Coperion and Lummus Novolen Technology
In a recent test series performed in its test lab at Stuttgart, Germany, Coperion together with the technology licensor Lummus Novolen Technology demonstrated the wide range of possible applications for the proven Coperion ZSK twin screw extruder series. Within the scope of tests, various Polypropylene pellets with extremely low melt viscosities were successfully produced. This so-called meltblown Polypropylene (PP) forms the raw material for the production of nonwovens, which are mainly used as filter media in medical protective masks.
Coperion and RenCom AB
Swedish innovation company RenCom AB has chosen Coperion’s state-of-the art twin screw extrusion system to enable the production of RENOL®, an innovative thermoplastic biomaterial that can be used to replace fossil-based plastics. Following comprehensive studies in Coperion’s extrusion test lab in Stuttgart, Germany, RenCom and Coperion were able to further develop the processing of this lignin-based material and transform it into durable, reusable biomaterial by using the ZSK twin screw extruder technology. RenCom will be able to produce up to 1,000 tons RENOL® per year starting late 2020.
New control technology
Coperion K-Tron is pleased to introduce the newest generation of the time-tested KCM feeder controller. The newly redesigned KCM-III has a variety of new features, including a larger 5-inch LCD screen with an improved user interface, context-sensitive help, stainless steel enclosure, and built-in Ethernet capability with optional Wi-Fi. With Ethernet capability (wired or wireless) the KCM-III can be accessed via a user-friendly feeder web page that includes a full feature user interface. In addition, the KCM-III is ready for Internet 4.0 functions such as predictive maintenance, electronic service options, overall equipment effectiveness, outlier detection, machine optimization and much more.
Profitable Recycling and Upcycling
Aurora Kunststoffe, a company located in Neuenstein / Germany and since end of 2019 member of MOL Group, is demonstrating how plastic processors’ production waste can be recycled and upcycled profitably. This producer of recompounds uses rejected parts accumulated from plastic components manufacturing as primary raw material and processes it into recycled, new-product-quality plastic compounds. After a major fire in their production area in 2017, Aurora Kunststoffe decided once again to rely on ZSK twin screw extruders from Coperion. Those three ZSK 45 Mc18 twin screw extruders have been in successful operation since early 2019, and with their high throughputs and their reliability, they have fulfilled every requirement that Aurora Kunststoffe needs for their innovative business plan.
Visionary Multi-Layer Film Recycling
Coperion GmbH is implementing a closed-loop concept for the production of flexible multi-layer film. Recycling multi-layer film has long posed a challenge since such films can only be reclaimed in very complicated ways and not without residues. Now, however, Coperion has developed a closed-loop approach solution in which up to 100 percent of multi-layer film production waste can be re-processed and fed back into the production process in a closed-loop. For a concrete project Coperion will deliver a recycling system, including bulk material handling, high-accuracy feeding from Coperion K-Tron, and the heart of the system, a ZSK Mc18 twin screw extruder.
