Success stories<br />
A linear robot removes the lever and places it on a conveyor belt. After a defined cooling line, the employees fit a pin and a greased<br />
spring on the levers; they perform a visual check and place the parts in the grey trays.<br />
Stewo the opportunity of further optimising<br />
the workflow and structuring procedures<br />
in an optimum way. “Amongst<br />
other things, we now have fixed warehouse<br />
locations for each product. We<br />
have also introduced a new, c<strong>en</strong>tralised<br />
function for id<strong>en</strong>tifying scrap. This creates<br />
a more systematic approach to detecting<br />
and eliminating faults,” explains<br />
Michael Stelzer, continuing, “About t<strong>en</strong><br />
employees in each shift work in what we<br />
call the quality gate. Each is responsible<br />
for one product group, notifies the corresponding<br />
departm<strong>en</strong>t about faults<br />
that are detected, and th<strong>en</strong> works out<br />
pot<strong>en</strong>tial solutions together with those<br />
colleagues. In this way, we have be<strong>en</strong><br />
able to reduce the scrap proportion significantly<br />
once again. We now have a<br />
very closely meshed production system<br />
which guarantees total traceability.”<br />
Steering wheel lever set as a<br />
complete module<br />
About half of the <strong>en</strong>tire production in<br />
Romania is for the major order from<br />
Audi. Stewo produces a complete steering<br />
wheel lever set for the Ingolstadt au-<br />
tomobile manufacturer. The injectionmoulded<br />
turn indicator, windscre<strong>en</strong><br />
wiper and cruise control levers are padprinted<br />
on the spot, and assembled with<br />
outsourced parts to make the module.<br />
Stewo built all of the injection moulds<br />
and printing systems for this itself. A<br />
goods carrier transport system is used for<br />
semi-automatic assembly of the levers.<br />
A robot injects the lubricating grease into<br />
the steering wheel lever set. In addition<br />
to a visual inspection, the feel of the<br />
modules is now also evaluated. Furthermore,<br />
Stewo has introduced artificial<br />
