Extrusion International 1-2024

32 Extrusion International 1/2024 BLOWMOLDING • Die width 2,850 mm, with internal deckling system two times 350 mm • New MDO unit: maximum roll temperature of 160 °C, maximum stretching ratio 1:10 Horizontal slid- ing winder for up to 4 part bobbins MDO unit for mono-materials One key innovation featured in SML’s latest cast film line is the MDO unit, that is also designed for the manufacturing of easy-to-recycle mono-materi- al films such as MOPP, MOPE and MOPET. With this MDO unit, properties such as the film strength in the machine direction, stiffness and puncture resistance are increased even further, while the film thickness and elongation in the machine direction are signifi- cantly decreased. SML has streamlined the whole MDO process: The clean and straightforward design makes operation comfortable and provides sufficient space for mainte - nance offering easy access. New roller arrangement – tight stretching gap One of the main technical features of SML’s latest MDO version is the process-optimised roller-arrange- ment. The adjustment of the stretching gap takes place in a motorised fashion, making the operation and alter- nations for product changes quite simple. As the stretch- ing rollers have a diameter of 220 mm, the stretching gap can be kept narrow in a range between 50 and 200 mm (free length of the film between the rollers). While the distances between the stretching rollers can be re- duced to a few mm only. The positions of the nip rollers in the stretching area are adjustable too. This ensures an ideal stretching process of the film, independent of the defined stretching gap. Comfortable settings with SML’s new HMI Finally, all the process parameters of theMDO unit are digitally recorded and can be comfortably set and ad- justed with SML’s new HMI. SML’s new multi-purpose cast film line is available to customers for trials and sample production.

It is integrated into a complete filling line. The origin of the project "We need a new blow molding machine as soon as possible!,” the owner of the Cherkasy brewery company appealed to PET Tech- nologies. "The output of our filling line is 12,000 bottles per hour," he continued. The answer of PET Technologies was immediate: “We’ve got a solu- tion for you!” The characteristics of innovative automatic blow molding machine APF-Max 8 fully met all the require- ments of beer and soft drinks manu- facturer. • Output matches with the pro- duction line; • Quick integration with filling line of European production; • Simple logic of operating equip- ment process. The Cherkaske Beer brand was founded in the city of the same name
