After studying for years how to
make cost effective dies, Ajex &
Turner has developed diamond coated
dies, which are replacing PCD with more
wear resistance, an extremely smooth
surface with immensely low friction.
The dies are suitable for:
• Drawing stainless steel wire or carbon
steel wire up to 0.6%C
• Drawing aluminium or Al alloy wire
• Drawing nickel silver wire
• Drawing copper/brass tubes
• Drawing wire and compacting/
stranding copper and aluminium
Aluminium RBD processes make stronger
and better wire using low friction
diamond coated dies.
There is much better performance than TC
or PCD dies, made possible by improved
diamond die technology.
The die also gives a surface finish hold +0
tolerance for up to 500 tones (stainless
steel and carbon steel wire up to 0.6%C).
The price is two to ten times lower
than PCD dies (depending on the bore
diameter).
These diamond coated dies can be
used for wire drawing and compacting
copper/aluminium/aluminium alloy/nickel/
stainless steel, copper and brass tube and
it can be made from 3mm to 72mm.
For high and low carbon, Ajex & Turner
has developed pressure dies for a long
life. These dies are used for dry and wet
drawing, respectively.
With its revolutionary concept of
disassembling die, it improves lubrication,
gives 30 per cent more nib or pallet life
and produces higher quality wire.
The pressure dies contribute significantly
to an increase in drawing speeds and
improve productivity to the wire plant.
By using the pressure die, the re-cutting
or refurbishment is very much eliminated
and the wire drawing speed also increases
up to 50m per second.
The company claims that this perfor-
mance can only be achieved with Ajex
pressure dies and their drawing inserts.
The company also provides three-day
workshops to engineers and operators to
learn step-by-step maintaince of the die
for maximum utilisation and longer life.
The cost of the die plays an important
role, and Ajex & Turner has developed
many machines for die polishing and
re-cutting for carbide and polycrystalline.
Dies which are running one to three
shifts need periodic cleaning for smooth
performance and a long life.
For the same purpose the company has
developed a die cleaning solution with an
ultrasonic machine which is developed in
two parts for longer life.
