Stamping (metalworking)

Marx Schwab in Germany developed a new process for stamping that involved as many as 12 men turning a large wheel to press metal into coins.

Press and interconnected automation devices increase production rates, reduce labor costs and provide more safety for workers.

Progressive stamping is a combination of the above methods done with a set of dies in a row through which a strip of the material passes one step at a time.

The Tribology process generates friction which requires the use of a lubricant to protect the tool and die surface from scratching or galling.

The lubricant also protects the sheet metal and finished part from the same surface abrasion as well as facilitate elastic material flow preventing rips, tears and wrinkles.

They include plant and mineral oil-based, animal fat or lard-based, graphite-based, soap and acrylic-based dry films.

The term "Water-Based" lubricant refers to the larger category that also includes more traditional oil and fat-based compounds.

However, key issues such as quality control, high-volume application, and the need for material research into mechanical properties must be addressed before full-scale implementation of the technology is realized.
