3. Technology
FAST stands for Field Assisted Sintering Technique.
This refers to the heating of a mold by means of current flow. The unit is not heated from outside as usual
in a furnace (indirect), but from inside (direct).
Dr. Fritsch applies a self-developed direct current process (FAST-Direct-Hot-Pressing). This process can also
be used with electrical non-conductors such as various
ceramics.
In this case heating occurs through the sintering mold
and therefore much closer to the sinter part than with
conventional heating technologies.
This heating technology has significant advantages:
● The very short sintering cycles reduce the unit costs
at a higher productivity
● The significant reduction of the grain growth
improves the property of the material
● The attainable densities are considerably higher
than with conventional sintering methods
● The temperature control is very precise due to the
direct resistance heating
● The development time for new materials can be
substantially shortened
● New material combinations can be manufactured,
for example FGMs (Functionally Graded Materials),
which cannot, or only with great difficulty be processed with conventional methods
● Parts can be produced at near net shape
● Expensive production steps can be skipped; for
example the application of adhesive and solder
between the backing plate and the friction material
and also the final calibration. Even the copper
plating of the carrier might be omitted.

4. Applications
Dr. Fritsch has more than 60 years of experience in the production of FAST-DirectHot-Presses for industrial applications.
The machines are designed for a daily
3-shift operation, all reasonable work processes are automated and easy to operate.
The equipment is arranged in a compact
housing. The risk of operating errors is re­
duced due to the intelligent programming
and not freely accessible components.
