The ultra-smooth layer of diamond on a tungsten carbide die ensures the smoothest wire surface that is possible today. The VNT NCDC Nano diamond coated wire drawing dies are perfect combination of large-size availability of tungsten carbide and the ideal surface properties of randomly oriented synthetic diamond.

VNT NCDC Nano Diamond Coating Wire Drawing Dies

VNT NCDC Nano diamond is Chemical Vapor Deposition polycrystalline diamond material and manufactured by means of a diamond synthesis technology in which a low pressure reactor is used to combine a thermal or plasma activating agent with a gas-phase carbon to produce a chemical reaction which results in polycrystalline

Hole size range

Semifinished:From 0.010mm to 0.800mm

Finished:From 0.020mm to 1.200mm

Applications

hard metal fine wire e.g. tungsten, molybdenum & stainless steel.

Maintenance-free (no recuts, easy handling)

Exceptional durability

Low friction coefficient

High diameter accuracy

Available even for large diameters

Benefits

Improved diameter stability

High machine uptime

Reduced energy consumption

Excellent wire surface

Maintenance and cost

Diamond coated dies do not need to be recut and are simply discarded after use, reducing logistics and stock-keeping costs; additional savings are provided by not having to return the product for refurbishing.

The ultra-smooth layer of diamond on a tungsten carbide die ensures the smoothest wire surface that is possible today. The diamond coated die is the perfect combination of large-size availability of tungsten carbide and the ideal surface properties of randomly oriented synthetic diamond.

Cost differences vs. TC dies are quickly offset due to lowered running costs (lowered cost of ownership), you will start saving money from the start!
