Shell Moulding

Precision Shell Molding by Vodash Engineering

Vodash Engineering specializes in shell molding, a precision casting process renowned for producing metal components with exceptional surface finishes and tight dimensional tolerances. Our expertise in this advanced technique allows us to create intricate parts with minimal post-processing, ensuring high-quality results for demanding applications.


Advantages

  • Excellent Surface Finish: This significantly reduces or eliminates the need for secondary machining operations, saving time and cost in manufacturing.

  • High Dimensional Accuracy: Tighter tolerances achieved through shell molding lead to more precise parts, improving assembly and overall product quality.

  • Intricate and Thin-Walled Castings: Enables the production of complex geometries and lighter components that may not be feasible with traditional sand casting.

  • Reduced Casting Defects: The nature of the shell mold minimizes issues like gas defects and sand inclusion, resulting in higher yield and fewer rejects.

  • Good Productivity for Medium to High Volumes: The ability to create multiple molds from a single pattern and potential for automation makes it efficient for serial production.
