The privilege of flexibility

Corekits and materials

Core material kits consist of up to 1600 unique items used to increase the durability and performance of wind blades. By combining the right thickness and sizes and cutting them into the right shapes, a kit becomes a lightweight yet sturdy component to support the wind turbine blade. A kit usually consists of shells for the lower and upper part of the blade and a vertical web in the middle for extra support.

Our kits are made from your choice of PET foam or balsa wood. Both are materials with a high stiffness-to-weight ratio, but while balsa is a natural wood grown in Ecuador, PET is a foam made of recycled plastic all around the world.

Quality and sustainability

Our passion for sustainability stems from decades in the renewable energy sector. Whether it be optimising the material yield or reducing waste, our engineers continuously work on solutions that, not only reduce production costs but also reduce our carbon footprint. We are also conscious to keep energy consumption in mind when buying new equipment for our production facilities. If the market does not provide us with the standards we require, we develop proprietary machinery designed to reduce waste and dust.

What we do and how we do it is a direct consequence of a constant and conscious attention to quality. We understand that wind turbine manufacturers operate in an industry with very little room for error, and so, all aspects of our processes are calibrated to the finest detail. Our global sites all hold ISO Quality Management System certificates.

Our process

Striving for the perfect fit

We strive to reduce strain on blade manufacturers from initial design, prototyping and our in-house production to final delivery and ongoing support. Our production setup is flexble and allows us following turbine OEMs as they are expanding.

Consulting and design

We work with any level of input to produce custom drawings that suit the blade model’s needs and requirements in our unique in-house engineering division.

Our technical designers strive for the perfect fit and adjust their designs based on their deep knowledge and experiences of working with the CNC machines themselves.

Throughout this process, we are passionate about finding the optimal choice of material in close collaboration with you. AutoCAD drawings illustrate the exact specifications for each piece of the kit. If the project calls for a more detailed design, 3D models are produced to visualise complicated parts.

Fitting as many core kits as needed until they perfectly suit the manufacture’s blade is our speciality.

From the initial drawing, we take the design to our production floor where a prototype is fabricated to test in your blade. To save time in blade production, our engineers are on-site when we fit each custom-made prototype into your mould.

We know that the right prototype requires multiple iterations, but it is a crucial step in the production process to avoid deviations that could lead to collapse during the operation of the turbine. The prototyping process is centralised at our headquarters in Ringkøbing, Denmark.

Innovation

At JSB we do things smarter and we push the industry to do the same. Starting with our own back yard, we believe in continuously optimising our processes.

As the only kitter with an independent on-site laboratory, we are able to test new ideas as we constantly improve our procedures so that you can get a better, more cost-effective product. The developers in the laboratory are solely dedicated to testing and optimising of new methods, and we take pride in investing in resources to spend appropriate time thinking outside the box.

We strive to find the most cost-efficient processes and materials, and by constantly scouting for new partnerships, we find solutions to drive down cost of producing wind energy together with clients and suppliers.
