Extrusion International 6-2023

15 Extrusion International 6/2023 In-Line Wall Thickness, Concentricity, Outside Diameter and Ovality Measuring Solution for Single or Multilayer Tube & Pipe Applications Breathing New Life Into Plastics Against a global backdrop of growing awareness of the need to reduce the production of high volumes of plastics and optimize their management, the Intergov- ernmental Negotiating Committee established by the UN has declared that a legally binding agreement on plastic pollution will be established by the end of 2024. In fact, annual production of the latter has more than doubled in the past 20 years to 460 million tons, which, without proper and timely action, could triple by 2060. The Committee's final negotiations will therefore focus on steps to be taken to make a decisive breakthrough in terms of reduction, recycling and reuse. This is the context for the efforts of Bausano which, with its new E-GO R line, promotes the regeneration of plastics and waste, industrial and in-house, for extrusion under the banner of the circular economy. Specifically, the innovative E-GO R technology al- lows highly contaminated plastic materials, such as HDPE residues from containers for: milk, motor oil, shampoos and conditioners, soap, detergents, and bleach, to be fully reintegrated into production pro- cesses. Other examples include PP waste from lunch boxes, yogurt jars, syrup and medicine bottles, caps and LDPE waste from cling film, shopping bags and squeezable bottles. In fact, E-GO R extruders are ideal for recycling both light and highly humid materials, as well as heavy films and materials with low water content. Following crushing, the flaked and ground plastic is conveyed directly into the extruder by means of a force-feed system designed specifically for this type of use. In the process, volatiles and moisture are removed by a high-performance degassing system, which prevents the development of defects in the granule such as "air bubbles," caused by gases in the starting compound or formed in the extrusion steps. The extruded mass is then filtered and directed to the granulation head. In addition, constant speed, combined with advanced screw design, ensures the highest standards of prod- uct quality. Finally, the liquid ring or immersion cut- ting system completes the line. The E-GO R lines can also be fitted with the Smart En- ergy System, the patent-pending system based on in- duction heating of the barrel that meets the needs of optimizing production processes in plastics extrusion. Unlike traditional resistor-based systems, heating is done without contact by an alternating electromag- netic field, synonymous with maximum performance and superior energy savings of up to 35%.

The RAYEX ® S measuring gauge is now avail- able with embedded Webserver access as well as native communication protocols such as OPC UA, Ethernet or Profinet. No additional proces - sor or display units are required. However, when combined with the known USYS IPC 2e processor and display solutions and other additional measuring equipment such as ODAC ® laser diameter and ovality gauges, ultrasonic wall thickness and concen- tricity measuring systems, KW lump and neck- down detectors etc, the RAYEX ® S Series are also able to control entire production lines.
