Investment Casting

Contact Trident Resources

The Investment Casting process begins with producing a heat disposable pattern. This is accomplished by injecting wax or plastic into a metal die. A pattern must be molded for every casting. These patterns are assembled into a cluster (or tree) and are then coated with various liquid ceramic refractories to form a ceramic shell. By using a wax impression mold, elaborate tooling can be avoided when producing parts with unusual designs or with complex internal configurations. Small, intricate, or hard-to-machine shapes can be produced much more efficiently with the investment casting process.

Often several machined parts may be combined into one casting, eliminating or greatly reducing other labor-intensive operations such as welding, assembly, and finishing work.

Because each part is formed from the same master mold, each finished part is virtually identical. For many parts, you can achieve higher quality, more detail, greater consistency and better repeatability than traditional metal forming methods. Aluminum investment castings and Copper investment castings can be offered as a cost effective bridge between sand casting and die casting.

Any number of different alloys can be cast into the ceramic mold. After cooling, the ceramic shell is removed and the castings are cleaned.

Investment castings in most air melt alloys including 300 & 400 stainless steels, copper base, nickel base, cobalt base alloys, as well as carbon and high alloy steel grades.

Investment castings are ideally suited for both long and short runs and Trident's cost effective tooling programs make this a less capital-intensive metal process.
