At Tokuhatsu Sankyo Seisakusho, we specialize in the processing of cup washers and bent washers.
We can also manufacture cup washers that require load. The available plate thickness ranges from approximately 0.05 mm to 1.0 mm, and please feel free to inquire about sizes! We can accommodate prototypes starting from one piece. Materials like stainless steel are said to have springback, making bending difficult. Our company utilizes years of know-how to take on challenges with thin and small products!
Inquire About This Product
basic information
Cup washers and bent washers are created by bending a thin circular plate, which generates deflection and load. There are similar products such as wave washers, which are also one of our specialties. If you are considering the use of cup washers, bent washers, or wave washers, please feel free to contact us!

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. Available materials: Stainless steel (SUS301, SUS304) / Special steel (SK85, SAE1060) / Phosphor bronze (C5210) / Beryllium copper (C1720) and others upon consultation. ISO certification obtained: ISO14001:2015, certification renewed in November 2017 ISO9001:2015, certification renewed in December 2017.
