INVESTMENT CASTING

Precision investment casting solutions crafted for aerospace, automotive, medical, and industrial sectors. Combining intricate design capabilities, exceptional accuracy, and superior material performance to drive innovation in modern manufacturing.

Why Choose Investment Casting?

Investment casting is a preferred manufacturing method for producing high-precision, complex metal components with excellent surface quality.

Exceptional Precision & Complex Designs

Our investment casting process delivers intricate shapes, thin walls, and detailed features with exceptional dimensional accuracy, reducing or eliminating the need for machining making it the perfect choice for aerospace and automotive applications.

Superior Surface Finish & Material Versatility

Delivers a smooth surface finish, minimizing post-processing while supporting a wide range of metals, including stainless steel, titanium, and nickel-based alloys for high-performance applications.

Cost-Effective for Small to Medium Production

Minimizes material waste and machining costs, making it ideal for low to medium production runs while ensuring efficiency and high quality.

Investment Casting Process

Investment casting, also known as lost-wax casting, is a precise and versatile manufacturing process used to produce complex metal components with excellent surface finish and dimensional accuracy.

  • 1. Pattern Creation

    A wax model (pattern) of the desired part is created using injection molding or 3D printing. This pattern is an exact replica of the final component.

  • 2. Pattern Assembly

    Multiple wax patterns are attached to a central wax sprue (tree-like structure), allowing multiple parts to be cast simultaneously.

  • 3. Shell Building

    The wax assembly is repeatedly dipped in a ceramic slurry and coated with fine sand to create a strong ceramic shell. Each layer is allowed to dry before applying the next, building a thick, heat-resistant mold.

  • 4. Wax Removal (Dewaxing)

    The ceramic-coated wax assembly is heated in an autoclave or furnace, causing the wax to melt and drain out, leaving a hollow ceramic mold.

  • 5. Mold Firing

    The empty ceramic mold is fired at a high temperature to remove any residual wax and strengthen the shell, making it ready for metal pouring.

  • 6. Metal Pouring

    Molten metal (such as stainless steel, aluminum, or titanium) is poured into the preheated ceramic mold. The metal fills the hollow cavity left by the wax pattern.

  • 7. Cooling and Solidification

    The molten metal cools and solidifies inside the mold, forming the final shape of the component.

  • 8. Shell Removal

    Once the metal has fully solidified, the ceramic shell is broken away using mechanical or chemical processes, revealing the rough casting.

  • 9. Cutting and Finishing

    The individual cast parts are cut from the sprue, followed by finishing processes such as grinding, machining, heat treatment, and surface coating to achieve the required specifications.
