1 natural diamond wire drawing die 2 superior quality and performance 3 good wear resistance 4 good finish surface

SUPREME natural diamond wire drawing die made with high quality natural diamond, undergoing rigorous selection process. It is high hardness, good wear resistance, suitable for high surface finish’s request to all kinds of wire drawing. Generally used for wire drawing dies’ diameter below 1.2mm.

Supreme Superabrasives Co., Ltd specializes in diamond and CBN related superhard material products and we have high reputation in the industry based on Zhengzhou, Henan province.

We research, manufacture and export  of PCD wire drawing die blanks / finish die, PCD/PCBN cutting tool blanks, PDC cutters for oil/gas drilling and mining bits, PCD/PCBN cutting insert, diamond micron powder and so on.

ND wire drawing die advantage:

 

Wire surface finish is best among all dies drawing;

Pulling force and friction force is the smallest;

 

ND wire drawing die application:

 

Used for fine or super-fine wires, or wires with advanced surface finish. Generally for tungsten wire, Electromagnetic wire, plated silver wire, stainless steel wire, alloy wire.
