Blanking of 4mm SS Strip 1

[5107866]

Does anyone know about the blanking of 4 mm SS strip.We have SS strip of 1250mm X 336mm X 4 mm. We would like to do blanking of this sheet (Blank size = 19mm X 300 mm). Is it possible to do blanking of this strip? What will be the machinery(capacity of press) & tools requirement for blanking this strip?

Ganesh,

Here is a formula I use to determine tonnage of the press.

F= .7(thichness)(cicumference)(UTS).

For your application using 304 SS and in inches

F= .7(.157 in)(25.12 in)100000lbs/sq in

F = 275958 lbs

F= 138 tons
