Automobile Assembly Process

The Parts
Individual parts of the car are constructed in various
plants around the country. The parts are shipped to the
construction plant via trains or trucks, and it is here that
the car is actually assembled.
Start With the Frame
Cars are constructed from the ground up. The car's frame
is secured to the assembly line, and from here, the car
will be pieced together.
Installing the Parts
The frame moves down the line, and installation of parts
begins. The suspension, gas tank, axles, drive shafts,
wheel drums, steering boxes, gear boxes and breaking
systems are all installed at this phase.
Engine and Transmission Installed
The engine and transmission are paired together and
hoisted into place in the car. This is usually done by
robots, as the parts can be extremely heavy. The parts
are bolted into place by workers.
Building the Shell
The shell of the car is built next. The floor pan is laid
down, and the quarter panels are attached. The front and
rear door pillars are attached. Robots are also generally
used in this phase.
Final Body Components
The final body components are installed, including, doors,
hood, fenders, trunk lid and bumpers.
Inspection and Washing
The body of the car is brought into an inspection area,
where it is checked for any dents or damages. Once it is
approved, the entire body is washed thoroughly to
remove residual oils.
Paint
Calibrated robots apply the paint job, and the car is then
put into a baking area where the paint dries into the
typical sheen.
The Inner Workings
Workers take the car's shell and install all of the electrical
wiring, lights, seats, door trim, brake pedals, gas pedals,
carpeting and all the glass, except for the windshield.
The Shell and the Frame
Robots suction cup onto the windshield and put it in place
on the car. The shell of the car is then mounted on top of
the car frame. Once properly connected, the car receives
its battery, tires, anti-freeze and gasoline.
Test the Car
The vehicle is started and driven to a test area to make
sure it meets the proper quality standards of the
manufacturer.
