Proper construction of a vehicle often requires careful
inspection at every step of the production process, with
each step demanding very specific lighting conditions.
The first essential for an automotive production center is good
general lighting, which is important for creating a pleasant working
environment with good conditions of visibility and comfort.
There are six main phases in the production of a
vehicle: stamping, body-in-white ( B I W ) assembly,
paintwork, engine assembly, final assembly and car
testing and delivery.
Stamping
This is the process by which parts (bodies, doors,
bonnets, floor pans) are cut out of sheet metal.
Completely automated-machines known as
transfer presses perform all the work of cutting
and shaping the metal.
Body-in-white assembly
This is the assembly-line operation during which all
the various parts are put together and then welded
to make the “shell” either by semi- or fully-
automated machinery.
Paintwork
Here too, the lines are automated to reduce waste
and pollution. The body shell is cleaned, dipped in
an anti-corrosion bath and dried thoroughly.
This process is known as cataphoresis. Paint spray
guns have been replaced by a sophisticated
procedure based on the principle of aerostatics
(the mechanics of elastic fluids), thanks to which
paint particles are spread in a perfectly even layer.
Water-based paint is used to reduce the release
of solvents into the air.
Engine, axle and transmission assembly
When all components are completed, the engine,
axles and transmissions are assembled and
tested together.
Final assembly
During final assembly, all the remaining parts of
the car are put together: seats, wheels, engine,
dashboard and so on. Parts are delivered directly
to the assembly lines by other production sites
(or power train plants) and by suppliers on a
just-in-time basis.
Car testing and delivery
At this stage, final exterior and interior inspection
are performed, cars are fully tested and repairs
are made as necessary.
