Investment Casting Process

Our investment cast process follows a controlled and systematic approach, from wax pattern creation to final inspection, ensuring dimensional accuracy, material integrity, and consistent quality for ferrous and non-ferrous components.

  • Wax Mould Press Shop

    Wax Mould Press Shop

    Wax patterns are produced using precision moulds to achieve accurate shape and dimensions. This stage ensures consistency, surface detail, and repeatability for high-quality investment cast components.

  • Coating Shop

    Coating Shop

    Wax patterns are coated with ceramic slurry and sand to build strong shells. Controlled coating layers help achieve smooth surface finish and dimensional stability during metal pouring.

  • Dewaxing

    Dewaxing

    The ceramic shells undergo a controlled dewaxing process to remove wax completely. This creates a clean internal cavity ready for molten metal casting without distortion.

  • Melting & Pouring

    Melting & Pouring

    Metals are melted under controlled conditions and poured into prepared ceramic shells. Careful temperature control ensures material integrity, strength, and uniform metal flow.

  • Heat Treatment

    Heat Treatment

    Cast components undergo heat treatment to achieve required mechanical properties. This process improves strength, hardness, and durability based on material specifications.

  • Fettling Shop

    Fettling Shop

    Excess metal, gates, and runners are removed through fettling operations. This stage improves shape accuracy and prepares castings for further finishing processes.

  • Casting Inspection

    Casting Inspection

    Each casting is inspected for dimensional accuracy and visual quality. Inspection ensures compliance with drawings, specifications, and required quality standards.

  • Machining

    Machining

    Precision machining is carried out to achieve final dimensions and tolerances. CNC turning and milling ensure accurate and repeatable results.

  • Final Inspection

    Final Inspection

    Finished components undergo final quality checks before dispatch. This ensures dimensional accuracy, surface finish, and overall compliance with customer requirements.
