Basic Information:
  • Innovations in Materials and Processes

    Recent advancements in investment casting focus on improving efficiency, precision, and sustainability:

    Advanced Ceramic Shells: The adoption of colloidal silica binders (e.g., SKP-27) enhances shell strength and reduces drying time, minimizing defects like veining or shell cracking.

    Automation: Automated systems for wax injection, shell coating, and quality inspection streamline production. Robotic sanding and CNC machining further reduce human error.

    Simulation Software: Tools like CAE simulate mold filling and solidification, predicting defects such as shrinkage porosity or hot tears. This reduces trial-and-error cycles.

    Case Study: Titanium Alloy Casting
    Titanium’s reactivity demands specialized techniques. Vertical centrifugal casting is employed to minimize gas entrapment and improve microstructure uniformity. Post-casting treatments, such as hot isostatic pressing (HIP), enhance mechanical properties for aerospace applications.

    Sustainability Measures

    Sand Reclamation: Reusing ceramic sands reduces waste and costs.

    Low-Emission Binders: Water-based binders replace toxic chemicals, aligning with environmental regulations.
