I. Aerospace

In aircraft engines, investment casting demonstrates irreplaceable technical advantages:


  • GE9X single-crystal turbine blades: Made from nickel-based superalloy CMSX-4 with 95% columnar grain structure via directional solidification, capable of stable operation over 10,000 flight cycles in 1200℃ gas environments.

  • Combustion chamber liners: MCrAlY-coated cobalt-chromium alloy with CT4 precision (±0.15mm/25mm) ensures gas sealing and thermal fatigue resistance.

II. Medical

Medical implant manufacturing demands extreme material purity and surface properties:


  • Cobalt-chromium hip implants: Achieve 99.99% metal purity via vacuum casting, with porous Ti plasma spray surfaces (Ra1.6μm) promoting bone cell growth and 900MPa tensile strength (3x human bone).

  • Titanium spinal implants: Direct casting creates trabecular structures matching natural bone density, avoiding machining-induced stresses.

III. Industrial Equipment

In harsh industrial environments, investment casting excels in temperature/corrosion resistance:


  • Hastelloy C-276 valves: Integrally cast for 200℃ sulfuric acid resistance with <0.01mm/year corrosion rate, reducing welding requirements through one-piece flange design.

  • Nickel-aluminum-bronze propellers: 0.5mm thin-wall structure optimizes hydrodynamic performance, achieving 50,000+ fatigue cycles in offshore platforms.

IV. Luxury Goods

In luxury manufacturing, investment casting combines artistry with functionality:


  • 18K gold jewelry settings: Lost-wax casting forms 0.1mm diamond prongs with 95% material utilization and Ra0.8μm mirror finishes.

  • Stainless steel watch cases: One-piece 316L alloy casting provides 100m water resistance while enabling skeletonized movement designs.

V. Energy Sector

For clean energy equipment, investment casting delivers critical support:


  • Nuclear reactor components: Zirconium alloy castings withstand 300℃ coolant and radiation environments, with integrally formed fuel rod guide tubes ensuring operational safety.

  • Wind turbine bearings: High-strength steel castings with internal lubrication channels maintain reliability across -40℃ to 50℃ temperature ranges over 10 million cycles.

Why Choose Investment Casting?

Unique advantages include:
✅ Complex geometries: Internal channels impossible with other methods
✅ Material purity: 99.99% metal purity via vacuum casting
✅ Surface finishes: Direct casting achieves medical-grade (Ra1.6μm) and consumer-grade (Ra6.3μm) standards
