Due to the current development of plastics in the field of polyurethane, it is possible to obtain a plate hardness of 40-95 SHA, which allows for deep drawing of containers of various purposes. An additional argument is the price of the material, which is several times lower in relation to rubber or fibroflex products. This allows the flexible punch forming method to be used for special or prototype applications, where the costs and time of tool production are the main argument. The paper presents one geometric model of a container, but formed from different materials, i.e. steel with a high content of chromium, aluminum alloy, copper, in order to compare the differences in their intended use, as well as the production method.
