Of Sand Cores For The Foundry Industry & Molded Sand Products


Located in Millersburg, TH Manufacturing offers a complete line of Binder Systems including Shell, Warm Box, Cold Box, and Airset.

The "experts" keep telling us that the U.S. is evolving into a Service Economy. They say that manufacturing is dead. They even suggest that we accept that foreign countries with cheap labor will cast all of our parts and we'll just buy whatever they make.

Well, they're wrong. Welcome to TH Manufacturing.
