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.
