Accurate sor ting equipment for high material purity MINGER Kunststofftechnik AG,

Ofner, CEO of Minger Kunststofftechnik AG. The Purity Scanner Advanced convinced on the grounds of its future- orientated measuring principle, and due to sorted, pure material. “Worldwide, we are the first company that uses this technology for recycling,” said Mr Ofner. During the production of raw or recycled granulate, the plastic material can be contaminated by black spots, foreign particles or fine metal abrasion. These impurities are eliminated by the Purity Scanner Advanced. The inspection and sorting system combines X-ray and optical technologies to detect contamination inside the granulate as well as on its surface. Transparent, diffuse and coloured materials are reliably inspected for purity. Contaminated granulates are detected and automatically sorted out. The result of the purity testing is significant because, in an extreme case, unusable material can be made usable again. “The material does not contain foreign particles and the quality is improved up to 100 per cent,” explained Mr Ofner. The Sikora device is combined with an intelligent processor system that analyses and visualises the sorting. For Minger, statistical evaluation of the detected contamination sorted by number, size and frequency as well as an image gallery of contaminated granulates detected by the optical cameras and X-ray camera are of particular importance. All information is automatically saved and available in Excel format as well

Switzerland, is a specialist in the reprocessing of thermoplastic poly- mers, especially in the area of high- performance polymers. Since 2018, the family-owned company has been using the Purity Scanner Advanced on- line inspection and sorting system from Sikora. For the production and processing of polymers, the highest purity of the materials is essential and a crucial characteristic for the quality of the final product. The requirements on purity are accordingly high, especially for sophisticated materials which, for example, are used in the cable, medical, aerospace and food industries. Minger has been active in the recycling business for over 30 years, and produces plastic granulates as customised compound or as clean and pure regranulate, which is reprocessed as a service. The company relies on a sustainable recycling concept for an optimal material cycle. The application of innovative technology in the reproducing lines to ensure quality and process optimisation is a matter of course for the Swiss manufacturer. The company uses Sikora’s Purity Scanner Advanced for inspection and sorting of plastic material. “For our technical polymers and high-performance polymers – such as fluoroplastic, PEEK, polyamide, polyethylene or polypropylene – this quality approach was relevant for supplying first-class material,” said Bruno

as image files. Other recorded data includes the possible duration of the order, material type, throughput and rejection rate. This way, full traceability is possible after a project has been completed. “We use the production data as reference for future orders,” said Mr Ofner. “Furthermore, we forward the information as a final report to our customer, who receives absolute technical transparency about his product and the production process.”

Chamfering and end processing machines BÜLTMANN chamfering and end processing machines are used for facing, chamfering and turning. Other key data is available to the user as well as a high degree of automation and flexibility in design. The machines are all individually tailored to the customer’s requirements. Both fully automated and simple manual designs are possible. even for low capacity requirements. The machines and installations can also be combined with mechanical or optical testing devices, irrespective of the end machining, in order to verify or document the desired machining quality, as just one example. Features such as process monitoring and advanced applications can also be integrated.

This results in tailor-made, customer- specific solutions for high-performance requirements – eg within complete fin- ishing lines or as stand-alone machines,
