From 1954 to 1994, Ford improved its engine casting process in many ways, as we can see from these two Ford-produced videos showcasing the cast-iron engine manufacturing at the Cleveland and Windsor plants, respectively. Computerization! Ergonomic work stations! Conference rooms? A gym?
But once you get past the preambles and the shiny new office furniture in the latter video, you start to see just how unchanged the process remained at its core (get it?). Molten metal still flows into molds; massive machines still bore, hone, grind, and polish raw castings; precision instruments adapted for mass production still ensure tolerances and consistency; line workers still put in long and arduous days.
