創和 List of Products and Services

**Features of Sohwa** ■ Prototype Support for Research and Development We can design from scratch and manufacture original sheet-type coils based on your desired materials, shapes, and sizes. We have extensive experience in punching and laminating copper foil, tape, and insulating materials used in wireless power transmission coils. We can accommodate prototypes even without drawings, based on your ideas like "I want to make something like this" or from existing samples you have. ■ Production System According to Desired Lot Size Prototypes can be made from just one sheet processed item. Additionally, we can propose automated processing (roll processing) for future mass production. Depending on the shape, we can also discuss production methods that minimize initial costs without using molds. ■ Material Proposals Based on Expertise We handle copper foil (electrolytic copper foil / rolled copper foil) and can propose the most suitable materials from a wide range of options. When laminating copper foils, we can select conductive double-sided tape or use low-tack backing paper, leveraging our past knowledge for selection and proposals. If you are a customer looking to produce small lots for research and development or seeking a processing manufacturer to bring your ideas to life, please feel free to consult with us.
