Specialized Sanko Manufacturing's one-of-a-kind technology: Wave Washer
■Wave Washer Wave washers and disc springs achieve compact space while exhibiting the same spring force capabilities as coil springs. They are often used to suppress "wobble" with moderate rebound force, act as cushions, or secure components. With our unique technology that cannot be replicated by other companies, we solve your problems. ■Our strength lies in technology that cannot be replicated by others, solving your problems. Depending on the application, we propose appropriate materials and designs, and carry out everything from mold creation to production, delivery, and maintenance in a consistent manner. Additionally, while main contractors typically place orders for the same spring products with two subcontractors for insurance purposes, we also manufacture items that cannot be ordered from two companies. Our products are included in components for the world's largest mobile manufacturers and car audio systems exported to North America. "Our technology cannot be replicated by others," which is our significant strength.

basic information
A wave washer widely used as a spacer spring. It is made of a thin annular plate with waves and is widely utilized as a spacer spring. It effectively averages axial loads (thrust loads) around the circumference in response to static loads or small movements, making it useful for cushioning in tight spaces. It consists of thin washers made of spring steel that are bent into multiple wave shapes, and its applications include preventing loosening of screws, eliminating play between components, and serving as a spacer spring to secure space along the same axis in a spring-like manner.

Company information
We will bring to life the idea of 'Can you make a spring like this?' 'Thin plate springs' are not often visible in everyday life, but they are incorporated into various products, playing a crucial role as 'precision components' from within. 'Cars,' 'computers,' 'DVD players,' 'water heaters,' and many other precision machines do not exclude the use of 'thin plate springs.' At Tokuhatsu Sankyo Seisakusho, we shape our customers' ideas of 'Can you make a spring like this?' in pursuit of new possibilities for thin plate springs, including prototypes and mass-produced items. We manufacture thin plate springs with improved work efficiency, high precision, and low cost through 'multi-forming' and 'progressive press' techniques, starting from a minimum thickness of 0.05mm. Wave washers and disc springs can have load calculations performed in-house. Please feel free to inquire.
