Covestro, LEONHARD KURZ and Sumitomo (SHI) Demag will present a new concept for a wallbox for charging electric vehicles at the K 2022 plastics trade fair in Düsseldorf. The smart demonstrator combines great freedom of design and high functionality with more sustainable manufacturing in terms of both materials and processes. It visualizes sustainable charging with green electricity and its design embraces “vehicle-to-grid” concepts, i.e. using the vehicle battery as a buffer store that releases electricity into the public grid to compensate for power fluctuations. "With this concept, we want to show that a contribution to sustainability, CO2 savings, and green mobility can already be made in the production stage of such charging stations," explains Dr. Niklas Meine, head of the global project EV Charging Stations and Marketing Electrical Engineering and Electronics in the EMEA region at Covestro. Lower carbon footprint, flame retardant, and recyclable "The RE compounds and films used for the charging station therefore have a very low carbon footprint. At the same time, they are suitable for backlighting as well as for various design technologies and meet the strict technical requirements for charging stations," Meine explains. For example, Makrolon® RE is particularly flame-retardant and achieves a good 5VA rating (Yellow Card) in the UL 94 fire test conducted by the U.S. testing company Underwriters Laboratories Inc. (UL). It is also UL f1 listed and can therefore be used outdoors under water and UV exposure. Energy efficient manufacturing Customized design "Overall, the numerous design options allow for the customized design of the charging stations under economic conditions," sums up Martin Hahn, Head of Application, Technology & Innovation of the Plastic Decoration business area at KURZ. The focus lies on a very broad use of different decoration methods and also their combination, so that, for example, partial metallization can also be implemented on the design ring using hot stamping technology. "With the Wallbox Design Demonstrator, we illustrate customer-specific solutions in the overall context of design, material and process technologies," adds Hahn.

Forward-looking statements This news release may contain forward-looking statements based on current assumptions and forecasts made by Covestro AG. Various known and unknown risks, uncertainties and other factors could lead to material differences between the actual future results, financial situation, development or performance of the company and the estimates given here. These factors include those discussed in Covestro’s public reports which are available at www.covestro.com. The company assumes no liability whatsoever to update these forward-looking statements or to conform them to future events or developments.
A polycarbonate (PC) compound from the new Makrolon® RE product range and PC films from the Makrofol® range are used in the manufacture of the demonstrator. Makrolon® RE and Makrofol® DE MB are polycarbonates and polycarbonate films, respectively, with a very low carbon footprint. They consist proportionately of raw materials derived from biowaste and residues, and are produced partly using renewable electricity. The sustainable origin of the raw materials is certified according to ISCC Plus (International Sustainability and Carbon Certification) and mass balanced.
The demonstrator is manufactured using a combined Film Insert Molding (FIM) and InMold Decoration (IMD) process, for which Sumitomo (SHI) Demag has developed a customized plant technology. The injection molding and back molding of the decorative foils can be combined in a single process step. As a result, production can be carried out not only in short, economical cycle times, but above all in an energy-efficient manner.
In the combined process, Makrolon® RE and Makrofol® allow for great freedom in the design of the wallbox, which is equipped, among other things, with an integrated display with touch functions. For example, seamless, large-area and glass-like surfaces in various colors can be implemented using just one tool. The capacitive and backlightable touch sensors from KURZ subsidiary PolyIC can be easily integrated behind the wallbox surface made of polycarbonate. With them, for example, the charging of the battery can be controlled steplessly by touching the control panel with a finger. In addition, the PC materials are well suited for the PMD (Print Mold Design) technology, which KURZ subsidiary Burg Design has optimized for the application of logos, for example.
At K 2022, Sumitomo (SHI) Demag will produce the demonstrator live via IMD technology at its own booth D22 in Hall 15. The new wallbox concept is also a key topic for KURZ at its booth A19 in Hall 5. The focus is on the numerous design options that arise from the use of a wide variety of decorative technologies. Visitors can also use an augmented reality (AR) app to design the demonstrator themselves and thus get a closer look at the technologies. Covestro will also exhibit the demonstrator and AR app at its booth A75 (Hall 6) along with material and component solutions for IoT applications, electromobility and electrification. In addition, the innovative wallbox concept will be the subject of a joint presentation at the booth of Covestro on October 20th, 2022, at 11 am.
