We are ready to take on any challenge!

From large springs to small springs, here we introduce our springs that never fail to live up to expectations.

Disc Springs

All types of custom-made disc spring! Leave it to us for space-saving designs

Features Of Our Springs

The disc spring is a spring washer with a conical shape. It can be subjected to large loads or impacts with minor deflection, and its characteristics can be changed by itself or by stacking. The disc spring is infamously tricky to design. It also has the extreme aspects that the relationship between deflection and load inverts and a slight dimensional deviation greatly affects the load characteristics. We will make the best possible proposals to you based on our unique design and manufacturing expertise.

Examples of Applications for Disc Springs

Tokai Spring offers custom-made disc springs according to your desired application and load characteristics. Not only can we make it to your desired size, but it is also possible to make a prototype with materials that are not in circulation and carry out verification tests. Disc springs are used in applications such as stabilizers that support nuclear pressure vessels and mounted parts for mechanical parts.

Key Points on Our Devotion to Handmade Springs

As there are no standard dimensions and each and every spring is handmade, you can freely select the shape you want. What’s more, because we can make each spring consistently, we can deliver highly accurate spring specifications that cannot be achieved by machine-dependent manufacturing.

  • We support design and production even for small lots of one or two springs
    In the spring industry, our “complete custom-made production & high-mix, low-volume manufacturing” is an extremely unique production system which has not changed since our founding.
    We guarantee to deliver the quantity you need, when you need it, at high quality.
  • We support all kinds of environments with the likes of heat resistance, corrosion resistance, and durability
    Springs are very sensitive to high and low temperatures and corrosive atmospheres such as rust. Tokai Spring conducts daily verification tests to properly maintain the performance of our springs in any environment such as at temperatures of 100°C or higher, -20°C or lower, as well as for applications in which our springs are exposed to seawater or industrial water!
