Multifunctional system
for perfect application
Protecto systems make precise and homogeneous coating very easy and intuitive to realize. The picture shows the following application proce-
dures under UV light: laying a barrier by dispensing and then jetting with multi-line (left), jetting of large areas without distributor air (middle) and
jetting without distributor air with frame tool for high edge accuracy (right).

The application determines the equipment
Variety of coating applicators
We have the right equipment for every individual process.
Our broad portfolio of paint applicators allows a variety of
applications. Both proprietary developments come into play
as well as applicators from suppliers who have already es-
tablished themselves in the market. Various options such as
material needles, patented two-material nozzles and material
warmers, are available for the respective applicator. Thus,
the plant equipment can be selected using a wide range of
different accessories that provides the best combination of
cost-effectiveness and process performance.
All technical data is dependent on the application material and does not claim universal applicability. Specic parameters shall only be regarded as binding on
the basis of a material test.

Greatest possible process reliability
with innovative options
When it comes to coating, one thing is essential: precision.
Protecto systems are designed to ensure that the required
volume of coating is always evenly applied, whether
through a pressure valve, a cartridge or a pump from the
original container. Automatic needle measurement checks
the target position of the applicators in freely denable
cycles and if necessary corrects the coating program au-
tomatically. The dispensing of the lacquer is controlled by
the software, which loads the appropriate coating program
with the suitable lacquer and nozzle type. An optional heat-
ed nozzle keeps the protective coating always at a constant
temperature and thus a consistent viscosity regardless of
environmental conditions. A specially developed lacquer
lance with a level indicator prevents bubble formation when
changing the lacquer.
For absolute process reliability Protecto systems are
optionally equipped with a ducial camera. This means the
coating program can be corrected and coated in the correct
positionby registering the marks even if a board is laid into
the flight bar inaccurately. A barcode checks whether the
set coating program is right for the assembly in place. If
there is a deviation the process is automatically blocked.
A high-precision weighing cell is optionally available for the
Protecto systems, which compares the weight of the paint
applied by any given applicator with a previously dened
setpoint value and provides the user with corresponding
feedback in the setup mode as well as cyclically during
series production. As a result, errors in the fluid circuit can
be easily and efciently detected, and eliminated without
delay. The acquisition of weight data, as well as congu-
ration and adjustment, are software controlled and can be
individually adapted.
