Product Description

The Investment Casting Process

investment casting use a technique known as a lost wax process, one of the oldest manufacturing techniques in the history of humankind. While the principles remain the same, modern steel investment casting uses intricate parts and machine components. A typical investment casting process involves:

  • Creating a pattern: Manufacturers use a computer modeling program to make a three-dimensional solid model. They then use stereolithography, a type of 3-D printing process, to transform the virtual model into one made of wax or a different material that melts.

  • Mold making: Workers dip the wax pattern into refractory slurry several times to form a skin over the wax mold. For low-temperature melts, the slurry generally contains plaster of Paris (binder) and powdered silica (refractory). Higher-temperature melts use silica (binder) and sillimanite (refractory). Depending on the fineness of the desired finish, workers apply additional coatings of ethyl silicate and sillimanite. When a casting is heavy, specialists might place the mold in a large container and reinforce it with more slurry.

  • Mold heating: Workers heat the pattern in an oven to melt away the wax.

  • Mold preheating: Workers preheat the mold to about 1,000°C to remove any remaining wax, harden the binder, and ensure the mold completely fills with molten metal.

  • Metal pouring: Pouring methods include using gravity, as well as pressure or vacuum conditions.

  • Inspections: A specialist ensures the casted part is identical to the original design and contains no damage or weakness.

Investment Casting Applications


The aerospace industry heavily relies on investment casting to create items such as satellites, aircraft door frames, hydraulic fluid system components, actuation systems, bearing cages, cargo systems, and landing and braking components.

Power generation: 

Turbine blades, fuel nozzles, seal hardware, airboxes, combustion hardware, and turbulation tubes are made using investment casting.


The military uses investment casting for a variety of applications, including robotics, firearm manufacturing, missile components, electronic housings, armored vehicles, shipboard components, sonar and radar receivers, and heavy armament components.


Auto manufacturers use custom investment casting for unique and aftermarket parts, tools and accessories.
