TRADE SHOW PREVIEW PETplanet Insider Vol. 23 No. 10/22 www.petpla.net 51 The rPET approach: extended range and products The recyclable material par excellence, PET has been the focus of the industry’s development efforts for years. Such developments concern both the technology - presses capable of processing higher percentages of recycled resins - and research into new materials and applications. For several years now, all standard Sacmi IPS models have been able to process up to 100% rPET and up to 50% PET in recycled flake form. The in-press hopper to be presented by Sacmi at the K’ show allows for further acceleration on this front by increasing the flake share to 70-75%. The single hopper optimises the flakegranule mix without the complexities that stem from having to manage two distinct processing hoppers. This proposal offers process simplification, which Sacmi combines with intense Research & Development into the use of PET instead of other resins (for example, to replace the traditional polystyrene used in the dairy sector). Thanks to its skilled Rigid Packaging Laboratory team and their understanding of materials and processes, Sacmi will also preview some of its latest producible items - such as new yogurt cartons made of transparent PET - that are driving sustainability by opening up new opportunities from both a product and market perspective. CCM technology The ability to design new products - such as PET dairy cartons - stems directly from the specific characteristics of the compression process, such as the lower material extrusion temperature, the absence of both, the gate and the hot runners in the mould. This results in a greater freedom to manage recycled and/or high-viscosity materials and the ability to manufacture light, high-quality, high-performance products. In the context of key development trends in the PET sector, the K fair offers the opportunity to showcase the latest generation of controls on CCM cap presses, such as the CMFlow extruder which reduces total electricity consumption on the press by up to 9%. With a 35mm screw connected directly to the motor, and a footprint as small as 1 meter, CMFlow can process up to 200 kg/h of resin - the same as a conventional 75mm extruder. In-the-field tests have demonstrated up to 50% fewer black spots: all other factors remaining equal. In addition to the new extruder, Sacmi customers can count on nextgen CCMs able to mount the new Smart Pack, a digital package that incorporates on-board sensors and controls. These boost plant availability, extend the lifespan of its components and simplify the workers’ tasks by reducing process errors, says Sacmi. The vision system Classy AI Applying Artificial Intelligence to vision systems can result in cuttingedge product checks, which can potentially be extended to achieve improved, proactive process management. Integrated on the PVS156 preform vision system displayed at the fair, Classy AI is a new tool that lets manufacturers perform immediate classification of defect types via a user-friendly dashboard. It covers everything from the most common defects to those that would be extremely difficult to spot without the expert eye of a highly trained technician. The result of Sacmi’s R&D on the software and relative control algorithms, Classy AI lets users examine categories of defects: in practice, the operator has a dashboard illustrating the detectable defect types. These are grouped into ‘families’ (accidental, technological, decoration-OCR, measurements, specific), providing a clear overview of the area of the object affected by a problem and compiling quality statistics. If an issue arises, a specific icon comes on, indicating the exact defect type and the affected area. Moreover, the operator is provided with statistics and info on trends. AI helps to treat the defect not as a ‘mathematical’ association between an acquired image and certain parameters but identifies exactly what the defect is in terms of the main defect families and sub-families, arriving at further levels of specificity that register the product type, the size and the technological process in use. Proposed as an integral part of the PVS 156 preform control system, it is set to be integrated on all Sacmi CVS vision systems as part of a new approach that puts the human factor back at the center of the operator-machine-software ecosystem. www.sacmi.com +44 78175 32087 +34 676 986 962 sales@petmachinery.com petmachinery.com Looking to sell your used PET machinery?
