Bekaert has been delivering some of the best spring wire on the market for decades, to a wide range of industries including construction, automotive, agriculture, energy and medical devices, to name just a few.
The key to our continued success comes down to two words: collaboration and innovation. Our close working relationships with both spring manufacturers, design and pharmaceutical companies has resulted in continuous innovation in the field of medical spring wire production.
Our steel-based medical spring wire product range has been designed for highly critical medical spring applications. Our products can deliver tight tolerances and higher spring ratings, increased accuracy and repeatability as well as increased fatigue-resistance and anti-corrosion properties – vital characteristics in drug delivery systems and dispensing applications.
We can provide you with the medical spring wire you need based on your rigorous specifications for both simple and complex design solutions from our off-the-shelf range or customize a solution to meet your specific requirements.
Key wire properties
We understand that your requirements can change and evolve over time, based on the nature of the applications where the spring wire is used and the changing standards and requirements that your product must fulfil to maintain its leading market position.
We pride ourselves on our ability to meet our customers’ needs. We approach our innovation and product development process from a strong foundation of four clear properties that define the characteristics of the medical spring wire we deliver to you:
What spring force is required by your medical device?
How long should it continue to perform?
Does it require increased corrosion resistance?
What are the design requirements you must meet?
Based on these varying parameters we can help you to find the best solution.
What are the design challenges of your medical device?
