www.vapour-degreasing.com PRODUCTS & PROCESSES Axalta and TAU Industrial Robotics shed light on curing Insight and control into the coating process for electrical steel in e-mobility and renewable energy electric machines Users of Voltatex® insulating materials from Axalta, a leading global supplier of liquid and powder coatings, can now exclusively have access to the newly-developed LILIT® (Light In-Line Insulation Test) to monitor and document the drying consistency of the coatings produced. LILIT is a product of Italian technology company TAU Industrial Robotics. It provides reliable and accurate test methodology of functional polymers, such as those used as synthetic resins in coatings. The test ensures the coatings maximise their full quality potential at the optimum degree of polymerisation. High-performance technical machines such as electrical motors require accurate and comprehensive quality control of the ideal curing of insulating materials during the manufacturing process. Modern composite technologies including self-bonding processes for the production of electric motors for e-mobility are particularly sensitive. These require superlative quality control in order to pass the high demands on reliability and cost efficiency. Before the development of LILIT, polymerisation processes could not be monitored and documented adequately. A non-contact, non- destructive in-line test method for coil coating – as standard in the electrical steel coating process – was not technically feasible. Christoph Lomoschitz, Global Product Manager for Axalta’s Energy Solutions business, says, “We can now do away with time-consuming quality checks at the beginning and at the end of the coated coil process. These didn’t bring much information 62 APRIL 2019 about the degree of polymerisation because of local fluctuations in drying conditions across the entire coated coil. So by bringing TAU’s LILIT technology to our customers, we are making their quality control much better and more efficient, as well as improving process accuracy and overall electrical steel quality.” Filippo Veglia, Chief Commercial Officer TAU Industrial Robotics, says, “We are committed to bringing higher performance, improved sustainability, and meaningful insight to the core functions of e-mobility and renewable energy. We are thrilled to work with Axalta to bring real-time, non- contact, in-line quality control of curing processes to the electrical steel industry.” Axalta is exhibiting the full range of its Energy Solutions products at the Coil Winding Expo (CWIEME) in Berlin, Germany, from 21 to 23 May 2019 on stand A19, Hall 3.2. Visitors will have the opportunity to see a demonstration of the new LILIT technology and discuss with TAU on stand.
