Every breakthrough battery starts with the right tools, and Nogamigiken has become the precision tool manufacturer that makes such innovation possible. Since its founding in 1970, the company has refined machining and measurement technologies under its guiding principle of Management of Technology, using core expertise to deliver solutions that create lasting value. “We carefully listen to both explicit and latent customer needs to propose optimal products and services,” says Ryota Nogami, representative director. This customer-focused approach ensures that Nogamigiken drives enduring client relationships while advancing battery development. Its portfolio spans ultra-sharp cutting blades, precision gauges, long-life dies, and specialized punching systems designed to meet the demanding requirements of secondary battery development. These tools feature innovations such as adhesion-resistant cutting for aluminum-based cathodes, ultra-narrow clearances down to two μm, and selectable clearance options that help minimize burrs and delamination. Unlike others that cause the active layer to collapse or peel, Nogamigiken’s handheld punches prevent damage, preserving sample integrity for accurate mass and density measurements. By combining deep technical mastery with a commitment to customer-driven innovation, Nogamigiken has become a trusted partner to automotive leaders, battery producers, universities, and research institutions across Japan, Europe, and North America. Innovative Tools for Next-Generation Batteries Since the 1990s, Nogamigiken has expanded into press die design and mass production, creating ultra-precise, long-life components. In 2000, it launched a dedicated solutions business to address explicit and latent customer needs, providing tailored products and technical support. By 2008, the company had entered the battery development field, helping manufacturers and researchers tackle the challenges of processing delicate electrode materials.
