The Investment Casting Process

Investment castings are a fantastic way for Small to Medium-sized businesses to get affordable castings within a fleeting 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.
