“It has been a great opportunity for Tehno
World to collaborate again with battenfeld-
cincinnati, because we have reached for new
horizons in our field of activity. battenfeld-
cincinnati is a reliable and valuable business
partner for us with whom we have worked in
the past to develop our production capacity.
battenfeld-cincinnati has demonstrated the
high quality of its service and products while
helping us to develop further and raise our
standards of technology and flexibility,” says
Ing. Iustinian Pavel, Director of Tehno World.
The 1.2 m line produces pipe in the pressure
classes SDR 11, SDR 17 and SDR 26 and was
introduced to Tehno World’s customers at an
Open House event in October 2015.
The line is equipped with a solEX 90-40 as its
main extruder and a uniEX 45-30 as co-ex-
truder. Both operate with a high level of effi-
ciency, thanks to their AC drives, optimized
screw geometries and air-cooled, bi-metallic
barrels.
For the addition of color stripes, battenfeld-cincinnati deliv-
ered a small, space-saving coEX 30-25 co-extruder, installed
on a die trolley with a swivel arm for easy movement.
The new large-diameter line also includes some FDC (fast di-
mension change) components: The pipe head is equipped with
an adjustable die aperture, which consists of a conically
shaped mandrel and an outer sleeve moving in longitudinal
direction. It covers pipe diameters from 900 to 1,200 mm and
A 1.2 m pipe with color stripes produced on the battenfeld-cincinnati line
- with an extension – also diameters from 500 to 800 mm
(SDR 11 – SDR 26). The FDC components are completely inte-
grated in the BMCtouch extruder control.
The helix 1200 VSI-TZ+ pipe head re-
duces sagging and pipe ovality for thick-
walled pipes, even at high line speeds,
thanks to its two-step distribution con-
cept. The active intensive melt cooling
and inner pipe cooling operate mainly
with ambient air, thus minimizing oper-
ating costs and maintenance require-
ments.
The internal pipe cooling also reduces the
cooling length, which is of great impor-
tance for Tehno World due to limited hall
space. With the new line from batten-
feld-cincinnati, they can run 1.2 m pipes
(SDR 17) with throughputs above
1,500 kg/h and a cooling length of less
than 40 meters.
The cooling section includes two vac-
Stream 1200-6 vacuum tanks and four
coolStream 1200-6 cooling tanks and is
complemented by the rest of the line
components: haul-off (pullStream R
1200-10 VEZ), start-up aid (startStream
AFH 60), cutting unit (cutStream PTA
1200) and tip table (rollStream RG 1200).
The line is controlled by the proven BMCtouch control with a
19” TFT touch screen, so that saw and haul-off can be oper-
ated via the extruder terminal. The control also includes the
option of remote servicing.
