EXTRUDER specialist Cincinnati
Extrusion has expanded its Alpha
standard extruder range, with the launch
of the Alpha 75-25B for technical profiles,
mini-diameter and corrugated pipes.
Similar to the Alpha 45 and 60 models,
the new single-screw extruder offers the
advantages of short lead time and high-
grade technology. With an output of up
to 120kg/h for polyethylene, 150kg/h for
polyvinyl chloride and 180kg/h for PC/
ABS blends, the extruder is suitable for
a wide variety of applications.
The standard equipment package for
the 75mm extruder with smooth feed
bushing and a processing length of 25 D
includes a screw, a control cabinet based
on a relay control system (SecuRe) and
a mobile, digital operator terminal.
Customers can choose between a
screw geometry suitable for HDPE, PP,
ABS, PS and PET, one for modified
hard PVC granulate and hard PVC with
filler content, and one for soft PVC
granulate (compounds with and without
filler content) that can also process TPE
blends.
Available options include melt pressure
and melt temperature sensors, a CAN
BUS interface and a UPS voltage drop
protection unit.
Cincinnati Extrusion also offers a
turnkey solution for customers requiring
a complete line for technical profiles,
which consists of an Alpha extruder, a
customised profile die and the Alpha
protech downstream unit. This unit
includes a 6m calibration table, a belt or
caterpillar haul-off for line speeds of up
to 20m/min, a cut-off assembly and a
tilting device. Control for the downstream
unit is provided by a PLC that features
six different languages, can be adjusted
to user-specific requirements and is
operated via a 6" touch-screen display.

HTI AG forms new
worldwide
extrusion group
IN 2008 the Theysohn Group
and the Technoplast Group were
incorporated by the stock quoted
Austrian technology concern High
Tech Industries AG.
This change of ownership was
followed by a phase of evaluation
of strengths and possibilities of the
companies as well as analysis of
customers’ requirements and the
global market changes of recent
months.
The company started 2009 with a
focus on implementing its values
of partnership and reliability, and
promoting its extrusion technology
as an ‘all in one’ supplier,
producing extruders, downstream,
tooling, screws and barrels. The
company concentrates on its core
competence – PVC extrusion, with
a focus on extrusion of profiles,
pipes and siding.
The company operates three
production sites with following focal
points:
Korneuburg, Austria – Theysohn and
Technoplast extrusion machines
Micheldorf, Austria – Technoplast
and Topf extrusion tooling
Salzgitter, Germany – Theysohn
screws and barrels

best control of the outside geometry.
Particular care has been given to the
vacuum control, which can automatically
change through a system linking the laser
control on the pipe outside diameter
with an electronic valve for vacuum
adjustment into the trough, in order to
keep the outside diameter constant,
even at very high extrusion speeds.
A thermostatic valve automatically
controls the water temperature.
