Interesting little facts on the history of
wire drawing and the use of drawing dies...
Historians are unsure about the exact timing
of the development of wire drawing. Some say it was invented over 4000
years ago in ??. Archaeological discoveries of drawing irons dating back
to the time B.C. proof that wire drawing started at least over 2000 years
In Germany, wire drawing started around 700
years ago. In the past, immense human strength was necessary to elongate
wires. Today, this is done by wire drawing machines: The wire runs through
several drawing dies of continuously smaller diameters. Mounted back to
back, this ensures the production of highly precise sizes of wires.
Drawing dies wear out over time. The abrasion of the wire causes indentations that lower the quality of the produced wires. A professional drawing die shop can polish the worn parts and repair the drawing dies so they can be used again as a bigger size die.
