ABSTRACT:
A method for forming heat exchanger plates comprises formation of a fluid flow channel along the edges of a sheet metal strip or blank, and formation of a pair of raised end bosses. The raised end bosses are elongated in the longitudinal dimension and are formed within the final width dimension of the plate so as to avoid the need for trimming of excess material along the edges of the plate. The method generates less scrap than prior art processes using progressive stamping, and also permits variation of the plate lengths.
