A commercial austempering company, since 1976.
One of the largest commercial austempering companies in the U.S. — built around a single process, run from a single plant in Logansport, Indiana, around the clock.
One process. Done at the highest level.
HTI has done one thing since 1976: austempering. Where general heat treaters spread across dozens of processes, HTI built an entire company around mastering a single one — and became one of the largest commercial austempering companies in the United States along the way. Everything runs from one plant in Logansport, Indiana, where four continuous belt furnaces operate around the clock. Today HTI operates as part of the MPI Corp family of companies.
