High-performance extruders and pipe dimension change systems

T E C H N O L O G Y

Extruder specialist Cincinnati Extrusion GmbH, Austria, manufactures the Monos range, available in six sizes with screw diameters from 45-150mm, and outputs ranging from 270 to 1,850kg/h. The extruders are suitable for all applications that demand optimised melt quality at low melt temperatures, and achieve an increase in output of approximately 30 per cent compared to their predecessor models from the Proton series. Featuring a 37 D long processing unit and a special Power Feed barrier screw with a Maddock compounding section, Monos extruders can achieve a particularly smooth surface in PE or PP pipes, as well as optimised product attributes in corrugated gas or water transport pipes from PE 100, PE 80 or PP. The bimetallic barrel, which is included as standard, and a special coating in

the feed zone of the screw, ensure a long service life for these extruder models. company also produces the IntelliChange pipe dimension change system. IntelliChange is available for a total pipe diameter range from40mm to 400mm in three sizes. Each The

› The new IntelliChange pipe dimension change system from Cincinnati Extrusion

is laid out to accommodate four different pipe diameters ranging from 40mm to 160mm, 110mm to 250mm, and 250mm to 400mm respectively, and all standard wall thickness gauges from 1.8mm to 32.1mm.

The complete system has a dual spiral mandrel pipe head equipped with a hydraulic die gap adjustment facility. In addition, it includes the appropriate set of dies, an adjustable calibration unit, a dual-chamber vacuum tank with rotating calibration sleeves, a haul-off with automatic adjustment and a standard saw with central clamping fixture. As all preparatory steps can take place outside the extrusion line, the line has to be stopped for no more than 10 to 15 minutes to effect a change in pipe dimensions.
