Hot Press Systems
Thermal Technology's hot presses are designed for high temperature, high pressure consolidation of powder materials. Operating at temperatures to 2250° C and uniaxial loads to 10 or 25 tons, this equipment is capable of densifying virtually all known ceramic materials. The vacuum furnaces are available with graphite, tungsten mesh, molybdenum mesh, or silicon carbide hot zones to meet specific process requirements. Atmospheres ranging from high vacuum to inert to reducing to oxidizing can be accommodated.
The basic models of hot pressing systems include the vacuum furnace, press load frame with rams, manual power supply with water-cooled flexible power leads, and manually controlled hydraulic force system.
With the versatility built into Thermal Technology's hot presses, high purity, and high strength technical ceramics can be fabricated. A variety of accessories can be installed at time of purchase or in the field at a later date.
- Robust four-column, rigid load frame
- Highly accurate force control
- Reliable powder densification and diffusion bonding
- Optimum hot zone temperature uniformity
- Low entry costs
- High level of repeatability
- Long life, low maintenance
Spark Plasma and Direct Current Sintering (SPS/DCS)
Thermal Technology's innovative rapid powder consolidation technologies, Spark Plasma Sintering (SPS) and Direct Current Sintering (DCS) utilize high amperage DC current for quick and even thermal processing. SPS (pulsed DC current) and DCS (constant DC current) systems quickly process conductive, non-conductive and composite materials, including nanomaterial, to any level of density with high homogeneity at lower operating costs. Thermal Technology's modular power supplies can be configured to your specific applications.
Unique to SPS is the DC current generating heat internally, as opposed to conventional methods of materials densification such as hot pressing, wherein the heat is external to the sample. While other traditional methods of materials processing require hours to reach peak temperature, Thermal Technology's SPS takes only minutes. The clear benefits of SPS are the significant savings of time and energy and the ability to retain nano-structures.
Emerging markets for SPS and DCS systems include the development of thermoelectric generators for automotive applications. This developing green technology converts waste heat from engine exhaust and industrial plants into electricity. Other applications include fuel cell materials, high strength and wear resistant tooling, sputter targets, diamond compaction for abrasives and the development of pure or mixed metallics, ceramics or cermets where maintaining nanometric and fine microstructure is required.
