Abstract

A method for producing a heat radiating plate, the method containing the steps of: finish cold-rolling an annealed material to obtain a strip; causing the strip to wind in the shape of a coil to prepare a coil stock; unwinding the coil stock by means of an uncoiler to obtain a strip; causing the strip to pass through a gap between the rolls of a leveler to correct the shape thereof; progressively feeding the corrected strip to a progressive die via a feeder to progressively press-working the strip to produce a heat radiating plate.
