Industrial furnaces are built of several kinds of high temperature (refractory) materials to hold the process material and hold in the heat without breaking down during the several months that they usually run. 

Induction heaters use an electrical source to drive alternating current (AC) through a coil to heat metal objects

Ceramic tube and ceramic rod products are suitable for use in applications requiring high temperature strength, erosion resistance, electrical or thermal insulation, and other specialized characteristics.

Heat treating services perform thermal treatments to modify the properties of metals and metal alloys. Common processes include annealing, austempering, case hardening, conventional hardening, homogenizing, hot isostatic pressing (HIP), martempering, normalizing, precipitation hardening, shot peening, solution treating, spheroidizing, stabilizing, and stress relieving.

Crucibles are vessels used to melt and process materials at high temperatures.

Refractory shapes include recasted, preformed or sintered refractory products that are formed prior to installation in furnaces, boilers or other high temperature equipment. 

Power transformers convert power-level voltages from one level or phase configuration to another.  They can include features for electrical isolation, power distribution, and control and instrumentation applications.

Vacuum furnaces are heat-treating furnaces that use a low atmospheric pressure instead of a protective gas atmosphere. This helps to alleviate surface reactions

Laboratory furnaces provide continuous heating to process samples and materials

Heating furnaces convert gas, oil, electricity or other fuels into heat for distribution within a structure. They are the central heating devices within HVAC systems

Industrial design services develop and enhance the appearance, usability, and value of many types of products. Considerations include product styling and architecture, as well as ergonomic and safety considerations

AC motors include single, multiphase, universal, induction, synchronous, and gear motors. They also include servomotors.  

Furnace controllers are used to control temperature, heat delivery, and other variables in industrial furnaces. They control the burner flame, air mixture and trim to maintain and optimize furnace performance

Engineering design firms provide total design for new components, products and equipment, including load analysis, part and material specification, manufacturing drawings, product manuals, and often manufacturing support and/or certification documentation

Linear motors generate force only in the direction of travel. They are capable of extremely high speeds, quick acceleration, and accurate positioning.
