New machinery simplifies the production of complex strip components

Lesjöfors Stockholm Fjäder in Vällingby, Sweden, has recently invested in two new machines, a laser cutter and a deburring and edge treatment machine. The investments have brought significant capacity increase and quality improvements.

The new laser cutter from Amada doubles the capacity since the effect of the new laser is 4 KW compared to the previous 2 KW. In addition to the increase in capacity, the laser cutter can now handle thicker materials. This applies especially to Super Alloy materials for disc springs, tensioning washers and leaf springs. These are materials that must withstand extremely corrosive environments or very high temperatures.

More efficient handling of disc springs

Disc springs and tensioning washers in high-alloy materials are increasingly demanded from Lesjöfors Stockholm Fjäder. Thanks to the new deburring and edge treatment machine from Costa a more efficient surface treatment is achieved. It breaks the edges and surface-grinds materials in a very efficient manner and can reduce the time for subsequent tumbling by up to 90 percent.

“The new machine shortens our lead times and increases our capacity while improving the quality of our products. We have a huge demand, especially from our Norwegian sales company, of disc springs in high-alloy materials. I am pleased that we now can meet the market expectations in a better way”, says Mårten Glas, MD of Stockholm Lesjöfors Fjäder.

Spring development without tooling costs

Lesjöfors Stockholm Fjäder now has an efficient concept to develop prototypes and small and medium-sized series of strip components (stampings). The combination of modern laser technology, efficient edge and surface working machines, a unique range of universal tools and a solid material stock gives perfect conditions for manufacturing leaf springs and strip components in complex shapes without tooling costs.

“Challenge us with your request, we can most likely help you with your requirements in this area”, says Mårten Glas.
