Master Induction Heat Treat LLC

Master Induction Heat Treat, LLC is an induction hardening facility located in LaPorte Indiana.  Master Induction Heat Treat, LLC is a wholly owned subsidiary of the Mayfield-Glenn Group, Inc.  The Mayfield-Glenn Group began doing business as Master Roll Manufacturers in 1998 in LaPorte, Indiana.  The business has grown here in LaPorte for over a decade.

In late 2011, corporate officers identified heat treating bars in the lengths over 36' to be a bottleneck in the roll manufacturing facility.  As a result, the decision was made to purchase induction equipment and begin to provide induction hardening services to sister company Master Roll Mfg's.  This decision has allowed Master Roll to significantly reduce the leadtimes on induction hardened jobs and also allows opportunity for Master Induction to provide this same service to outside customers in a timely fashion.  

Master Induction Heat Treat, LLC also provides rough turning, centerless grinding, bearing reconditioning, straightening, drawing, and quick annealing as required.
