Powerful compression springs for the heaviest needs
As one of few manufacturers in Europe, Lesjöfors specializes in the manufacture of compression springs for extremely heavy loads. Not unusual are springs in the wire dimension of 65 mm weighing up to 350 kg.
There are only a few manufacturers in Europe with the right skills and capacity for the heaviest spring segment. Lesjöfors has for many years produced heavy springs to customers in areas such as railway, automotive, paper, mining and military industries. These springs must withstand extreme conditions and require wire dimensions up to 65 mm weighing up to 350 kg. Lesjöfors manufactures both compression springs, tension springs andtorsion springs in large dimensions. Many of the largest springs are manufactured in Åminnefors, Finland and in Lesjöfors, Sweden. The spring production comprises everything from fully automated processes to hand made bespoke springs.
Materials for extreme environments
In some cases, the spring must withstand great strains in terms of high or low temperatures, exposure to chemicals or mechanical abrasion. High-performance materials are then often required, so-called Super Alloys. Lesjöfors has extensive experience working with these materials and stocks many of them such as Inconel X750, Inconel 718, Nimonic 90, Monel K500 and MP35.
Advanced calculations and tests
To ensure that the spring keeps its promises, Lesjöfors provides advanced test and measurement equipment for e.g. FEM analysis, fatigue and relaxation tests. The choices made in the beginning of a project are essential for the final product´s quality and cost.
“Our experienced spring support team is happy to help with advice about materials, finish treatment, calculations and technical support, among other things. Please contact us as early as possible in your project so we can work out the optimal conditions right from the start, says Mats Blåder, MD of Lesjöfors Fjädrar.
Fast deliveries
A delivery from Lesjöfors is always characterized by high reliability of supply at the agreed time. For urgent matters with products in standard materials in the dimension 8-26 mm there are also opportunities for express delivery.
“Do not hesitate to contact us about your specific requirements. We are happy to tell you all about the opportunities we can provide for an optimal spring project as cost-effectively produced as possible, says Mats Blåder.
