The complexity of aluminum casting dies can vary, involving movable slides, cores, or other components, contingent upon the intricacy of the casting.
​
To initiate the aluminum die casting process, the two halves of the die are brought together and tightly clamped by the casting machine. A high-temperature liquid aluminum alloy is subsequently injected into the die cavity, swiftly solidifying upon contact. Following this, the movable die half is opened, and the aluminum casting is ejected.
​
Remarkably, the comprehensive cycle of aluminum die casting stands as the swiftest method to date for producing precision aluminum parts. This contrasts significantly with sand casting, which necessitates the creation of new sand molds for each casting. Furthermore, although the permanent mold process employs iron or steel molds instead of sand, it considerably lags behind aluminum die castings in terms of both speed and precision.
