Aluminium Casting
Aluminium Casting:
Aluminium Casting is a versatile process used to shape molten aluminium into precise and functional components. At CSG Extrusion LLC, we specialize in high-quality aluminium casting for various industries including automotive, aerospace, construction, and more.
Common Aluminum Casting Methods
1. Die Casting
2. Sand Casting
3. Investment Casting (Lost Wax)
4. Permanent Mold Casting
5. Centrifugal Casting
6. Gravity Die Casting
7. Vacuum Casting
Factors to Consider in Aluminum Casting
1. Part Complexity
Intricate shapes: Investment or die casting
Simple designs: Sand or gravity casting
2. Production Volume
High volume: Die casting
Low volume: Sand or investment casting
3. Accuracy & Surface Finish
Best finish: Die and investment casting
General use: Sand casting
4. Size of Components
Large parts: Sand or permanent mold casting
Small precision parts: Die or investment casting
5. Mechanical Properties
High strength: Vacuum or centrifugal casting
Standard performance: Most casting methods
6. Budget
Low-cost options: Sand casting
High-value at scale: Die casting
Applications of Aluminum Casting
Automotive: Engine blocks, gear housings (Die Casting).
Aerospace: Turbine blades, structural parts (Investment, Vacuum Casting).
Construction: Brackets, beams (Sand Casting).
Electronics: Housings, heat sinks (Die Casting).
Machinery: High-stress components (Centrifugal or Permanent Mold Casting).
