Deep drawing involves creating threedimensional shapes , such as cylinders or domes , from a flat sheet of metal . In deep drawing , sheet metal parts are drawn into the desired shape using a die . A mechanical punch or press pushes the flat sheet metal through a die into its die cavity , forming a completely different drawn shape . The resulting sheet metal part has no parting lines , seams or cuts .
In the deep drawing process , the original sheet metal thickness remains the same . The forming process only draws the sheet through a die without stretching it .
“ The components can be created in one piece , reducing the need for additional assembly . This has the added benefit of seamless construction , which is suitable for waterproof or airtight applications ,” commented manufacturer , Hudson Technologies .
“ Deep drawn stamping is highly versatile and can be used to create complex , detailed components with accuracy and repeatability . Deep drawn parts are exceptionally strong due to the extreme amount of compression exerted on the metal during the forming process . The fundamental structure of deep drawn metals is often highly compressed into a very hard crystalline structure ,” it added .
Deep drawing can produce precise and intricate parts , including both symmetrical and asymmetrical parts . It is one of the most widely used processes in sheet metal forming . Many different metals ( such as cold rolled steel ; stainless steel ; titanium ; copper ; brass ; aluminium ; HSLA and others ) are included in the deep drawn metal stamping process .
Examples of commonly manufactured deep drawn parts include automotive body parts ; faucets / taps ; compressed gas cylinders ; bathtubs ; sinks ; cans ; jet engine components and cooking pots .
