The Treffert Group (Bingen am Rhein, Germany), a supplier of masterbatches and specialty compounds, has added a twin screw extruder from Coperion (Stuttgart, Germany), a leader in compounding systems, feeding technologies, and bulk materials handling systems and services, to its production line. Treffert has installed the machine at its French facility in Sainte-Marie-aux-Chênes primarily for the production of masterbatches and concentrates for laser-based and other sensitive applications for customers in the medical technology, pharmaceutical, and automotive sectors.
First introduced at K 2013 in Düsseldorf, Germany, the ZSK 32 Mc18 smart extruder with 32-mm-diam screws is designed for easy cleaning, a key requirement in medical applications. Treffert also appreciated the extruder's safety features and ease of use, Coperion's Kathrin Fleuchaus told PlasticsToday.
"The screw shaft axes are 800 mm above floor level, allowing visibility of the entire extruder," says Fleuchaus. "The process section and all peripheral units are easily accessible by operators," she adds, and auxiliary units such as the side feeders and devolatilization systems can be mounted on extruder barrels using a swivel arm. "They can be operated from the floor without the need for stepladders, platforms, or overhead cranes, which improves operator safety," says Fleuchaus. The configuration also means that the peripherals do not come into contact with the floor and, therefore, are not exposed to potential contaminants.
