What Is Superalloy Vacuum Investment Casting Technology? Precision Wax Pattern Formation: High-accuracy wax injection into precision-machined molds replicates aerospace geometries with ±0.02 mm tolerance, ensuring consistency for downstream casting. Ceramic Shell Mold Development: 6–8 layers of ceramic slurry and refractory sand form durable molds capable of withstanding ~1450°C casting temperatures. Controlled Dewaxing Process: Autoclave dewaxing at ~150°C removes wax while maintaining mold integrity and dimensional stability. High-Temperature Mold Firing: Firing at ~1000°C eliminates contaminants and stabilizes mold structure for aerospace-grade components. Vacuum Melting of Superalloy: Vacuum melting at ~1450°C (10⁻³ Pa) ensures metallurgical purity, controlled composition, and reduced inclusions. Controlled Casting and Solidification: Optimized solidification produces fine-grain microstructures (≤1 mm), […]
