What is Ceramic/Glass Annealing?

Continuous Strand annealing furnace

Annealing occurs by the diffusion of atoms within a solid material, so that the material progresses towards its equilibrium state. Heat increases the rate of diffusion by providing the energy needed to break bonds. The movement of atoms has the effect of redistributing and eradicating the dislocations in metals and (to a lesser extent) in ceramics. This alteration to existing Read More

Sintering Furnace Selection Considerations

Production Sintering Furnace, Pusher Furnace

High-temperature sintering furnaces  are utilized in powder metallurgy for sintering stainless steel and, in some cases, iron-based materials. They are exclusively used in refractory-metal fabrication of molybdenum, tungsten and rhenium. High-temperature sintering furnaces are also utilized in the nuclear-fuel industry for sintering uranium oxide. The ceramic industry has always used high-temperature processes for sintering, co-firing and metallizing. To properly select and Read More

Production Furnace Throughput Defined

It is very common in several industries to discuss the output of a continuous furnace in terms of pounds/hour. This is an interesting number and easy to understand, however, it is misused most of the time. The origins of this output rating came from lower-temperature furnaces, specifically traditional mesh belts. If you were to speak with the belt manufacturers themselves, Read More

High-Temperature Sintering Furnaces for Production

Continuous Sintering Furnace for Production
For production sintering operations, certain furnace design considerations are common regardless of whether you are working in metals, ceramics, or glass and regardless of what industry you work in. In order to achieve compression without liquefication, accurate temperature control and careful atmosphere monitoring are essential to uniformity and throughput. Furnaces for normal sintering applications are often continuous-belt furnaces like our Read More

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 continuous Read More
