Diamond wire drawing die blanks and methods of making the same
TLDR
A diamond wire drawing die blank and method for making the same are provided in this paper, where a diamond die blank is formed by metering about one half of a metal powder required to form a shroud around a diamond into a die cavity, partially compressing said one half while forming a central conical depression in said powder, placing a diamond in the formed conical cavity, adding the remaining metal powder to the mold over the die and first compressed half, compressing the metal powder around the diamond and sintering said powder compactAbstract:
