duce costs for the vehicle manufactur-
er. Another option is the installation of a
surface-treated torsion spring assem-
bled by the SCHERDEL assembly tech-
nology division as a complete compo-
nent with cushioning foam to minimize
noise and a clip. It can also be installed
after the paint process which also helps
to improve cost efficiency. Besides
SCHERDEL surface finishing and as-
sembly technology, the in-house tool
making and mechanical engineering ca-
pabilities are much sought after. For ex-
ample, special machines were devel-
oped for spring manufacturing which
ensure high pre-tension in the spring
and guarantee the force test result is
100%. All the tools required for spring
manufacturing were produced by
SCHERDEL. The said assembly tech-
nology division is also available for spe-
cial bespoke solutions, for example the
integration of gas dampers for cushion-
ing the limit stop in the boot. Thanks to
the Groupʼs production skills in the field
of tube bending, punching and welding,
a complete gooseneck hinge is avail-
able “Made by SCHERDEL”. The FEM
calculation once again enables the de-
sign of special tube cross-sections, re-
sulting in a reduction of the component
weight. It should also be mentioned
that, as an alternative to tailgate
springs, SCHERDEL also develops and
manufactures torsion bars, which, like-
wise, solve the problem of “comfort” in
a cost-effective manner.

Röslau plant –
a success story
SCHERDEL Druckfederntechnik
Röslau GmbH & Co. KG – one of
the largest compression spring
production plants in Europe –
recently celebrated its 10th an-
niversary at a new location in the
company of the German Federal
Minister of the Interior, Hans-Pe-
ter Friedrich. Under the watchful
eye of plant manager Klaus
Katholing, DFTR, as the compa-
ny is known for short, has experi-
enced unprecedented success
over the past decade. The shop
floor area has gradually in-
creased from the original 7,500
square metres to the current
12,000 square metres. At the
same time, the number of em-
ployees has risen by over 30%
since the start of production in
2001. Roughly 170 machines are
in operation “24/7” at the
SCHERDEL location in Röslau.
DFTR supplies the majority of
the products – primarily ABS
parts, transmission springs, com-
ponents for the engine manage-
ment system and springs for
brake systems – to automotive
customers and their main suppli-
ers. Up to 1,800 different types of
springs are manufactured at the
location in Röslau each year.
Around 350,000 packages of var-
ious shapes and sizes leave the
plant over the course of a year.
DFTR is a key internal supplier of
other plants in the SCHERDEL
Group
. For example, Röslau sup-
plies millions of parts to the
SCHERDEL location in Friedau,
where the DFTR parts are as-
sembled with other components
to produce a composite part or
even a complete system.
The extremely positive develop-
ment has resulted in DFTR be-
coming the leading compression
spring plant in the SCHERDEL
Group
. This means that technical
developments for new machines,
installations and production
processes are tested in Röslau
with the findings being passed to
other manufacturing locations for
compression springs. Colleagues
from these other locations also
receive professional training and
gain invaluable experience at
DFTR in Röslau.
