Investment Casting Applications
May 21,2025
Core components: Turbine blades (single crystal high temperature alloy blades, the complexity of the internal cooling structure reaches the micron level). Engine casing (integrated structure, reducing 300+ assembly welding points, improving reliability).
1. Aerospace: The "lifeline" of precision parts
Core components:
Turbine blades (single crystal high temperature alloy blades, the complexity of the internal cooling structure reaches the micron level).
Engine casing (integrated structure, reducing 300+ assembly welding points, improving reliability).
Technology trend: vacuum melting + directional solidification technology, used to manufacture aircraft engine combustion chambers, the temperature resistance is increased from 1100℃ to 1300℃.
2. Medical equipment: the perfect combination of personalization and high precision
Artificial implants:
Based on CT data 3D printing wax model, titanium alloy knee joint prosthesis matching the patient's bone structure is made, and the operation time is shortened by 40%.
Porous structure bone nails (porosity 40%-60%, promoting bone cell growth), realized by investment casting + powder metallurgy composite process.
Surgical instruments: The complex hinge structure of stainless steel surgical forceps, one-time molding without assembly, surface roughness Ra≤1.6μm meets the sterility requirements.
3. Energy equipment: key processes for extreme environment resistance
Nuclear power: austenitic stainless steel valves (pressure level Class 2500), with smooth inner wall flow channels achieved through investment casting, reducing fluid resistance by 30%.
Petrochemical: corrosion-resistant impellers made of nickel-based alloy (Inconel 625) can serve for more than 10 years in hydrogen sulfide-containing media.
4. High-end manufacturing and art
3C products: titanium alloy wearable device cases (such as the precision crown structure of Apple Watch), with 0.2mm wall thickness and mirror polishing effect achieved through investment casting.
Art casting: Bronze sculptures (such as large city statues) use the lost wax method to replicate the details of the artist's original manuscript, avoiding the problem of blurred edges and corners in sand casting.
