You absolutely have to see this! Technical documentation.
Kyo-Wa Hearts specializes in "thin, small, and fine" micro and precision metal stamping, handling everything from prototypes to mass production using progressive dies. For 70 years since our founding, we have taken on the challenges of high-difficulty metal processing and have addressed various problems and issues that arise within that scope. Additionally, we utilize IoT to continuously improve our production sites, develop our own products, and engage in crowdfunding, among many other new initiatives. We are introducing the know-how gathered in this process as technical documentation. It's a must-see!
