Tool Design and Manufacture
A wax injection mold is designed and built to produce castings per customer specifications.
A wax pattern of recyclable material is produced from the wax injection mold.
High Volume Production
Multi-cavity tools are used to expedite the volume of wax production.
Thompson Investment Casting’s unique method of gating and treeing systems assures sound castings at a minimum cost.
The pattern assembly is systematically dipped into a ceramic slurry, coated with a refractory material and dried. The process is repeated until the desired thickness and strength is achieved.
Ceramic Shell Drying
Between coatings, the ceramic shells are dried in an atmospherically-controlled environment.
Using regulated steam pressure, an autoclave melts and reclaims the wax from the ceramic shells.
High temperature ovens cure and preheat the ceramic shells prior to pouring the molten metal.
Pre-heated molds are poured utilizing a unique process which facilitates the production of thin walls and intricate detail while enhancing the surface.
Knock Out & Cut Off
The ceramic shell is removed, the cluster is cleaned, & the castings are cut free from the gating system.
Machining & Finishing
After cut off and gate removal, all secondary finishing operations are performed.
Inspection & Testing
Castings are inspected & precisely tested according to customer specifications and requirements.
