s an acknowledged partner of
industry, the SCHERDEL
Group
constantly endeavours to create innov-
ative products which will provide the
customer with the greatest possible
benefit. Here, the introduction of new
materials and production processes
plays an important part in ensuring that
we live up to our principle of "Growth
thanks to innovation". That's why the
Group employs a large number of staff
and invests a lot of money in relation to
research and development work. The
aim is to keep extending the store of
knowledge pertaining to metal-working
which has been built up at SCHERDEL
over a period of more than 120 years.
Following the example of the company-
founders' pioneering spirit, the intention
is that, in the future too, the Group will
be a market-leader in relation to prod-
uct development. In order to provide all
the customers with an optimum service
in the field of research and develop-
ment, SCHERDEL has continuously in-
vested in modern testing facilities and
laboratory equipment. We would now
like to tell you about some of the most
important laboratory appliances and ex-
plain how they work.
The scanning electron micro-
scope
The sample placed in the test cham-
ber is scanned in a vacuum by means
of an electron beam. The resulting rep-
resentation of the surface topography
on the screen has a 3-D effect. This
high-tech instrument is used for exam-
ining defects during fracture analysis. In
addition, the production processes used
can be checked, for example, by exam-
ining the edges of stamped parts, burrs,
shot-peened or coated surfaces and
coating structures. Furthermore, it is
possible to detect corrosion and impuri-
ties. By means of the EDX analysis
system, a qualitative analysis of the
sample composition or of particular de-
tails, such as non-metallic inclusions,
can be carried out. Excitation by means
of an X-ray beam causes the electrons
of the individual atoms to move to an-
other electron shell or, as the case may
be, to jump back again. The energy
(voltage in electron-volts) required for
this is registered by means of a detec-
tor. The energy value indicates which
element is present. In the analytical
spectrum, in the case of particular volt-
ages, peaks thus become visible, which
can be assigned to the elements.
The X-ray diffractometer
This piece of equipment is used dur-
ing testing work in order to optimize the
production of components subjected to
dynamic stress – at SCHERDEL mainly
springs. It makes it possible to adjust
residual stress values as desired. When
valve springs undergo shot peening, for
example, the aim is to achieve a high
maximum value of residual compres-
sive stresses with a large penetration
depth of the residual compressive
stresses on the inside of the spring
coils.

Robert Sroka, factory manager of
SCHERDEL Schweiß- und Um-
formtechnik (welding and forming
technology) in Treuen
On 01. April 2010 Mr Robert Sro-
ka was appointed to the post of
factory manager at SCHERDEL
Schweiß- und Umformtechnik
GmbH (SSU) in Treuen.
Mr Sroka studied process tech-
nology at the Technical College in
Nuremberg, after which he worked
for three years as a planning engi-
neer in the field of exhaust-air de-
contamination. He then went to
the Technical College again, this
time in Schweinfurt, where he
studied industrial engineering. In
the following years he worked in
the controlling department and in
the management of two compa-
nies before finally embarking on
his career with SCHERDEL in
2003.
During the first year, as an assis-
tant to the Group Managing Direc-
tor, Walter Bach, he acquired an
extensive knowledge of the orga-
nization and procedures within the
SCHERDEL
Group
. He then
worked for Mr Wegmann in the
sphere of central production plan-
ning where he observed the in-
vestment activities of the whole
Group. He was in charge of vari-
ous process-optimization activities
such as optimization of set-up
times, order & cleanliness, or the
Kaizen system. At the same time
he was actively involved at various
locations, such as SCHERDEL
Marienberg, SSU Treuen or TPS
Bor, when problems arose.
Since 01. April 2010 Mr Sroka
has been factory manager of SSU
Treuen. His main aim is to ensure
that the location's capacity is used
to the full with a corresponding
production output and that, thanks
to good future prospects and an
independent profile, the company
will achieve economic success.
Mr Sroka is married and has two
sons. He likes to devote his
leisure activities to sport and also
enjoys spending time with his fam-
ily.
