Decorative panels for EV and electric vehicle interiors! Lightweight and integrated molding for radio wave transmission.
Three elements to differentiate the interior of EVs in one part: simultaneous realization of decoration, weight reduction, and radio wave transmission.
In the interiors of electric vehicles such as EVs, PHVs, and FCVs, there is a demand for parts that simultaneously meet the requirements of a metallic design, radio wave permeability, lightweight interior components, and a luxurious surface design. Using Yoshida Technoworks' discontinuous vapor deposition film in in-mold forming technology, it is possible to mold decorative panels that have a metallic luster while allowing radio waves to pass through. Furthermore, the double in-mold method enables the integrated molding of a metallic decorative layer and a protective coat layer, eliminating the need for subsequent painting or coating processes. The molding based on lightweight PC resin is expected to achieve significant weight reduction compared to existing metal components.
