P lastic & Composite Tube: P roducts & Manufacture
99 July/August 2007
Unison’s all-electric tube bending machines will revolutionise
your tube fabrication operations. Servomotor bending axes give
you complete software control of the process. You can bend with
enormous precision. Scrap is virtually eliminated! And anyonecan set-
up the machine automatically, and repeat configurations at will.
The all-electric machine will also slash your electricity costs, as it
only consumes significant energy when actually making a bend. On
a customer comparison with an equivalent hydraulic bender, our
machine consumed 90% less electricity!
Choose Unison - the inventor of the all-electric tube bender - and you
will see a genuine return on your machinery investment. We have a
large range of machines for 10 to 150 mm diameter tubes.
Tube bending,
as it shouldbe.

More productivity and precision… Lessset-up time and scrap
Extrusion system for
large-wall tube and pipe
Guill Tool & Engineering, USA, has
extended its new 200 Series extrusion
system to handle sizes of up to 20" in
diameter and up to 2" wall size thicknesses.
The new 200 series is a self-contained
extrusion system weighing as much as
7,000lbs.
The system has a patent pending mounted
track and cart for easy handling and
maintenance. The cart system can tilt the
die on-the-fly in order to compensate for
the catenary (sagging) effect caused by
gravity as the extrusion product exits the
equipment.
Cable, tube or pipe manufacturers that
require large diameter and multi-layer
jacketing will also benefit from the new
rapid advanced material flow of the 200
extrusion head and the support system,
without the rigging or support equipment
usually required by conventional systems
on the market today.
With Guill’s precision engineering, the 200
Series ensures thinner walls and closer
tolerances. This is important for larger
tubing sizes, where waste or scrap may
account for thousands of dollars in lost
revenue. Engineering for the closest tubing
tolerances results in huge material savings
for all users, according to Guill production
officials.
The company also manufacturers tips, dies,
and breaker plates.

Sabic Europe, The Netherlands, is a
supplier of pipe grades in bimodal HDPE
and various PP grades. The company’s
Vestolen P 9421 is a PP random copolymer
(PPR) grade used in applications such as
hot and cold water supply. This grade of
pressure pipes has been in use for over 30
years, which is claimed to be longer than
any other PPR pipe grade.
Vestolen P 9421 is available in a variety
of colours and contains a finely tuned
stabilisation package proven to be
fully effective against thermo-oxidative
degradation. Pipes produced from the
grade meet the requirements of the
commonly used ISO EN 15874 and ISO
3213 standards.
Vestolen P 9421 is easy to handle and
process using conventional extruders and
injection moulding machines. It is also
environmentally friendly and corrosion-
free.
