What is investment casting and why is it the ideal choice for demanding castings?

Investment casting is an advanced manufacturing technology that enables the production of complex castings with high dimensional accuracy and a smooth surface finish. This process is ideal for parts that cannot be easily machined or require minimal additional processing.

How does the investment casting method work?

The process starts by creating a wax pattern, which is an exact replica of the final casting. This wax model is coated with a ceramic shell that hardens to form the mold. The wax is then melted out, and molten metal is poured into the cavity. Once the metal solidifies, the ceramic mold is removed to reveal the final casting.

Advantages of investment casting:

• Shape diversity – allows the production of very complex geometries.
• High casting accuracy – minimizes the need for additional machining.
• Wide range of materials – suitable even for difficult-to-machine alloys and special metals.
• Quality surface finish – castings have a fine structure without extensive post-processing.

Thanks to these properties, investment casting is the ideal choice for producing demanding components in aerospace, automotive, energy, and other industries.
