Drawing Dies
Drawing dies are typically made of tool steel, tungsten carbide, or diamond, with tungsten carbide and manufactured diamond being the most common. For drawing very fine wire a single crystal diamond die is used. For hot drawing, cast-steel dies are used. For steel wire drawing, a tungsten carbide die is used. The dies are placed in a steel casing, which backs the die and allow for easy die changes. Die angles usually range from 6–15°, and each die has at least 2 different angles: the entering angle and approach angle. Wire dies usually are used with power as to pull the wire through them. There are coils of wire on either end of the die which pull and roll up the wire with a reduced diameter.

Famous quotes containing the words drawing and/or dies:
“... you can have a couple of seconds to rest in. I mean seconds. You have about two seconds to wait while the blanker is on the felt drawing the moisture out. You can stand and relax those two seconds—three seconds at most. You wish you didn’t have to work in a factory. When it’s all you know what to do, that’s what you do.”
—Grace Clements, U.S. factory worker. As quoted in Working, book 5, by Studs Terkel (1973)
“From cradle to grave this problem of running order through chaos, direction through space, discipline through freedom, unity through multiplicity, has always been, and must always be, the task of education, as it is the moral of religion, philosophy, science, art, politics and economy; but a boy’s will is his life, and he dies when it is broken, as the colt dies in harness, taking a new nature in becoming tame.”
—Henry Brooks Adams (1838–1918)
