ND die, natural diamond die, wire drawing dies
The basic principle and cross-sectional view of wire drawing die:
1.Thick wire inlet: various metal wire;
2.Die/mould shell: stainless steel material under the general conditions;
3.Sinter setting: special metal power sintering structure;
4.Various diamond: natural diamond, man-made synthetic diamond, man-made crystal diamond etc..
Features of natural diamond wire drawing die:
Diamond is the hardest material in the world. It is the single crystal formed by
natural crystal without granule. Due to the supper hardness, the service life of
diamond wire drawing die/mould can be greatly improved which is tens or even
hundreds of times than tungsten carbide wire drawing die/mould. The operation
of die/mould changeover can be saved a lot of times, thus improving the
production efficiency. And because of high hardness of natural diamond, diamond
wire drawing die/mould is not easy to wear , which can improve the stability of the
diameter, circular degree and size of the wire products and surface smoothness.
The wide application of nature diamond wire die/mould greatly improves the quality
and production efficiency of wire products.
Advantages of natural diamond wire drawing die:
The surface smoothness is best, and the tension of die/mould and friction
force are minimum in the die/mould materials. It is recommended to make
the finished products die(outlet die), microfilament die and the die
required special brightness the surface of wire.
Applications of natural diamond wire drawing die:
This product is suitable for various high quality gold wire, fine tungsten molybdenum
wire, electromagnetic wire, copper-clad aluminum wire, silver wire, supper line
aluminum wire and other valuable products etc..
