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.

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. 

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. 

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guns have been replaced by a sophisticated 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. 

When all components are completed, the engine, 

axles and transmissions are assembled and 

tested together.

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. 

At this stage, final exterior and interior inspection 

are performed, cars are fully tested and repairs 

are made as necessary.
