“ ACID-FREE PROCESS FOR STEEL
ROD CLEANING & SURFACE
PREPARATION”
“New Way to Draw Steel Wire
in the 21st Century”
DCCD process features:
• Eliminates acid, borax and precoatings
• Zero energy consumption
• Direct drawing from bare rod with no
speed limitation, for H/C and L/C
• New Lubricant Viscosity Control
provides exceptionally adherent coating
• Adjustable lubricant residual
• Zero lubricant waste
• Recommended for severe drawing
applications (spring, rope, bead,
CO2 welding, PC strand, plating quality)
• H/C wire drawn at 18 m/s (3600 ft/min)
• Up to 8 times longer die life
• Exiting wire temp. 45°C (113°F)
• Greatly improved wire ductility

Plasmait has introduced the new
PlasmaAnnealer for continuous heat
treatment, degreasing and oxide removal
of stainless steel and nickel alloy wires up
to 5mm in diameter.
This new machine can be designed for
annealing, stress relieving or material
hardening applications featuring process
speeds of up to 300m/min.
Energy efficient, the high-speed
plasma-heating concept allows for
accurate targeting of mechanical
properties of the processed material.
The plasma heating is complemented
with an appropriate length dwell zone
for annealing of materials with extended
recrystallisation time.
Small and homogeneously distributed
grain combined with exceptional surface
condition improves material susceptibility
to cold working, which manifests itself in
better drawability and lower drawing die
wear rate of plasma annealed materials.
PlasmaAnnealer is equipped with a
vacuum system to ensure controlled inert
atmosphere and exceptionally low usage
of purging gas.
The manufacturer, who adopted plasma
annealing, has recognised the value from
low cost of ownership in comparison to
traditional tube or muffle furnaces.
The benefits of plasma treatment include
more than 60 per cent lower energy
use, up to 10 times lower purging gas
consumption, in addition to the savings
from dry, chemical-free degreasing and
surface cleaning. Increased annealing
speeds by the factor of 5-10 result in lower
capital expenditure in take-ups and pay-offs
and associated costs of maintenance.
PlasmaAnnealer suits applications
with demanding surface or annealing
requirements in the medical, precision
mechanical, welding, marine, aerospace
and energy sectors.
