Reliable and prompt service
Teknodiam produces natural and polycrystalline diamond dies for all applications,
including drawing dies, shaped dies, wire extrusion nipples, special profile dies, as well
as the component parts of dies in natural or polycrystalline diamond.
Teknodiam is able to produce dies with even the most complex of profiles. Customers
are provided with a reliable and prompt reconditioning service for worn dies.
The drawing angles and length of the cylindrical part are ground to the exact
measurements requested, maintaining correct die geometry.

Lubrication is one of the crucial factors for
the quality of the drawn wire. Interrupted
lubrication in the steel wire drawing
process causes an increase of surface
tension in the wire, strong pressures
inside the die, rapid die wear, breakage
of the drawing nib and consequent non-
programmed interruptions in the wire
drawing process.
In order to avoid these problems, Koner
has studied a new concept line of
drawing dies – K.340 and K.370 pressure
drawing die (patented worldwide),
specially constructed and designed
to greatly improve lubrication in dry
drawing of steel wire.
With its revolutionary concept, drawing
dies becomes a real dismountable
drawing tool, adapted to meet all
operating requirements.
For wet drawing the K.320, with its
particular inside geometry, gives
optimum wet drawing process
characteristics and is also a great
economic saving.
The K.340/K.370/K.320 methods provide
considerable operating advantages:
production at maximum drawing speeds
less machine down-time for die replacement
better and more homogeneous wire quality
wire drawing under optimum quality control
nib life increased by 30% and more to traditional dies
overall costs reduced by around 40% (you only change the nib, not the entire die)
application of the requested quantity of lubricant coating to the wire
better wet or dry re-drawing operations
the overall dimensions of K.340/K.370/K.320 tools are the same as for traditional
dies
savings on transport – even large quantities of nibs can be delivered rapidly in
small packages directly to customers
elimination of die rejects and the accumulation of no longer useable drawing
dies in the warehouse, return can be gained from the sale of worn tungsten
carbide parts
