PWM’s
smaller
electro-pneumatic
EP500 rod welder, one of the company’s
best-selling machines, has a capacity of
5mm to 12.5mm (0.197" to 0.492") copper
and 5mm to 15mm (0.197" and 0.59")
aluminium.
PWM will also exhibit two portable air/
hydraulic powered models, the HP100
and HP200 for wire sizes 1mm to 6.50mm
(0.039" to 0.256") as well as a range of
manually-operated cold welders for wire
sizes 0.1mm to 5mm (0.0039" to 0.197").

Within one hour of starting a wire drawing
machine, the lubrication of the wire being
drawn starts to deteriorate. The level of
burnt lubricant and metallic particles
continuously increases in the die box
over time until the point of complete
lubrication failure can occur. Often the
results are reduced die life, stressing of the
steel surface or even reduced productivity
due to having to run machines at lower
running speeds to overcome the issues.
Traditionally the best method used to
overcome these issues is to regularly
replace the lubricant in the die box.
However this proves expensive as the cost
of lubricant consumption and the cost of
waste disposal is high.
The LCM800 series machine from PWT is
used to condition lubricant in the drawing
of steel wire. It allows high and low carbon
steel wire manufacturers to maximise
production by providing good lubrication
in the drawing process. The LCM800
machine can be used with calcium or
sodium-based lubricants.
The LCM 800 series machine takes the
used lubricant from the die box and
removes the burnt lubrication and metallic
particles in its specially designed magnet
chamber.
The remaining good lubricant is then
passed through a granulator system
which can adjust the mix of ne to course
granulated particles of the conditioned
lubricant allowing the customer to
optimise the lubricant performance in the
die box.
The LCM800 machines are located in
well-known wire producers. Depending
on wire drawing practices PWT has been
able to condition between 45 and 95 per
cent of the used lubricant. This means
companies reduce their purchase costs
and waste disposal costs. Die life is often
extended and in many cases higher wire
drawing run rates achieved. The overall
cost per tonne reduction adds signi cant
bottom line improvements for companies.

QEDWire Lines
Stand: 12A25
QED specialises in equipment for
heat-treating, cleaning and coating of
steel wire. Custom designed and built,
the high-speed lines are for galvanising,
Galfan®, patenting, annealing and oil
tempering processes.
Combining innovative design concepts
with 30 years practical experience, QED
has developed a range of products and
equipment that is both technologically
advanced and ruggedly dependable.
With a view to improved e ciency and
to minimise environmental impact, the
company has developed the dual loop
pressure control combustion system.
This system maintains a steady output
and close air-gas ratio. This patented
combustion control system is used on all
the company’s multiple burner furnaces.
QED has recently upgraded its proven
uidbed technology with proportional,
closed-loop feedback and mass ow
controls.
The Siemens PLC-based system provides
much higher thermal e ciency and
lower fuel costs than previous systems. Its
uidbeds operate from DV=120 to DV=240
and from 1.5t/h to 8t/h production.
The latest development in galvanising
furnaces is the advanced recuperative
technology mark 4 immersion burner.
This burner o ers dramatically higher
combustion e ciency from a double
pass pre-heat design with extended
heat-transfer area.
Constructed of stainless and high nickel
alloy steels, this modularly constructed
burner o ers an extended operating
lifespan and reduced maintenance.
