Initially, a wax pattern is coated with a refractory ceramic material, which hardens to form the internal geometry of the desired casting.

The wax is then melted out, creating a cavity that is filled with molten metal. After solidification, the metal casting is removed from the ceramic mold.

This process, with its origins dating back over years to ancient Egypt and China, finds applications in various industries, including dental fixtures, gears, jewelry, turbine blades, and machinery components.

The investment casting process begins with the fabrication of a wax pattern, which can also be made from plastic but is commonly made from reusable wax due to its easy removal.

As the pattern is destroyed during the process, a new pattern is required for each casting.

When producing parts in large quantities, a mold is used to manufacture the patterns. Similar to the molds used in expanded polystyrene casting, these molds for wax patterns can be cast or machined.

The careful calculation is necessary to determine the size of the master die, taking into account the shrinkage of wax, the ceramic material, and the metal casting, which can lead to some trial and error and increased costs.

The advantage of investment casting lies in its ability to manufacture castings with intricate and complex geometries since the mold does not need to be opened.

Multiple wax patterns can be combined or connected to a central sprue, forming a tree-like arrangement.

The patterns are then coated with a refractory slurry composed of fine-grained silica, water, and binders.

The ceramic layer is built up by repeated dipping or pouring over the pattern.

Once the ceramic coating is sufficiently thick, it is dried and hardened.

The next crucial step involves heating the mold to a specific temperature, causing the wax to melt and flow out, leaving behind the cavity for the metal casting.

The ceramic mold is further heated to strengthen it, remove any remaining wax or impurities, and drive out moisture.

The hot mold enables smooth flow of the molten metal, ensuring detailed and accurate castings. After pouring, the casting solidifies within the mold.

Finally, the ceramic mold is broken, and the parts are separated from the tree.

Investment casting offers several advantages, including the ability to produce complex parts with excellent surface finish, thin sections as narrow as .015 inches (.4mm), and high dimensional accuracy with tolerances as low as .003 inches (.076mm). It can accommodate a wide range of metals and alloys, even those difficult to machine or fabricate.

The process allows for automation in certain stages, but it is considered relatively expensive and complex.
