MIM Furnace Design and Use

CM Furnaces was one of the very first companies in the USA to make a completely automated pusher furnace for MIM that could handle all steps of MIM processing in a single production furnace. This includes almost any reducing atmosphere, as well as being adapted to handle the large amount of binders that are released by the parts. A continuousRead more ›

Powder Metallurgy Sintering Considerations

While the topic of the “hydrogen economy” has heated up in recent years, there is still no conclusive research showing that hydrogen production for fuel is cost effective in the long run. But in the world of industrial furnaces, hydrogen has been a heated topic for fifty years (pun intended…) Pure hydrogen gas (H2) is one of the most effectiveRead more ›

High Temperature Furnaces for Technical Ceramics

As anyone involved in the production of technical ceramics knows, the precise high-temperature firing of ceramic material in a furnace is integral to the overall quality of the process. Perhaps the most high-profile example of this would be firing of the heat shield tiles used on the space shuttle. These tiles are formed from pure silica fibers and heated toRead more ›

What is a Muffle Furnace?

While the term “Muffle Furnace” or “Retort Furnace” is still in use today, it doesn’t really mean the same thing as it did in the early 20th century when wood and coal were the primary ways to heat a furnace. A Muffle Furnace’s primary attribute is that it has separate combustion and heating chambers. The “Retort” is a gas sealedRead more ›

Selecting a Glass furnace for batch Production.

The conversion from raw materials to molten glass in the glass fusion process has become more complex and specialized as the range of materials and increasing desire for reproducible quality has progressed in the last decade. Indeed the proper instrumentation and control of glass melting furnaces can yield large savings in fuel and significant increases in throughput. CM Batch andRead more ›

CM Furnaces Helping Solve the Nuclear Fuel Disposal Problem

The U.S. Department of Energy is working to immobilize excess plutonium at its Savannah River Site (SRS) as part of a two track approach for the disposition of weapons usable plutonium. The Plutonium Immobilization process involves the disposition of excess plutonium by incorporation into ceramic pucks. The ceramic pucks, after pressing, are roughly 3-1/2 inches in diameter by 1-3/8 inchesRead more ›

Welcome to CM Furnaces

Congratulations, you’ve landed at the CM furnaces blog. We hope it will be the first of many visits as we attempt to present our thoughts on furnaces, kilns, heating, cooling, manufacturing, made in the USA, and any other hot topics that strike our fancy…. But first, a little about us.  Since 1946 CM Furnaces has been breathing fire into hundredsRead more ›
