Extrusion 6-2018

29 Extrusion 6/2018 Pipe Extrusion, Periphery High-speed coiling of flexible pipes in small coils and simultaneous double cutting of rigid plastic pipes. FLASH 450 is the latest member of the Sica automatic coiler family. Modern designed, safe and user-friendly, it is suitable for packing corrugated PVC, PE and PP pipes from 16 to 25 mm diameter in short length coils covered with stretch film. The coiler has three reels with centralized adjustment controls, an electronically controlled film dispenser, universal film cutting systems and variable-geometry reel unloading device. Its innovative packaging method (Patent PCTIB2016052545) reduces the quantity of film used with respect to traditional systems available on the market (up to -30 percent). ables cutting with chamfering unit and knife without producing chips inside the pipe. Particularly suitable for PP lines, equipped also for the production of double-joint pipes, it performs simulta- neous double cutting cycles automatical- ly. This system allows perfect synchroni- R esearch and development has also led to the DUET series’ innovative method for cutting plastic pipes that makes possible reaching very high pro- duction rates (patent EP2008749) with reduced energy consumption, ease of use and control.

Moreover, the ma- chine is equipped with specific anti-wear tools to guarantee exceptionally high and lasting quality of the cutting/cham- fering process. The logic control system also offers ‘on the fly’ cutting capabilities (Sica patent EP129515), optimizing the use of the effective stroke to increase further output in terms of the number of cuts/hour. Based on electro-pneumatic design eli- minating all possible problems linked to the use of hydraulic actuators and hy- draulic power packs, it is configured to optimize total energy consumption.
