Cincinnati Extrusion to Present Leading Innovations at NPE
Cincinnati Extrusion’s appearance at this year’s NPE in Chicago (South Hall, booth
No. 18008) from June 22-26 will be all about Leading Innovations. The Vienna based
machine manufacturer will show a range of extrusion equipment including its brand
new KryoS pipe head, core element of the cutting-edge energy-efficient KryoSys PO
pipe extrusion line. Moreover, the company is planning six other exhibits of its ma-
chinery and components, as well as finished products fabricated with its equipment.
Besides the KryoS pipe head the displays will include:
Argos 72 parallel twin screw extruder for production of PVC profiles, pipe, sheet
Konos 50 conical twin screw extruder for PVC profile, pipe and co-extrusion pro-
duction that combines high throughput and performance with low-cost.
Alpha 45 single screw production utility for profiles made of thermoplastics and
small diameter tubing.
Profile die manufactured for the production of fenestration profiles.
Static screw display showing Cincinnati Extrusion design and engineering capa-
bilities in twin screw extrusion.
Samples of finished products, including fenestration profiles, siding, irrigation,
foam PVC sheet and natural fibre composites.
These exhibits highlight an important component of Cincinnati Extrusion’s capabilities:
Leading Innovations. Through strategic engineering, the development of the world’s
leading technology for profile, pipe and foam PVC sheet with focus on energy savings and
highest capability for investment.
High output extrusion for PVC profile producers
Cincinnati Extrusion offers the leading technology solution for parallel counter rotating twin
screw extruders, the ARGOS. The 72 mm diameter machine on display has a throughput
capacity up to 590 lb. (270 kg) per hour. The extruder has a 28:1 L/D ratio and the screw
design is specific to the high quality output required for fenestration. The machine is ro-
bust, easy to operate and economical.
The extruder is standard with six barrel zones, eight die-heating zones and one adapter
zone. Standard execution is with intracool water filled screws and APC® air cooled barrel.
The unit will be equipped with the latest EXcPRO-XP control system.
The ARGOS series for PVC profile extrusion is available in 4 sizes; 72, 93,114 and 135;
with production capacity up to 2200 pounds (1000 kg) per hour.
Extruder standard for Conical Twin Screw Extruders
Cincinnati Extrusion has produced conical counter-rotating twin screw extruders since the
1960’s and has maintained its leadership position for offering the latest technology for the
extrusion industry, as exhibited with the KONOS twin screw extruder.
The KONOS 50 machine on display has a throughput capacity up to 440 lb. (200 kg) per
hour. The extruder has a 15% longer processing unit and 15% larger nominal diameter
compared to previous designs. The extruder is standard with four barrel zones, eight die-
heating zones and one adapter zone. Standard execution is with intracool water filled
screws and APC® air cooled barrel. The unit will be equipped with the latest EXcPRO-XP
The KONOS series is available in 4 sizes; 38, 50, 63 and 72 mm; with production capacity
up to 1100 pounds (500 kg) per hour. Pedestal mounted execution for co-extrusion is an
available standard option on most sizes.
New benchmark for small diameter single screw extruders
The Cincinnati Extrusion series used for small diameters; single screw extruders for ther-
moplastic materials for profile, tubing, pipe and co-extrusion accomplished using the AL-
PHA technology platform.
The ALPHA 45 machine on display has a throughput capacity up to 154 lb (70 kg) per
hour. The extruder is standard with four barrel zones, four die-heating zones and one
adapter zone. The ALPHA 45 is displayed with a grooved feed bushing and the 28:1 L/D
processing unit. Standard execution is with nitride screws and barrel, discrete control
panel with Eurotherm 3216 controls and Vacon remote drive control, pre wired for CAN-
BUS for co-extrusion applications.
The ALPHA series is available in a matrix of three diameters 45, 60 and 75 mm, two L/D
ratios, 25:1 and 28:1 and two feed bush options – smooth and grooved. This matrix allows
for the widest processing window for the complete range of thermoplastic materials used in
Pipe die designed for high yields and energy effiency
As part of the revolutionary KryoSys polyolefin pipe production system, the KryoS pipe
head is the heart of the technology success and truly, a Leading Innovation for pipe pro-
The modified spiral mandrel distribution pipe head incorporates a temperature controlled
cooling section prior to the die set allowing for the reduction of the polymer melt tempera-
ture by as much as 25%. This reduction in melt temperature reduces the amount of sag at
the die exit. Additionally, the cooling of the polymer melt and the internal pipe cooling re-
duces the internal stress in the pipe wall.
The KryoSys pipe production system is available for pipe diameters from 110 to 2000 mm
(4” to 78”) with wall thicknesses up to 150 mm (6”) and above and production rates up to
3500 kg/hr (7700 lbs/hr). Typical reduction of cooling length with the KryoSys concept is
up to 50%. As an example, production of HDPE pipe with a 400 mm diameter and 36.4
mm wall at 2860 lb/hr (1300 kg/hr) production rate can yield energy savings of 186 kW
compared to typical pipe extrusion technology and shorten the cooling length by 45 m to
40 m in total.
KryoSys allows utilizing the energy removal from the pipe production to preheat the in-
coming raw material for a reduction in consumed drive energy of the extruder.
PVC Profile Extrusion Dies
Examples of fenestration dies from key suppliers of profile tooling will be on display.
Excellence in screw design
Extruder efficiency is as much a function of screw design as any other factor. Cincinnati
Extrusion is a leader in designing single- and counter rotating twin-screw systems for op-
timum production. The company, which designs screws for competitors' machines as well
as its own, can provide specific screw geometries for all types of single- and twin-screw
extruders. Cincinnati Extrusion is exhibiting sets of counter-rotating twin-screws, in parallel
and conical designs in a static display that highlights its expertise in screw design for pipe,
profile, siding, natural-fibre composite and sheet applications.
Finished products showcase process capabilities
To show what can be done with its extrusion technology, Cincinnati Extrusion is exhibiting
products that have been fabricated with its extruders and tooling.
Examples of PVC profiles for fenestration, PVC siding, natural fiber composites and low
density foam PVC sheet are scheduled for the exhibit.
The KryoS pipe head is the core element of the KryoSys
pipe extrusion system, which features energy savings of up
to 30% and a reduction of the cooling length of up to 50%
