EXHIBITION PREVIEW | K2022


Above: Isra’s DualStar can switch between surface and print inspection – so both can be done with a single system


allows the user to switch between ‘surface’ and ‘print’ inspection depending on the job. This makes it the only solution to combine inspection of unprinted foils, laminates, and coatings with that of printed material in a single system, says Isra. This saves the converter or laminator considerable investment costs, as they only have to choose one system. The surface inspection component detects and classifies all relevant defects when making unprint- ed, transparent, opaque, dyed and translucent web material. For printed material, it continuously checks the quality of the printed image, lamination and coating, to ensure process optimisation. Cloud Xperience combines cloud computing with intelligent analytics tools. It stores data in a central location while enabling continuous status monitoring of production processes and inspection systems. Thanks to a self-learning, AI-based cluster


function, it can collect, save, sort and classify image files in the cloud. This allows defect patterns to be differentiated from one another and classified more quickly and reliably, simplifying system setup and potentially reducing the time needed to ramp up production. � www.isravision.com


Right: Micro- cell foaming technology from Promix is available for new extrusion lines or as a retrofit


Promix Solutions will present solutions for mixing, foaming and cooling of polymer melts – helping to save raw material costs, reduce carbon footprint and increase production capacity. For manufacturers of light foams – such as XPS,


XPP, XPE and XPET – Promix will show how P1 cooling mix technology can be used to raise mechanical properties and lower foam densities. Promix Microcell Technology creates a microcel- lular foam structure in the polymer by adding atmospheric gases (N2


and CO2 ). This reduces


product weight by 20-50%, which reduces raw material use. The saved plastic also helps to lower CO2 emissions. The fine-cell foam structure helps to boost

mechanical properties. In the case of films and sheets for packaging, a homogeneous, fine-cell structure is essential – be- cause the gas bubbles are later deformed again during thermoforming. If cells are too large, mechanical strength is weakened and – in the worst case – defects occur. Promix conducted in-depth research into physical foam extrusion during the Covid pandem- ic. It discovered that the previous cell size – averag- ing 100 microns – could be halved. The fine-cell structure leads to very good mechanical values, comparable to those of non-foamed trays of the same thickness. Tests have confirmed that weight savings of around 20% can be achieved without sacrificing mechanical properties. As well as packaging films, the technology is also suitable for sheets, foam core and blown films. Promix will exhibit relevant key components at K2022 and provide information on specific fields of application. The foaming technology can be used for many


raw materials, including PP, PE, PET, TPE, TPU, PA, hard and soft PVC and bioplastics. It is available for new extrusion lines or as a retrofit. � www.promix-solutions.com


At K2022, Sikora will introduce a scanner that inspects and sorts plastic pellets according to their quality. Purity Scanner Advanced is a modular system for


flexible optical online inspection and sorting of plastic material, which has three optical cameras and one X-ray camera. “Even the smallest, critical contamination is


reliably detected and sorted out by the system,” said Ralf Kulenkampff, head of sales for plastics at Sikora. “The detection and ejection of contami- nated pellets is perfectly coordinated.”
