British company PWM, which
designs and manufactures
high-performance cold welding
equipment, is stepping up production
of its custom-made dies for welding
two different sizes of non-ferrous wire
and rod.
According to PWM’s managing
director, Steve Mepsted, more wire
manufacturers are looking for cold
welding dies capable of bonding
different sizes of wire during the wire
drawing process.
“We custom make dies specifically
for this application, enabling
manufacturers to weld different wire
sizes together extremely quickly
when changing spools, ” said Mr
Mepsted.
“Manufacturers can, for example, weld
2.5mm diameter wire to 2.7mm
diameter wire without disrupting
production, which has considerable
cost benefits.”
PWM’s double cavity dies are
hand-made by skilled engineers in the
company’s own workshops to
stringent quality standards using top
quality tool steel.
Although most of the recent demand is
for dies to weld wire sizes with
diameters within the range 0.3mm to
1.8mm (0.011"-0.071"), PWM has
made dies to bond materials with
larger diameters, for example 8mm rod
to 9.5mm rod.
PWM offers manufacturers a fast
turnaround and can provide
custom-made dies within two weeks
from receipt of order. Standard sizes of
die can be supplied within 24 hours.

Leading cable manufacturer Tratos has
created Tratos Nuclear®, a low voltage
power cable specifically designed for
use in nuclear power station cranes.
Manufactured from a tinned flexible
conductor, with HEPR insulation and
EVA sheaths for strength and
durability, Tratos Nuclear has been
designed to give the best possible
performance where tensile strength,
bending radius, temperature and
operating speed are paramount.
The cable has an operational speed of
200mt/min and working ambient
temperatures of -25°C to 90°C.
Tratos Nuclear has undergone
extensive and vigorous testing and is
approved by IMQ to BTS 74 068000,
NF M 64-001, CEI EN 61074 AND UNI
ISO 4650.
Tratos Nuclear is one of the range of
cables for moving applications from
Tratos, which include mono-spiral and
multi-spiral reeling, basket reeling,
festoons and spreaders.
The cables supply power, control and
signalling functions.
