When a newly-manufactured vehicle is ready to be powered up and driven, its first destination is a nearby checkpoint, where the vehicle is assessed for performance and quality on all fronts: Tire balance, engine/charging power, light/horn operation and more. If any part is found to be lacking in terms of functionality, the vehicle is sent to an adjacent area where repair workers troubleshoot the problem, sometimes using compressed air tools to fix issues. Once the vehicle has passed this stage of the inspection, it’s appraised for its market value and set with a price tag. From there, the vehicle is taken to a shipping lot, from which it will ultimately travel to a dealer’s lot, either domestically or abroad.
The various parts that make up a vehicle are produced at different locations. Therefore, the planning of each vehicle is a complicated process, since every single part has to be produced, tested, readied and delivered on the date when production is set to commence. In order to ensure that everything is ready when needed, car makers stipulate that component manufacturers must test and inspect all vehicle parts prior to shipment. This allows the assembly plants to ensure that all incoming parts bear the Statistical Process Control (SPC) seal of approval and are defect-free.
When components are first put together at an assembly plant, a Vehicle Identification Number (VIN) is given to each new car, truck or van on the production line. This allows the specialists in charge of overseeing the process to trace the development of each vehicle from “embryonic” to fully-built form. In doing so, quality control is executed on a step-by-step basis during the assembly of each vehicle, and imperfections are rectified before a body shell or chassis is sent to the next set of hands.
This marks a dramatic improvement from the days when inspections and corrections were only performed on finished vehicles, because money and time are saved in the process of assembly. Today’s assembly plant efficiency has all been made possible by automotive air compressors, which give tools the exact power needed to perform the required functions with utmost precision and speed.
