PRE-TREATMENT, SURFACE PREPARATION, DEGREASING & CLEANING
Linked Cleaning and mass fi nishing
solution for brake components
Continuous processing of parts
that must be glued together
LUMAG, a well-known Polish
brake pad manufacturer,
presented Rösler with the
challenge of fi nishing a
surface in order to maximize
its adhesion characteristics
for a subsequent bonding
stage. Rösler offered a
solution for de-oiling and
surface fi nishing of brake
pad carrier plates directly
linked to a punch press.
LUMAG Sp. z o.o., founded by Mr. Marek
Zak in 1988, is specialized in the production
of brake pads for drum and disk brakes for
commercial vehicles. For the latter the
company, located in Budzyn, Poland,
developed its own manufacturing technology
resulting in significant quality improvements.
In addition, LUMAG develops, produces and
sells brake pads for passenger cars and
motorbikes under the trade name Breck.
De-oiling, deburring and
surface roughening
As a result of changing the production
method for the brake pad carrier plates, from
casting to stamping, LUMAG decided to
install a new in-house manufacturing line for
these products. This included a solution for
de-oiling, deburring and surface roughening
of the stamped carrier plates with lengths of
210-250 mm and widths between 90-110
mm. It should be noted that the components
have a slit or drilled hole for placing a
sensor, which monitors the wear of the brake
pad. These steps were intended to ensure
that the delicate stampings provide optimum
adhesion characteristics for the following
bonding of the brake pads. Another
requirement presented by the customer was
to directly link the finishing equipment with
the punch press, maintain extremely gentle
processing and complete automation of the
cleaning (de-oiling) and mass finishing
stages in continuous feed operation.
LUMAG decided to partner with Rösler for
The fully automatic de-oiling/washing and mass
fi nishing system is directly linked to the punch press and
allows for continuous feed operation. The only manual
operation is the replacement of the full transport bins
every few hours.
