HISTORY: Founded in 1969 by Jack D. Thornton under the name Jax Mold and Machine in Ontario Canada. Jack created a standard for the industry. This standard has been passed down through two generations.

Jack had four sons that have carried on the business, two of whom are currently very involved, Paul and Tom. Tom has two sons that are stepping in the same footprint that was made years ago.

There are three locations in the U.S.A; Caliber Mold and Machine in Akron, Ohio, TeNac INC in Morrison, Tennessee, and Athens Mold and Machine in Athens, Ohio. All of which are proud to be family and American owned.
