Maximum Thickness For Sheet Metal Stamping

All other factors influencing sheet metal forming we should recall that a sheet metal forming operation can always be.

Maximum thickness for sheet metal stamping.

Also the stretching and compression of forming can distort holes adjacent to a form or bend. Holes are best kept at least 2 times material thickness beyond the radius of a formed feature. Shearing material thickness range varies from 0 125 mm to 6 35 mm 0 005 to 0 250 in. Shears are used as the preliminary step in preparing stock for the stamping processes or smaller blanks for cnc presses.

The foil is pliable and can be readily bent or wrapped around objects. Shearing is a process for cutting sheet metal to size out of a larger stock such as roll stock. Corners may be sharp however to reduce tooling costs specify radii of material thickness or a minimum of 015. Sheet metal design guidelines are followed to design quality sheet metal enclosures.

2 to 1 for stainless 1 to 1 for carbon steel 0 75 to 1 for aluminum. Plastic deformation leaves some stresses locked through metal thickness. Notches and tabs should not be narrower than 1 5x the material thickness. Length of notches can be up to 5x length of material thickness.

This helps in delivering the product at low cost and faster timelines. Sheet metal is something between 0 154 to 6 35 mm thick standard household foil is typically0 016 mm 0 63 mils thick and heavy duty household foil is typically 0 024 mm 0 94 mils. All sheet metal design guidelines are very difficult to follow in complex sheet metal parts. A stamping press is a machine that houses the stamping tools.

Recommend corner radius of material thickness. A deflecting punch requires more tonnage to break through the material and again increases distortion. Sheet metal forming is quite common for making shaped components from soda cans to automotive car bodies. 2 metal forming process during stamping the material under the action of the external force the equivalent stress of the material in the deformation zone reaches the yield limit σs of the material but does not reach the strength limit σb so that the material only plastically deforms thus obtaining parts of certain shape and size.

It is customary to refer to a material below the thickness of 6 35 mm as a sheet and thicker materials as plate. Also watch out for punch deflection especially if you re working with small hole diameter to material thickness ratios. The rule of thumb in stamping design is to leave a minimum of 1 1 2 times material thickness between trimmed or perforated features.
