About Us

    TH Manufacturing Inc. is the legacy business of a small foundry started in 1975 in Holmes County, Ohio. Berlin Castings focused on wood stove components and agricultural equipment tailored to the local Amish community. The business climate of the early 90’s proved too much for the small foundry and it closed abruptly in May of 1992.

    Enter two young men with a history in foundry engineering and operations who decided to re-open it in June of 1992, calling it TH Manufacturing. It became apparent that we needed to make some radical changes if the business was to survive. We had some experience making Shell Cores and were successful in convincing McConway Torley Corporation in Pittsburgh that we could make pouring cups for them.

    We slowly leveraged our opportunities to make Shell Cores for other local foundries and  expanded into Cold Box cores, and No-Bake molds and cores. Within a few years we decided to close the foundry and concentrate on core making exclusively.

    Due to low cash flow and an uncertain future, we started making our own core machines. The manufacturing of custom core machines continues to this day. Our customers present us with a wide range of tooling types that often cater to a certain type of machine. Our machines are built to adopt all tooling types, saving our customers excessive rigging fees and allowing quick turnaround of new tooling into quality cores.

     Our Amish workforce contributes strongly to the success of our business. The initial group of Amish core makers branched out to become subcontractors, operating their own core shops. After nearly 30 years in business, they have accrued a wealth of knowledge in core-making, and their work ethic is second to none.

    I have worked in Manufacturing since 1978. I witnessed (and was negatively affected by) the rush to globalization that started in the late 50’s but picked up steam in the mid-70s. I watched as business after business was shuttered while large corporations chased cheap labor around the globe with the tacit approval and encouragement of the federal government. The talking heads on TV said the US would become a “Service Economy” and that “Dirty” manufacturing should not be done on US soil. I did not accept that premise then and I do not accept it now.

    I believe there is a renaissance in US Manufacturing underway due to the combined effects of Covid and geopolitical change worldwide. I am optimistic that we can regain US Manufacturing preeminence without sacrificing our health or our environment. Manufacturing can provide employment and a good living for hundreds of thousands across our nation and help to promote a stronger domestic economy. Count me Pro Manufacturing!
