How A Car Is Made

We rely on our vehicles to get us where we need to go. But how often do we think about the process that is involved in making one of these machines? One car is an assemblage of thousands of different automobile parts from all over the world. By the time these parts reach the car manufacturing plant to be assembled, you car is finally in the last stage of its manufacturing process.
Once all the various parts arrive at the manufacturing plant, they can be assembled on an assembly line. It all begins with the chassis. The chassis is the framework of your car that supports its most essential components like the engine, transmission, driveshaft, differential, and suspension. Much of the work of the installation of these essential components is done by industrial robot arms that can assist workers in assembling heavy parts.
Once the chassis is assembled, the next step is the body. The body is usually built separately from the chassis. First comes the floor pan, which is the largest body component. A variety of panels and braces will be welded and bolted to the floor pan. Next the left and right quarter panels are robotically attached to the vehicle, and then the front and rear, roof, and body side panels are attached. After the body has been assembled and carefully inspected, the next step is painting. First, the car is immersed and cleaned of all dirt, oil, and residue. Then it is dried and dipped in a bath of undercoat paint that covers the entire body of the shell with primer. Next, it is dried and painted with a base coat of the chosen color of paint by specialized robots and then sprayed with a clear topcoat. The car is then transferred to an oven where the paint is cured at about 275 degrees.
Once the vehicle has been painted, workers assemble the interior of the vehicle, including seats, trim, wiring, dash, lights, etc. A robot installs the windshield. The shell is then tested for water-proofing. It is finally at this point, the body is then mated to the chassis and the car receives its final components like tires, battery, gasoline, etc. The car is now finished and sent for final inspection where everything is carefully audited for any defects. Once it passes inspection, it is transferred to a car shipping company. These companies specialize in shipping vehicles across the country and will ensure that the vehicle arrives at its destination in pristine condition. Through this careful process, the car finally arrives at a dealership to be sold to its new owner.
