We will bring to life the request of a specialist in thin plate springs: 'Can you make a spring like this?'
In-house integrated production from prototype to mold to mass production! The thin springs from Tokuhatsu Sankyo are custom-made exclusively for your company. We will meet any request you may have.
At our company, we not only handle prototypes and mass-produced items but also seek new possibilities for thin plate springs, turning our customers' requests of "Can you make this type of plate spring?" into reality. We manufacture high-efficiency, high-precision, low-cost thin plate springs from a minimum thickness of 0.05mm using "multi-forming" and "progressive stamping." Through detailed discussions with our customers about usage methods, we capture the deeper aspects of their needs and provide shape proposals. For wave washers and disc springs, we can also perform load calculations and suggest designs. We can accommodate prototypes starting from just one piece. Mass production without molds is also possible. 【Main Products】 ■ Manufacturing of metal plate springs - Plate springs - Disc springs - Wave washers - Mold production - Prototype development 【Materials】 - Stainless steel (SUS301, SUS304), etc. - Special steel (SK85, S60C), etc. - Hardened steel (Bainite steel, ribbon steel), etc. - Copper (phosphor bronze, beryllium copper), etc. *For more details, please refer to the PDF materials or 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.
