Aluminum investment casting, also known as lost wax casting, is a precision manufacturing process that involves creating intricate and complex aluminum components through the use of sacrificial wax patterns. This process allows for high dimensional accuracy and intricate detailing in the final aluminum product.
The casting capacity of WELLE manufacturers including process, material, weight and size is listed as follows:
✧ Casting Process: Vacuum Casting, Investment Casting, Centrifugal casting, Lost Foam Casting, Die Casting, NDT (Non-Destructive testing), Heat-treatment, Welding.
✧ Casting Material: Nickel-Base Alloys, Alloy Steel, Inconel Alloy, Stainless Steel, Copper, Bronze, Aluminum Series, Cast Iron, SG Iron, other materials are available upon request.
✧ Casting Weight: 0.02kg – 2,000kg
✧ Size: 5mm – 3000mm
Process:
- Pattern Creation: A wax pattern, precisely replicating the desired part, is produced.
- Assembly: Multiple wax patterns are assembled onto a gating system to form a cluster.
- Shell Building: The wax cluster is coated with ceramic shells through a series of dipping and coating processes.
- De-waxing: The ceramic-coated cluster is heated to remove the wax, leaving behind a mold cavity.
- Casting: Molten aluminum is poured into the preheated mold cavity.
- Cooling and Finishing: The aluminum solidifies, and the final product is removed, undergoes post-casting treatments, and is finished.
