MIM Process Overview – MIM Furnace Criteria

In MIM design there are many variations of the initial forming process where MIM manufacturers add their particular process differentiators.  Whether your processes involves metals or ceramics, the key to reproducible production of precise metal parts requires a carefully planned and controlled sintering/debinding operation. Molding plastic parts is similar to molding metal parts in many ways such as designing draftRead more ›

Sintering Furnace Selection Considerations

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 andRead more ›

High-Temperature Sintering Furnaces 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 ourRead more ›

Bring Heat Treating Capability to your Machine Shop

If you are one of the thousands of machine shops or prototype houses throughout the country that is routinely outsourcing their heat treatment work to expensive labs with long lead times, we have a suggestion for you:  Consider bringing your heat treating capabilities in-house.   Some of the more common processes that machine shops outsource include: Hardening or Tempering ofRead more ›

Batch Furnaces For MIM Production

Batch furnaces for MIM are popular with companies or labs working with a number of different materials and part mixes that require process flexibility. Whereas a continuous furnace presents a fixed temperature along the line of travel, batch furnaces can offer programmable temperature profiles, programmable soak times, and lower overall operating costs. This can be important if you need to makeRead 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 continuousRead more ›
