Jinping Wire Die produces high performance natural diamond dies which are widely used to draw fine wires like magnet wire (normally less than 0.5 mm), tungsten wire and stainless steel wire (less than 0.1 mm).
Features:
● Precise die orientation
● Accurate die profile
● Highly polished finish from bell to back relief
● Accurately sized
● Straight & consistent reduction angle
● Maximum wear resistance
● Minimum die pull
● Excellent wire surface quality
● Hole diameters: 0.009 - 1.750 mm
