What is Vacuum Investment Casting?

Vacuum investment casting is a high precision moulding process wherein molten metal casting is poured under controlled vacuum atmosphere into a ceramic shell. By minimizing air pockets and gas porosity, it offers superior surface finish and exceptional detail on themost complex, thin walled parts. This process is particularly effective for casting advanced alloys like Inconel and Hastelloy, often used in aerospace, turbine engines, and medical devices. With its ability to produce intricate designs and tight tolerances, it is ideal for critical applications that demand both strength and precision.

Why Use Vacuum Investment Casting?

By utilizing a vacuum environment, vacuum investment sasting offers the ability to cast high-performance alloys like Inconel and Hastelloy, ensuring minimal porosity and exceptional surface finish for complex parts.
