Introduction: CM Furnaces is known for state of the art design and manufacturing of all types of air, hydrogen and inert atmosphere electric furnaces. Though many of our furnaces are of standard design and construction, CM has specialized in furnaces for a variety of applications and in updates of standard equipment to meet specific needs.
History: The company was founded in 1946 by Seth Combs and James Murphy. The main product line at the time was refractory metal coils (molybdenum and tungsten) used in the lighting and the electronics industry. CM began manufacturing furnaces in order to produce the coils and over time the manufacture of high temperature laboratory and production furnaces became CM's primary product. The fabrication of refractory metal coils remains a department within the company.
Technology: Realizing the need for high technology materials processing equipment, CM is actively engaged in the development of equipment to meet the ever changing requirements of research and production. All CM furnaces employ resistance heating elements matched to specific atmosphere, temperature and process requirements. All furnaces can be supplied with an electronically controlled elevating, rotating or traveling mechanism. Standard furnaces cover a general temperature range from 1000°C to 2200°C and the company specializes in furnaces at the high end of this range. Furnace atmospheres include air, hydrogen and inert atmospheres such as nitrogen, argon and helium.
