Titanium alloys offer exceptional strength-to-weight ratios, corrosion resistance, and biocompatibility, making them ideal for aerospace, medical, automotive, and chemical industries. Neway AeroTech specializes in precision vacuum investment casting of high-quality titanium components, including Ti-6Al-4V (TC4) and Ti-6Al-4V ELI, ensuring strict adherence to industry standards and demanding application requirements.
Leveraging advanced manufacturing processes and meticulous quality controls, we provide precision titanium components that meet stringent tolerances and performance criteria.
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.
Precise wax patterns created to replicate final component geometry within ±0.05 mm tolerance.
Ceramic shells built layer-by-layer (8–12 mm thick) capable of enduring molten titanium (~1700°C).
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.
Ceramic shells removed mechanically or chemically.
Precision CNC machining finalizes dimensions to exact tolerances (±0.1 mm), ensuring ideal fits for critical assemblies.
