Industrial Furnace Processes and Applications

Metal Injection Molding

High temperature atmosphere applications can now be processed both efficiently and economically with minimal technical expertise. CM Furnaces has developed a line of “hot wall” batch furnaces known as the 1500/1700 Series with complete process control for temperature and atmosphere without the added expense of “cold wall” vacuum construction. Offered in two temperature ranges and several sizes, these furnaces are used for MIM debind and sintering as well as virtually any application requirement where vacuum is not absolutely necessary.

Technical Ceramics

Ceramic furnaces came right after high temperature refractory metal furnaces. In some cases the atmospheres were the same. In many cases the atmosphere was in air. This branched to atmospheres of nitrogen, inert and at times pure oxygen. There were many aspects of ceramics that the furnace cover including sintering, co-firing, metallizing, annealing, flattening, and powder processing. These, like many of CM’s furnaces are in both standard and custom configurations.

Glass

CM has been involved in high temperature and specialty glass for decades. We offer different designs based on the specific temperature, atmosphere and application. Both standard and custom configurations are provided.

Annealing

The CM 200 Series continuous annealing furnaces are designed for years of trouble-free service in the processing of wire, rod, strand, strip and tube products. These furnaces are ideally suited for copper, copper alloy, nickel, nickel chrome, titanium, stainless steel and refractory metals. The 200 Series features heavy-duty construction, an energy saving combination of fiber and brick insulation, precise temperature control and requires minimal maintenance.

Debinding

The 100 Series is specifically designed for catalytic debinding of BASF polyacetal binder from injection molding of metal and ceramic powders. These are batch debinders offered in four sizes from lab-scale to production level processing. All stainless steel construction with complete control of atmosphere and temperature profiles is standard.Batch catalytic debinding ovens for BASF polyacetal binder system are offered in various sizes for research, development and production. For process development and small production runs CM Furnaces offers batch atmosphere furnaces capable of both debinding and sintering. These units are offered with maximum operating temperatures of 1450°C (2642°F) and 1700°C (3100°F) with either reducing or inert/reducing atmospheres.

Sintering

CM has been involved in sintering throughout its history. We have produced furnaces, both batch and continuous for many different materials in various atmospheres and temperature ranges. For process development and small production runs CM Furnaces offers batch atmosphere furnaces capable of both debinding and sintering.Our furnaces have low operating costs. They have a very robust design with very little ongoing maintenance costs.

Calcining

For calcining applications, the CM 1600 Series Rapid Temp Lab Furnaces are the most reliable and widely used. They offer rapid heating and cooling rates, uniform temperature control, compactness, and sturdy construction for long term use.

Brazing

The CM 300 Series and 400 Series continuous furnaces are available in a variety of configurations from manually loaded lab-scale units to fully automated production systems. Depending on application requirements such as brazing, other features are added such as preheat sections, wax or binder removal sections, multiple zone controls, low or high dewpoint features, and turn-key automated pusher.

Metallizing

Early in our history, CM was involved in the metallization of ceramics for power and electronic applications. These metallizing furnaces were made in different sizes and are for specific process requirements and output. It is something that CM is still very involved with today. From metallizing we moved early into co-firing of multilayer ceramic packages. The CM 300 and 400 series are available from lab-scale size to fully automated production systems. Typical configurations include preheat sections, cooling sections and various optional features offered for metallizing and several other applications.

Thermal Cycling

Our CM 1600 and 1700 Series furnaces incorporate a graded insulation package using high purity alumina fiber. Due to the low thermal conductivity and light weight of this insulation extraordinary fast thermal cycling is possible. These furnaces will not hot spot at high temperatures and are resistant to degradation. The double wall shell construction allows the fan cooling feature to maintain reduced skin temperatures while keeping the element terminals cool, extending element life.

Atmospheric Controls

The CM 1600 Series offers standard atmosphere options with the tube furnaces and a gas-sealed option on our box furnaces for inert atmosphere operation. In addition, the most reliable and widely used lab furnaces available, the CM 1700 Series Rapid Temp Lab Furnace offers rapid heating and cooling rates, uniform temperature control, compactness, and sturdy construction for long term use.These furnaces will not hot spot at high temperatures and are resistant to degradation. The double wall shell construction allows the fan cooling feature to maintain reduced skin temperatures while keeping the element terminals cool, extending element life and providing superior atmospheric controls.
