Effective for following spring characteristics to displacement of load! It suppresses variations in changes of spring characteristics.
At Sumihatsu Co., Ltd., we handle "non-linear characteristic springs." We perform taper processing of materials using NC lathes to achieve high precision dimensions. Furthermore, we shape them with NC coiling machines and conduct constrained heat treatment (press tempering) to minimize variations in spring characteristic changes. Please utilize this when you want the spring characteristics to follow the displacement of the load. 【Features】 ■ Achieves high precision dimensions ■ As load is applied to the spring, the effective number of coils that act as a spring changes, resulting in non-linear characteristics. *For more details, please refer to the PDF materials or feel free to contact us.

basic information
【Structure】 1. Unequal pitch coils can be formed without changing the wire diameter, which helps to reduce processing costs, but on the other hand, the height of the spring (free height) increases. 2. Conversely, tapered coils allow for a compact shape, but they require taper processing of the material, making them more expensive. *For more details, please refer to the PDF document or feel free to contact us.
