Product Definition
Aluminum alloy castings are aluminum components produced by the gravity casting process, using a mold to achieve their final shape. The forming process primarily relies on the gravitational force of the molten metal itself to fill the mold—making it a widely used method for shaping common metal parts.
Molding Process
The process primarily employs gravity casting technology. In this method, the molten aluminum alloy is poured into a gating system and then steadily fills the cavity of a sand mold, metal mold, or other type of casting model—driven solely by gravity. After natural cooling and solidification, the final cast component is formed. The typical process includes steps such as mold preparation, alloy melting, pouring, cooling, shakeout, and cleaning.
Product Features
- The process has broad adaptability: it demonstrates relatively strong resilience to variations in part dimensions and wall thickness.
- Mold costs are relatively low: particularly in single-piece or small-batch production scenarios, they offer a distinct cost advantage.
- The product has low internal stress: Due to the relatively gradual cooling rate, residual stresses in the castings are typically minimal.
- The range of castable materials is quite broad: it is suitable for various series of aluminum alloy materials.
- Good molding flexibility: Capable of producing parts with relatively complex shapes or larger volumes.
- Mechanical performance remains stable: With proper heat treatment processes, its mechanical properties can be significantly improved.
Application Areas
This type of casting is suitable for applications where mechanical properties and structural integrity are critical, but the demand for surface finish and production efficiency takes a backseat to die-casting processes—such as:
- General-purpose machinery: gearbox housings, pump casings, hydraulic valve bodies, and more.
- Automotive industry: engine cylinder heads, wheel hubs, large structural components, and more.
- Electrical equipment: motor end covers, insulator flanges, distribution box bodies, and more.
- Other fields: It is also applied in medical device and model mold manufacturing.
