We combine different materials through our unique processing equipment such as press machines and laminating machines, along with our expertise in process design, and high-precision punching and bonding technologies.
Non-contact power transmission is a technology that allows wireless power delivery to batteries (secondary batteries) without using connectors or cables. It has been put into practical use in smartphones and wearable devices. Non-contact power transmission commonly employs electromagnetic induction and electromagnetic resonance methods, with the main components being: - Coils (which convert electromagnetic waves into current) - Shielding materials (for electromagnetic wave shielding) - Rectifier circuits (which convert alternating current to direct current) At Otis, we contribute to the high performance of electronic devices by combining functional materials such as films, metal foils, and foams with adhesive tapes. Through our unique processing equipment and process design technology, we can punch out and bond different materials, processing multiple components in a single line and integrating them. Regarding the components for non-contact power transmission, we have achievements in: - High-precision punching of 0.1mm thick copper foil - Punching and bonding of hard and brittle materials like graphite sheets - Know-how to minimize burrs and cracks during punching Based on these achievements, we contribute to reducing the number of parts and processes through the processing and integration of coils and shielding materials. We also have numerous accomplishments in mass-producing projects that other companies have declined. Please feel free to contact us.
