Spring design is vital for precision, durability and reliability in the renewables industry. We want our energy manufacture customers to know that their spring design delivers a solution that is trusted, securing optimised energy production applications.
We have been a specialist renewables industry spring supplier for decades, securing the best minds, materials and state-of-the-art manufacturing processes to deliver to evolving renewable applications as advancements within the industry and sustainability develop.
Maximising the potential of a spring by delivering exceptional design, development and manufacturing production processes is a key part of the performance success of our springs. Our audited, tested, recognised and reliable multi-stage manufacturing process guarantees the competitiveness and quality of your product.
Our state-of-the-art spring manufacturing technology, across the very latest and widest range of large-scale CNC spring coiling machines, coupled with the most advanced spring manufacturing processes and expert engineers, provides the highest quality precision springs.
The most distinguishing property of a coil spring's material is its mechanical strength and elasticity. The four key components when considering material choice are chemical composition, surface property, tensile strength and size. These essential elements build the structure from which our engineers bespoke design springs, to meet the demands of the application of springs within the renewable sector and to optimise the purpose and power.
We are dedicated to delivering engineering excellence with a quality personal service and want to ensure that your journey from enquiry through to coil spring manufacture to dispatch is simple, seamless and excels at securing the spring solution you require.
With a 170-year manufacturing legacy and state-of-the-art production and commercial infrastructure, we deliver a competitive environment dedicated to quality, accuracy and customer satisfaction, guaranteeing Lesjöfors Heavy Springs as the premium partner for your heavy-duty spring solutions.
All our customers have dedicated account managers that oversee every step of the commercial and production process. Our team become an extension of your team, proactively positioned to understand and secure your requirements, to fast-track any urgent projects and to listen to your business needs.
We have been spring manufacturing for over 170 years and energy provision and power generation over these many decades has evolved exponentially. As the renewable industry has developed, as have we, advancing our design and manufacture with the renewable companies we partner with, both responding to the industry as energy consumption and climate demands.
We work with a number of leading valve and actuator manufacturers, controlling mechanical movement and the flow of fluids across the world. Our springs adjust turbine blades and control gates in hydropower systems and are used in onshore and offshore wind turbine blade systems.
You will also find springs in generator control systems, in pressure relief and power transmission systems and across a wealth of damping and vibration control systems, absorbing shock and enhancing energy efficient operations.
Across wind and wave energy, from renewable energy storage to electricity production, springs are an essential part of energy technologies and energy sources.
The unique demands on a compression spring, tension spring or torsion spring as a consequence of the load and force requirements and temperature, fatigue and pressure resistance needed by the renewable industry require specialist knowledge and manufacture. As a leading renewable industry spring manufacturer, we have years of R&D and experience harnessing the power of spring design to deliver the exact engineering required to optimise power generation applications. All our projects start with consultations; establishing drawings to meet precise specifications and designing prototypes that evolve as the product design process evolves. Performance handling assessments, technical reviews, safety testing and failure analyses collaborate to direct the demands of the precision spring and secure the right custom springs for the right power generation application performance. Manufacturing and consistently testing samples before full production runs, is all part of the product service and customer culture we believe in to achieve product optimisation for our customers.
With our first class engineering and quality teams, technologies, manufacturing processes and advanced CNC spring coiling machines, we deliver an exceptional bespoke spring design and manufacturing service for the renewable sector. Continual investment in our facilities and services keeps us at the leading edge of precision spring manufacturing, allowing us to guarantee the maximum potential out of our springs through our expertise and technical analysis on the extreme stress boundaries of material capability and spring design.
We’re leaders in our field because we manufacture from the highest quality wire and feature the most advanced coiling and cutting technology. This results in us excelling at spring manufacturing standards within the renewable industry, delivering spring solutions that deliver the right product for the right application and guaranteeing uniformity and precision from the first spring to the last.
An essential part of the manufacturing process, heat treatment removes residual stress introduced to the material during the coiling process. The treatment stabilises the springs dimensions for greater accuracy and increased fatigue life and our oven facilities use forced convection technology to ensure the material is uniformly heat treated from surface to core. Our larger renewable sector spring designs, using a wider wire diameter, require a hot winding process as the extreme heat allows large scale wire diameters to be coiled.
The process of heating up wire to approximately 900 degrees Celsius, quenching in oil and tempered to complete the heat treatment, allows the spring material to be coiled to the specifications required.
Our quality management systems conform to ISO 9001, 14001 and 45001 and our teams are experts in their field. Our global network of quality engineers ensure the spring products meet the quality standards required by the design and are the one stop shop for quality control and spring manufacturing standards within the renewable sector.
The renewable industry is constantly evolving, changing with the needs and demands of consumption and climate impact. We’re aiding the innovation of new future power generation activity as we advance our materials, technologies and our sustainable knowledge.
Ongoing awareness of our entire value chain’s climate impact has increasingly identified our material impact on scope 3 emissions (scope 3 emissions are associated with the use of raw materials, mainly metals in component manufacturing) and demonstrates the value of climate focused collaborative partnerships.
We are working closely with our customers to offer energy-efficient solutions through optimised design and low carbon material choices.
We’ve got a lot of work yet to do and partnerships are key to the successful implementation of our comprehensive sustainability programme which will innovate the future of renewable industry spring suppliers.
Our groups ambition is to be the most sustainable spring solution supplier.
Limitations come down to the application requirements of the spring, material choice and tolerances. Our engineers are the best at optimising the potential out of spring designs.
