For manufacturers of friction linings

Benefit from the technical superiority of FAST/SPS-sintering by Dr. Fritsch.

• Performance
  In dynamometer tests, friction linings sintered with FAST/SPS show much better friction coefficients and more homogeneous wear behaviour compared to traditionally sintered materials. Additionally, shear strength performance is improved due to a better connection between friction lining and carrier. This is a direct result of the reduced grain growth by applying a very short sinter cycle.
• Productivity
  Thanks to the direct current heating of the friction pads, cycles of 15-90 minutes can be achieved. Short cycle times result in a higher productivity and make your production more flexible
• Density / Porosity of parts
  The combination of pressure and temperature also allows it to adjust the required density very precisely. Theoretically, much higher densities than on conventional sintering technologies can be achieved
• Joining of friction material and back plate
  Due to the combination of pressure and temperature, the friction material can be sintered to the back plate without the use of soldering material. As a result, the costly solder is saved and one production step can be skipped.

Dr. Fritsch FAST/SPS-presses are operated by almost all world leading manufacturers of friction materials. When driving your motorbike or travelling on high-speed train, there is a high chance that the brake pads have been produced on a Dr. Fritsch FAST/SPS-sinter press.

For manufacturers of (hard) metal parts

Benefit from the technical superiority of FAST/SPS-sintering

• Process optimization due to shorter cycle times.
• Short sinter cycles reduce grain grwoth thus produce higher densities and better microstructure of the sinter material
• Improvement of hard-metal quality by avoiding potential Co losses at high temperatures and with long sintering times.
• Processing of binder-free hard-metal and/or hard metal with a low binder share (≤3%) without problems, due to the combination of pressure and temperature.
• Combination of high pressure with very high temperatures of up to 2.400°C; it is thus possible to sinter pure tungsten, for example.
• Use of alternative binder systems or binderless sintering.

Generating electricity out of waste-heat

Thermoelectric Materials generate energy out of the temperature difference between a heat source and the colder surrounding. An example are automobiles where the temperature difference between hot parts, for example the exhaust pipe, and the colder atmosphere outside the car can be used for generating electricity. The thermoelectric materials are mounted around the exhaust pipe and the generated electricity charges a battery which powders the car when driving in the city. Other applications are existant in the field of aeronautics and space technology, the utilization of industrial waste heat and in private households.

FAST/SPS sintering is an essential part of the production of thermoelectric materials. Grain growth needs to be reduced to a minimum in order to ensure the best thermal and electrical conductivity. Therefore a quick sintering process is a must have. The Dr. Fritsch machine portfolio covers all powder metallurgical needs in connection with the production of thermoelectric materials:

• Mixing (PM 10, PM 20)
• Dosing (DWA 11)
• Cold Pressing (CPG 100)
• FAST/SPS-Sintering (z.B. DSP-507, DSP-515 oder DSP-520)
• Automation (MFZ 554, FM512, SMV218 or a customized solution)

Dr. Fritsch is the only manufacturer of FAST/SPS sinter presses to cover all other relevant production technologies in powder matallurgy. Dr. Fritsch FAST/SPS-sinter presses are successfully operated by several producers of thermoelectric materials.

For Research and Development

FAST/SPS-sintering by Dr. Fritsch is particularly suitable for research and development. Universities, R&D-departments and research institutes around the world rely on machines made by Dr. Fritsch.

• The FAST/SPS sinter presses are extremely flexible and can process materials of every kind.
• This method is consequently excellently suitable for tests and experiments.
• Short cycle times guarantee quick results and a high number of tests per day.
• The short sinter cycles reduce grain growth, thus allow the development of totally new and improved materials (e.g. thermoelectric materials and FGMs). 
• Thanks to the control unit, processes can be displayed and reproduced very exactly.
