PWM introduces new cold welder
for strip and tape
UK company PWM, a
manufacturer of cold
pressure welding machines
and dies, is introducing a
new cold welder specifically
for strip and tape.
The ST40 air/hydraulic cold
welder can be used to join
non-ferrous strip and tape
up to a maximum width
of 45mm (1.772") and a
maximum cross sectional
area of 33mm² (0.0514
square inches).
The precision-engineered
die, designed and
manufactured by PWM’s
in-house team, produces
a reliable weld stronger
than the parent material
without loss of electrical integrity. Mounted on a trolley for
convenience and ease of use, the ST40 is powered by an air/
hydraulic intensifier and is easily activated by a foot pedal.
PWM will launch the ST40 cold welder at wire 2016.

Compounds launch
A NEW family of stress crack resistance compounds
has been launched by the inventors of halogen-free
compound technology Megolon®. Halogen-free
compounds continue to be used in more challenging
conditions in many markets.
This new series of compounds has been developed by
Mexichem Specialty Compounds, formerly AlphaGary, to
accommodate the use of power or energy cables in areas of
the world where climatic conditions are severe and above
the norm, such as the Middle and Far East, but can be used
anywhere these properties would benefit the finished cable.
The company has the analysis techniques to determine if
cable is cracked due to the extrusion process or from the
nature of the compound. Through that expertise, Mexichem
determined that more robust products for some difficult
applications were needed in the market.
This led to the development of a series of compounds
with higher tear strength at elevated temperatures as well
as a better resistance to environmental stress cracking
compared to standard Megolon grades. Megolon® S382,
S384, S386 and S387 are the first of a new generation of
HFFR compounds designed to meet these challenging
applications.
They offer the enhanced characteristics as well as an
excellent range of standard properties normally expected
with Megolon compounds.
