Stamping Aluminum Sheet Metal

Ironing is the basic process used to make beverage cans see figure 2.

Stamping aluminum sheet metal.

Stamping also known as pressing is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Although most stamping operations use sheet steel special dies can cut and form steel bars up to 3 in. Metal stamping is a cold forming process that makes use of dies and stamping presses to transform sheet metal into different shapes. 3003 aluminum a general purpose alloy commonly used in sheet metal applications.

While it would be possible to include this offset in my 3d models i decided to incorporate it later on in the process. Happybuy semi automatic sheet embosser 2 to 4 characters per second metal embosser working plate 7 8inch x 5 3inch embossing label maker machine with 4mm aluminum 3 1 out of 5 stars 20 187 96 187. Aluminum stamping can also be anodized to enhance surface hardness and corrosion resistance in challenging. The method comprises providing a paint film.

2024 aluminum alloyed with copper for applications that require high strength to weight ratio and strong fatigue resistance. Pieces of flat sheet metal typically referred to as blanks is fed into a sheet metal stamping press that uses a tool and die surface to form the metal into a new shape. It increases the metal sheet s surface area by squeezing the metal rather than exposing it to tension. Typical sheet metal thicknesses used in stamping are 0 001 in.

Stamping includes a variety of sheet metal forming manufacturing processes such as punching using a machine press or stamping press blanking embossing bending flanging and coining. Aluminum is a silvery white metal that has comparable strength to carbon steel but at roughly one third the density. Aluminum metal stamping is a cold working process that utilizes work hardening of the material to accentuate the metal s beneficial qualities. Providing sheet metal having opposite major surfaces and being made of steel aluminum or any other desired elemental or alloyed metal.

Aluminum parts that have been stamped provide greater physical strength than unworked raw aluminum material. Laminating the paint film onto a major surface of the sheet metal to form a painted sheet metal laminate comprising a first portion and a second portion. Since the sheet metal has thickness of 019 inches there must be a gap between the two dies that allows the sheet metal to fit during the stamping process. When aluminum is ironed it almost compressively flows like a hot liquid down the wall of the die cavity and punch and it shines to a mirrorlike surface finish.

This alloy is very ductile and malleable making it ideal for precision stamping processes.
