INDUSTRIAL FINISHING: AEROSPACE COATINGS

CASE STUDY:

FLEXIBLE LACQUERING

WITH ROBOTICS

By Alexander Hunger

new multi-purpose Venjakob lac-
quering system was put into opera-
Ation for a service provider special-
izing in aerospace industry coatings.
The system is suitable for coating screw
threads as well as flat and rotationally sym-
metrical parts.
Aero-Coating GmbH in Wismar – an af-
filiate of Eifeler-Holding GmbH & Co. KG
based in Düsseldorf/Germany – coats com-
ponents made of metal or polymer materi-
als with functional layers against contact
corrosion for businesses mainly in the
aerospace sector.

Flexibility as an
Essential Requirement
For years, the components were mounted
on special carriers and manually coated. The carrier system is suitable for components of various sizes and shapes.
However, this limited the throughput The system offers high performance due to the parallel use of two linear axes.
capacity and the finish quality was
not reproducible.
For this reason, the decision was made to
invest in a coating system. A very specific re-
quirements profile was created which pre-
supposed a “dual” and particularly flexible
application since Aero-Coating coats screw
threads in high volume, but also flat 3D and
rotationally symmetric parts.

Lacquer Booth with
Two Loading Possibilities
The company also desired a compact total
system as an island solution with a structured
design of the individual assemblies – han-
dling and transport, application robotics,
spraying system and booth housing with ex-
haust and supply air components. The con-
trol and formula management was supposed
to be mostly automated and operation of the A rotary table allows the coating of flat and rotationally symmetrical parts.
robot based on simple programming via copy- The robot needs approximately one minute for the coating of the workpieces.
