What is Precision Investment Casting?

Precision investment casting, also known as precision casting, is a lost wax casting process used to make parts from ferrous and non-ferrous metals. By “lost wax casting,” we mean that metal parts are created from a wax mold.

The precision investment casting process starts with you designing and fabricating a wax injection moldㅡwhich is used to create a wax pattern having the same geometrical shape as the desired finished part. Depending on the complexity of your design, you might have to create a single wax pattern or as many as twenty wax patterns. The goal here is to have patterns that form the geometrical shape of the intended finished cast part when assembled.

Next, the assembled wax pattern is dipped into a ceramic slurry until a ceramic mold is formed. The ceramic mold is then preheated before being filled with molten metal, allowed to set, and broken off to form the desired metal cast.

Why Precision Investment Casting?

Precision casting offers several advantages over other manufacturing processes. For instance, the process eliminates the material wastage challenge common in subtractive manufacturing technologies like CNC machining, allowing you to reduce manufacturing costs. It also reduces the long production time common in metal fabrication processes like welding.

In addition, precision casting allows you to fabricate complex parts that might be challenging to create using CNC machines. So, suppose you’re looking to fabricate complex internal passages in a metal part, curved vanes of an impeller, or cooling channels in complex devices with great surface finishes. In that case, you must consider using precision investment casting.

Precision forging also allows you to create complex shapes, like the precision investment casting process. However, because the forging process requires specially designed tool dies, the associated tooling costs are higher than in precision casting. Additionally, precision casting offers greater design freedom, allowing you to produce larger and more complex geometries than other manufacturing technologies.
