Why Choose Investment Castings

The Investment Casting Process

Investment castings are a great way for Small to Medium-sized businesses to get affordable castings within a short time frame. These steps create quality parts from start to finish.

1

A toolmaker builds a precision aluminum die to make wax replicas of the part, called patterns.

2

Molten wax is injected into the die cavity; the resulting pattern is removed after it solidifies.

3

From one pattern to as many as two hundred are wax welded to a wax runner to form a cluster.

4

The cluster is dipped repeatedly in liquid binder and ceramic powder to build up a shell mold.

5

The mold is placed in an autoclave to melt out the wax, then in a furnace to harden and preheat it.

6

Molten steel is poured into the heated mold, and solidifies to form a cluster of castings.

7

The mold material is removed from the cluster, and the parts are sawed off from the runner.

8

The parts are finish-ground, deburred, and sent for secondary operations such as heat treating.

9

Each part is inspected and shipped on time – guaranteed to meet your specifications.
