What is Deep Drawn Stamping?
Deep drawn stamping refers to the process of forming sheet metal under compressive and tensile conditions to into a cavity, producing a closed bottom, round, or irregularly shaped cup or cylinder. It should not be confused with stretch-forming. The material is actually forced into a plastic state as it is dragged over the die radius and down into the die. This compression process is done under calculated and very controlled conditions involving blank-holding pressures, punch and die radii, punch speed, and lubrication.
The end result creates a hollowed vessel, which can be cylindrical or square/rectangular in nature. Deep drawn products vary in size, from very shallow, requiring a single draw operation, to very deep, requiring many draw and re-draw operations. Deep drawn parts are very versatile and are used across a diversity of industries—from electronics to automotive and refrigeration, plumbing, and lighting. Items that have been deep drawn include assembly housings, industrial tanks, pressure vessels, and fire prevention devices. More “everyday” items that are deep drawn are appliance parts, containers, kitchen sinks, and fire extinguishers.
