  Abstract: A progressive forming method is applied where stamping is continuously executed to 
  produce the rectangular fins of the plate fin heat exchanger. This process produced the fins 
  one-by-one instead of by bundles. In order to produce a fin having a depth of more than 6.0 mm, 
  the forming load and effective stress according to the size of the edge radii of punch and die are 
  predicted by forming simulation. Furthermore, the process of forming the second, as well as the 
  third,
