Company information
Technical skills backed by experience and proven results.
The powerful springs that were first standardized in Japan using non-circular cross-section materials have become the standard in Japan. Based on customer requests, we have standardized high deflection powerful springs and powerful spring α. The resin guide has been developed and standardized to maintain the original lifespan of the springs. Additionally, they are adopted in manufacturing machines and presses used worldwide, based on the international standard ISO 10243, such as ISO STANDARD. We offer sizes that match manufacturing machines used in various industries around the world, ensuring high strength and durability.
