In his book b.m. Kupplungsbau , Kai Rheineck offers a photographic ode to craftsmanship. As the industry transitions to e-mobility, many suppliers are facing the consequences of this shift. With a blend of nostalgia, curiosity, and admiration, Rheineck has documented the factory floors of a company where a vanishing world of work has been preserved as if in a time capsule. The photographer has lovingly portrayed workbenches, machines, and spare parts. The haze of machine oil, abrasives, and metal shavings creates an intensity and atmosphere that draws the viewer right into the image.
