Mowry Enterprises, Incorporated supplies new, used and rebuilt heat-treating equipment, pairing furnace procurement with engineering and turnkey installation. The Massachusetts company is particularly distinctive for re-manufacturing existing furnaces with updated hot zones, controls, plumbing and pumps, and for developing complete heat-processing systems around a customer’s process. Its work spans process development, equipment specification and metallurgical analysis rather than stopping at the furnace sale.
