how to calculate the general need clamping force

how to calculate the general need clamping force according to the perpendicular area of the product

Clamping force=clamping force constant × projection area of the product

i.e.  p = Wps

In which, P—- clamping force (t)

S—- perpendicular projection area on the platen (cm2)

Kp—clamping force constant (t/cm2)

Kp is listed in the following table 1
