About CM Furnaces
CM Furnaces Inc. was founded in 1946 by Seth Combs and James Murphy in Bloomfield, New Jersey. The company's original product line centered on refractory metal coils made from molybdenum and tungsten for the lighting and electronics industries. As demand grew, CM began building furnaces to support that production work, and high-temperature laboratory and industrial furnaces gradually became the company's core business — a focus it has maintained for nearly eight decades.
The flagship Rapid-Temp series covers a broad temperature range through several numbered lines — including the 1200, 1300, 1400, 1500, 1600, 1700, and 1800C series — offered in box and tube configurations with front-loading and bottom-loading options. The 1000K series tube furnaces operate continuously to 1200°C and are available in horizontal and vertical, single- and multi-zone layouts. Across all lines, CM Furnaces ovens and furnaces can be configured for air, inert, or reducing atmospheres, with sealed retort systems and hydrogen safety packages available. High-purity alumina fiber insulation, double-wall stainless steel construction, and molybdenum disilicide heating elements are standard features that set CM equipment apart from lower-cost alternatives.
CM Furnaces serves an exceptionally wide range of end markets. Ceramics and ceramic injection molding producers rely on CM ovens for debinding, sintering, and co-firing. The nuclear industry — including national laboratories — uses CM furnaces for sintering nuclear fuel pellets and ceramic waste forms. Additional sectors include powdered metals, refractory metals, glass manufacturing, fiber optics, crystal growing, fuel cells, additive manufacturing (metal 3D printing sintering and debinding), universities, and government research facilities.
Buyers seeking used CM Furnaces equipment on the secondary market are drawn by the brand's well-documented build quality and long operational lifespan. Because CM designs and manufactures everything in the USA with premium components, machines retain strong resale value and remain serviceable for decades. Replacement parts and technical support are available directly from the factory, reducing downtime risk on pre-owned units. For labs and production facilities that need proven high-temperature performance without the lead time or price of new equipment, a used CM Furnaces oven or furnace represents a practical, cost-effective choice.
