Deep drawing

Deep drawing of ferrous and non-ferrous alloys is one of the most challenging forming processes, because of the complexity of controlling the flow of the sheet metal between binder, die and punch. In most cases, even an optimized tool design cannot guarantee a product free of splits, fractures and wrinkles. Ionbond PVD and PACVD coatings, with their low coefficient of friction and high wear resistance, can significantly improve the flow characteristics of the sheet metal. That limits draw ratios, protects tool surfaces and increases product yield.
