Sica celebrates 50
th
anniversary
with open house event
SICA, which recently celebrated its 50
th
anniversary, has organised an Open
House at its factory and invited extruder
and corrugator manufacturers and pipe
producers from all over the world to visit.
Among the 15 machines on display
were a swarfless cutting machine for PE
pipes up to 2,500mm; a cutting machine
for cutting and chamfering without
removal of material for PVC, PP and PE
pipes up to 160mm; an electric belling
machine for PVC pipes up to 200mm;
and a multi-belling machine for PP
sewage pipes up to 200mm.
The first (TRK/C 2500) works in an
extrusion line, and it cuts up to 180mm
without material removal. Sica’s solution
completely avoids all the problems and
the major inconveniences that result
from cutting with production of chips
and dust and from their subsequent
collection and management.
The second (TRS 160W) has been
specifically designed and assembled
for cutting and chamfering PP and PVC
pipes without material removal. This
model cuts pipes from OD 32mm to OD
160mm in extrusion lines. The system
can also be realised for saws up to OD
500mm. The bigger the pipe, the higher
the cost savings due to material savings.
The new system does not need a
vacuuming system or material recycling
operations, provides superior chamfer
quality, requires less maintenance,
and maintains a clean environment.
Furthermore, the pipe is clean to be
heated again in case of socketing.
The third (Unibell1 200 JRE) has
an IR-SW short-wave oven and is
characterised by the electromechanical
movement of the forming carriage and
the complete elimination of hydraulic
drives, also for the Rieber System (fully
pneumatic). A screw jack, connected
to a latest generation brushless motor
with resolver, allows quick and precise
mandrel positioning in a closed loop with
high mechanical efficiency (up to 70 per
cent) and very low noise level. Without
the need for oil cooling, this solution also
allows a considerable reduction of water
use. Moreover, with the elimination of
hydraulic movements any possible oil
leakage into the environment is avoided
and ordinary maintenance is reduced.
Both the heating system (IR-SW oven)
and the implemented forming carriage
drive lead to a high level of process
energy efficiency: the machine uses
energy only when strictly required,
during the pipe heating phase and for
the duration of the carriage movement.
The consequences are faster return
on
investment,
greater
market
competitiveness and greater respect for
the environment.
The fourth (Everbell4 200 PSP)
has been completely rethought and
modernised. It presents innovative
features such as pipe heating in a single
IR-SW oven, and both mandrel and
flange electromechanical movement.
This assures high speed with accurate
positioning of the belling tools, easy
process parameters setting from
operating panel, high energy efficiency,
very low noise level, and high system
reliability. Since it sockets PP pipes,
it is equipped with the Permanent
Socket Profile feature. It assures the
repetitiveness of the process and the
shape of the socket over time.

Eaton delivers 1,000
th
tube forming machine
EATON’S hydraulics business has
announced the delivery of its 1,000
th
Walform tube forming machine, to its
long-term partner Hyflexar. The machine
is the new M-WF385Xplus model – the
fourth generation of the compact and
innovative tube forming machines.
Close cooperation between Eaton
Walterscheid and Hyflexar, which
became a certified Eaton distributor in
2012, goes back 17 years. With twelve
branches throughout Germany, Hyflexar
offers a broad spectrum of products and
services for hydraulics, hoses and fitting
technology. Along with a diverse range
of components, it provides advice and
fabrication in its own branches as well
as installation kits, machine rentals for
in-house assembly and training courses.
“We have been enthusiastic Walform
users for more than 15 years,” said
Heinrich Motyka, general manager
at Hyflexar. “Right now we have 13
machines in active service. Reliability,
safety, efficiency and ease of use are
the most important factors for us.”
The Walform tube forming system
was introduced in 1995 and has since
become an established product within
the hydraulics industry. The new
M-WF385Xplus machine features an
intuitive control panel and integrated
light barrier in the tool holder. The light
barrier, which can be manually enabled
or disabled, helps reduce cycle times.
Additionally, eliminating the need for two-
hand operation when the light barrier is
active allows the operator to optimise the
work sequence, resulting in a faster and
more efficient process with less effort.
Other new features include a switch for
the tool change position, energy-efficient
demand-driven/temperature-dependent
fan control, integrated noise optimisation
and a resettable counter on the control
panel.
The tube fabrication process generates
a contour that reduces tightening motion
to at most one-sixth of a turn. In addition,
the applied force required is only 75 per
cent of what is normally needed with a
direct assembly cutting ring fitting.
