deep drawing

Deep drawing is a metalworking process used to form sheet metal into cup-shaped, box-shaped, or cone-shaped articles. This is achieved by forcing the sheet metal into a die, often using a punch press or drop hammer.1

In metallurgy, drawing is a process that involves pulling metal through a die. While wire drawing reduces the diameter of a metal rod, deep drawing begins with a metal disk and forms it into a cup by pushing the metal through a die. This technique is commonly used in the manufacturing of items like aluminum beverage cans and brass rifle cartridges. Deep drawing is a type of sheet-metal forming, which is one of the five broad groups of metalworking processes.2
