Investment Casting Process Description
Investment casting, also known as lost-wax casting, is a process in which a wax pattern is coated with a ceramic material to create a mold. Once hardened, the wax is melted away, leaving a cavity into which molten metal is poured. The process produces components with excellent dimensional accuracy, intricate geometries, and smooth surface finishes.
Redstone’s investment casting foundry in india partners use advanced technologies including:
- Wax pattern production for precise component replication
- Ceramic mold creation for complex shapes
- High-temperature metal pouring and controlled cooling
- Mold removal, finishing, and machining operations
- Quality inspections for dimensional accuracy and material properties
This method ensures highly detailed, near-net-shape castings suitable for critical applications.
