The deep drawing process is a plastic forming technique that can be done either cold or hot. It involves forming metal sheets or other materials with a low cross-sectional ratio by placing the material between the two halves of the tool and applying a significant force through the press. The main purpose of deep drawing is to transform steel and aluminium sheets into spatial objects of various shapes and forms.
