Company Overview
A part of Howmet, Georgetown Casting is a major provider of aluminum and copper-based castings for the aerospace and commercial industries. Georgetown Casting has been a part of Howmet since 1989.
Howmet Georgetown Casting specializes in small, extremely complex castings. Located in Georgetown, Ontario, Canada, the plant occupies 36, 000 square feet of manufacturing space and employs more than 100 people. Producing aluminum and copper-base alloy castings, using both the shell and solid mould process, Georgetown Casting has developed unique capabilities for producing complex cored castings. Georgetown Casting produces high-volume lots of small to medium size castings mainly for the commercial aerospace industries.
Howmet has long been a world leader in the manufacture of precision super alloy and titanium investment castings, primarily for jet aircraft and other gas turbine engines. All of the group members have in-house capabilities, which include heat treating, chemical analysis, mechanical testing, penetrant and radiographic inspection, and CAD facilities. All three North American operations are networked together using the Casting Excellence programs, resulting in a totally standard set of capabilities available to all customers. These include bar coding, EDI, email, advanced shipment notification, on-line quality manual (available on diskette), and an FTP site for a more efficient transfer of electronic files.
In its quest for administrative and technical excellence, all four operations of the Howmet Casting Group have become ISO 9002 approved. It is a tribute to an extremely dedicated team of foundry personnel striving to meet all of its customers' needs.

Technology: The Forming Process
Step 1: The process begins with production of a one piece pattern. This pattern is usually made by injecting wax into an aluminum die. These dies may range from a simple hand operated single cavity tool to a fully automated multi cavity tool, depending on quantities and complexity.
Step 2: Patterns are fastened by the gates to one or more runners. The runners are attached to the pouring cup. Both are usually made of wax. Patterns, runners and pouring cup comprise the cluster or tree, which is needed to produce the ceramic mold.
Step 3: The investment shell technique involves dipping the entire cluster into a ceramic slurry giving the cluster its initial face coat.
Step 4: After drying, the cluster is coated again and again using progressively coarser grades of ceramic material, until a self-supporting shell has been formed. The shell may run between 3/16 to 5/8 inches thick.
Step 5: This is a sectioned view of the shell prior to the de- waxing process.
Step 6: The coated cluster is placed in a high temperature furnace or steam autoclave where the pattern melts and runs out through the gates, runners and pouring cup. This leaves the foundry with a ceramic shell containing cavities of the casting shape desired with passages leading to them.
Step 7: The molds must be fired to burn out the last traces of pattern material and to attain a certain degree of permeability before they can be filled with metal. In the case of solid molds, this heating has to proceed slowly, in a controlled cycle which stretches over 12 to 18 hours to avoid cracking.
Step 8: Molten Metal is poured into the fired shell at temperatures exceeding 1000 degrees Fahrenheit which varies depending on the type of alloy.
Step 9: After the poured metal has cooled, the mold material is removed from the casting cluster using high pressure water. This image illustrates a complete cluster just after the mold or outside shell has been removed.
Step 10: The individual castings are removed from the cluster and any remaining protrusions left by gates or runners are removed by grinders. Generally the castings are sand blasted for a smoother finish. The castings are then ready for secondary operations.
