All materials are supplied with full heat traceability and certified chemical composition (AMS / ASTM standards).

Our investment casting process is scalable to both precision small components and medium-to-large turbine structural parts.

» Casting weight: from a few grams up to 100 lbs (45 kg) or higher depending on geometry and alloy system
» Minimum wall thickness: 0.040" – 0.080" (application dependent)

» Linear dimensional tolerance:

•     Up to 1": ±0.005"
•     Above 1": ±0.003" incremental tolerance

Process simulation and controlled solidification techniques are applied for complex geometries to ensure casting integrity, shrinkage control, and dimensional stability.

Investment casting is widely used in turbine systems due to its ability to produce complex, high-performance geometries.

Key advantages:

    » Internal cooling channels and thin-wall structures
    » Near-net-shape manufacturing reduces machining requirements
    » High dimensional repeatability for serial production
    » Excellent surface finish for aerodynamic efficiency
    » Compatibility with high-temperature superalloys
    » Part consolidation and reduced assembly complexity

Our production system is certified to ISO 9001 quality management standards, with full process traceability.

Quality control includes:

        Heat number traceability for all superalloys
        Controlled wax pattern and ceramic shell processes
        Dimensional inspection using precision metrology
        Non-destructive testing (NDT) upon request
        Full inspection and batch documentation
