How Are Cars Made?

The car production process begins with stamping and welding, before ending at transportation and sales. The process of making cars is quite a production, and automobiles go through many stages before emerging in their final, finished form, ready for use on the road.

Like building a house, laying the foundation for cars requires a bit of planning. Once the idea for a new car gets approval, assembly begins. Stamping is the first part of the car production process, followed by welding, painting, assembly and inspections. Some steps, such as the construction of engines and other mechanical parts, may be involved in the car creation process too, depending on whether the automaker makes and uses its own engines or uses those premade by other companies. During the phase of stamping, automakers flatten and heat long sheets of steel and cut them into various identifiable car parts, such as doors, roofs and hoods. Once the pieces are cut out into the proper shapes, they make their way to the welding stage, which involves putting them all together using high heat. Then, cars go to the painting phase, which involves a makeover complete with priming, surfacing, adding a top coat, and finishing with a clear coat for shine and polish. Lastly, cars receive their interior cabins in the assembly stage and move to inspections for quality control.
