Yes gary, This type of pressing requires rows of very large presses, when you consider the number of pressings required to produce a motor vehicle and the immense cost of tooling, its only by efficiently high production techniques that the cost per vehicle is kept relatively low. All pressings are now produced to very close tolerances, only possible by modern manufacturing methods, so when a vehicle reaches the end of the production line, it will not only start at the touch of the key, but tick over at the correct rate, from where it is driven to its designated area for transport.
These component parts, be they pressings or otherwise, are not stored ready for use, the old way, they are ordered to arrive on the production line at the precise time and place where they are to be fitted, and considering that the varieties of versions of the same vehicle, the ordering and production of parts
is of extreme urgency. Goffy
