Wave springs can be the perfect solution when spring space is limited. A wave spring provides the same effect as a spiral or compression spring but with half of the spring height. Now Lesjöfors Group has invested in developing the concept.
Wave springs have been on the market for quite some time. The spring product has the same force as a spiral or compression springs, but only need half the spring height. This provides greater flexibility in the project and the option for smaller and more compact spring areas. One example of usage is in mechanical seals.
In 2016, the Lesjöfors company Stece Fjädrar launched a large investment plan to further develop the technical capacity and expertise in wave springs to meet the increased customer demand. “Together with our sister company Lesjöfors A/S in Tinglev, Denmark, we’ve started a project with a German company who manufactures hydraulic motors,” says Michael Arvidsson, MD at Stece Fjädrar.
Thanks to an increased demand from customers, and belief in the huge potential that wave springs can provide customer projects, the decision was made to invest in a new WAFIOS SNA 22 machine. The new equipment extends dimension variations from the current minimum of 47mm down to 20mm diameter, which matches many requests. The new machine was scheduled to be operational the end of September 2017, which means wave springs from 20mm to 250mm can be manufactured.
