Breaking the 1,000kg/h production barrier in profile extrusion

can adapt its extruders to current market requirements. The Konos conical twin-screw extruder series – comprising the models 38, 50, 63 and 72 – is a compact and flexible machine series in its performance class. In profile production, Konos extruders cover an output range from 20 to 280kg/h. With the parallel twin-screw extruder series Argos 72, 93, 114 and 135, Cincinnati also caters to the performance range of 100 to over 1,000kg/h in profile extrusion. Specially designed to meet the requirements of the industry, these extruders feature a high moment of torque delivered by the durable, powerful four-shaft transmission system. Argos and Konos extruders are equipped with maintenance-free AC motors. These meet the demand for energy-efficient operation due to their high degree of efficiency especially under partial load. An efficient air power cooling (apc) barrel- tempering system works in partnership with Intracool, a closed-loop, maintenance- free and self-regulating screw tempering system. This has led to a reduced energy consumption of both extruder series by about 15% compared to conventional machines.

A record-breaking output of 1,000kg/h in profile extrusion has been achieved by two partner companies, Gruber & Co Extrusionstechnik GmbH and Cincinnati Extrusion GmbH. The two Austrian machine manufacturers, who formed a strategic alliance last year, achieved this feat using the Argos 135 from Cincinnati with the twin-strand die from Gruber to extrude 5-chambered profiles. A substantial factor in breaking the 1,000kg profile production barrier was the perfect combination of efficient apc barrel insulation and Intracool internal screw tempering with Cincinnati’s twin-screw extruders. The machine manufacturer has succeeded in optimizing its extremely versatile Polytherm

screws for the two extruders, Argos and Konos. This has enabled an even wider processing window and also led to a 10% increase in output. The Konos 63 achieves an output of 210kg/h, which constitutes a 5% increase, and the performance of the Argos 72 has been boosted by 10% to 250kg/h. The basic geometry of Polytherm screws currently covers 80% of all window profile applications. In specialized tasks, there is further scope for optimization of the screws following detailed analysis of specific user requirements.

Due to its experience from more than 7,000 conical machines sold to date, Cincinnati  An output of more than 1,000kg/h has been reached for the first time in the production of 5-chambered window profiles

Band saws from Italy FMB, Italy, has been producing band saw machines for metal cutting since 1982. The company’s present range consists of 29 models, covering cutting capacities from Ø100mm to 630mm, together with a complete set of solutions for material handling. The company states that the basic concepts of its machines have always been the same: quality, solidity and reliability. The latest models, introduced at the end of last year, have the same characteristics, and the changes they present are the consequence of technological progress. FMB srl – Italy
