Core Challenges in Titanium Alloy Casting
Casting titanium components involves distinct challenges, including:
High Reactivity: Titanium alloys require inert or vacuum environments (<0.1 Pa) to avoid contamination and oxidation at casting temperatures (~1700°C).
Dimensional Accuracy: Achieving stringent dimensional tolerances (±0.1 mm) essential for precision assemblies and critical functional components.
Microstructure Control: Ensuring uniform grain structure to deliver optimal mechanical performance and consistency.
Surface Quality: Providing smooth surfaces (Ra 1.6–3.2 µm) to meet rigorous performance standards.
Detailed Titanium Casting Process
Wax Pattern Production
Precise wax patterns created to replicate final component geometry within ±0.05 mm tolerance.
Ceramic Shell Mold Formation
Ceramic shells built layer-by-layer (8–12 mm thick) capable of enduring molten titanium (~1700°C).
Vacuum Melting & Casting
Vacuum melting performed under controlled conditions (<0.1 Pa) ensures titanium alloy purity and prevents contamination.
Controlled casting provides uniform material properties and defect-free precision components.
Finishing and Precision Machining
Ceramic shells removed mechanically or chemically.
Precision CNC machining finalizes dimensions to exact tolerances (±0.1 mm), ensuring ideal fits for critical assemblies.
