From defense and industrial equipment to jewelry and consumer goods, investment casting stands as a vital manufacturing solution, delivering high-quality and intricately designed parts for a wide array of applications throughout the manufacturing spectrum.

The Intricate Process of Investment Casting

Understanding the steps involved in Custom Investment Casting provides insight into the craftsmanship behind this technique.

Wax Pattern Creation

The process begins with the creation of a wax pattern, capturing the fine details of the final component.

Shell Building

The wax pattern is then coated with a ceramic shell, creating a mold that will withstand the rigors of the casting process.

Melting and Pouring

The mold is heated to remove the wax, leaving behind a cavity ready for the molten metal. The metal is then poured into the mold.

Cooling and Removal

After the metal solidifies, the shell is broken, revealing the final cast component. Precision and accuracy are paramount at every stage.custom investment casting 4

Types of Materials for Investment Casting
