The innovative LVC/PDH lubrication
system provides a high-performance
anti-friction coat, reliable lubrication
for the most demanding drawing
applications, allowing the highest
drawing speed with all steel rods/
wires, including mechanically descaled
uncoated 0.85-0.88 %C rod.
Applications include drawing of spring
wire, high-tensile rope wire, PC strand
wire, CO2 welding wire, plating wire,
cold heading wire, etc.
The LVC/PDH lubrication system
features automatic control of
lubrication parameters, including
lubricant pressure, temperature and
viscosity, enabling the use of standard
high melting lubricants (+220°C=428°F)
which are converted from solid into
liquefied state and instantaneously
deposited on bare rod, generating
exceptional thermal stability in all drafts
at the highest drawing speed, replacing
phosphate, borax and their wet
pre-coating substitutes, completely
eliminating rod residual moisture.
In operation, all these parameters
‘communicate’ together in a sensitive
and automatic multi-way interaction
to form a consistent exceptionally
adherent full-film anti-friction lubricant
coat, weight-adjustable, enabling
frictionless drawing by physical
separation of wire-die contact in all
drafts, eliminating friction heat, greatly
increasing die life, providing superior
surface quality and improved wire
ductility.
Typical applications with the LVC/PDH
coated rod: Output of 2.2 tonne/hour
with 5.5mm 0.83-0.88%C mechanically
descaled bare rod, in a ‘frictionless’
drawing application with die life of
200 tonnes/die in the first draft and a
die wear of 0.20 micron/tonne of wire
drawn in the last draft.
Spring wire is drawn from mechanically
descaled bare rod, without pre-coating
chemicals, at 18m/s (3,600ft/min);
5.5mm 0.72 %C rod drawn to 2.35mm
at 16m/s (3,200ft/min); 0.5mm 0.85-0.88
%C rod drawn to 4.22mm at 8-9m/s
(1,800ft/min).

Eraser’s model RT2S fine magnet wire
stripper will strip film type insulations
including Formvar, ML, enamel, varnish,
isonel, and more from 28AWG to 48AWG.
The conical wheels rotate at high speed to
generate frictional heat which softens the
insulation on the wire.
The machine features a strip length
stop for consistent strip lengths, a dust
take-off port for environmental safety
and close-up, multiple-wire stripping
capability.
The unit also cleans and polishes
leads of small electronic components
and removes oxidation and other
contaminants from leads as small as
0.0012" diameter.
