Investment casting is a manufacturing process in which a wax pattern is coated with a refractory ceramic material. Once the ceramic coating material is dry and hardened, the wax is melted out and leaves an internal cavity the shape of the final product’s geometry. Molten metal is poured into the cavity where the wax pattern was. The metal solidifies within the ceramic cavity, cools, and the ceramic is removed from the metal casting. The result of this process is a net to near-net precision metal component which can be used for a broad range of applications in various industries.

Why is it Called Investment Casting?

The ancient art and science of investment casting is also known as the lost wax process. Investment casting was developed over 5500 years ago and can trace its roots back to both ancient Egypt and China. Parts manufactured in industry by this process include dental fixtures, gears, cams, ratchets, jewelry, turbine blades, machinery components and other parts of complex geometry.

What Materials can be Investment Cast?

The advanced quality materials we most commonly use, include:

·Stainless Steel	Steel	Ductile Iron	Beryllium Copper	Nickel-Based	Aluminum	Cobalt-Based	Copper-Based

What is Investment Casting Used For?

The investment casting process is most beneficial for casting metals with high melting temperatures that cannot be forged, pressure casting, or molded in plaster or sand. Typical investment castings include parts with complex geometries, such as turbine blades, firearm components, marine parts, and other industrial components.

 

What are the benefits of Investment Casting?

There are many benefits associated with investment casting in the manufacturing of precision metal components, some of which include:

· Mold design versatility

· Increased complex design capabilities

· Provides for a smoother surface (125 RMS)

· Highly accurate, repeatable-designs

· Time & cost savings versus fabrication and machining

· Produces numerous types of products

· Numerous types of metal alloys can be used
