Abstract
PURPOSE: To control accurately and precisely a weight of nobel-metal blank, by press-punching a strip of high purity nobel metal into a blank having required shape and dimensions after a press-rolling said strip.
CONSTITUTION: A strip of high purity noble metal is made by press-rolling into a strip having good dimensional accuracy in sheet thickness and is made successively by press punching into a blank having required shape and dimensions. The variance in the amount of weight of the nobel metal blank of several W several hundreds grams can be restricted to ≤ about 10mg, and the noble metal blank, stable in weight and quality, is obtained.
