    > About Us at Spring Expert  

The “Spring Expert” is Mark Hayes B.Sc., C.Eng., MIMMM. Mark has acquired a practical and academic knowledge of all aspects of spring technology by working with high strength materials since graduating in metallurgy at Leeds University in 1975.

Services offered include consultancies, training, problem solving and design. Wire and strip producers utilise the services to gain knowledge of the technical requirements of the spring material supply chain. Spring manufacturers use the services to optimise their production processes, to solve manufacturing and design problems and to commission failure investigations or interpretations thereof. Users of springs benefit from these services to optimise their designs, reduce costs, and improve the reliability of springs, which are used in almost all manufactured items from automotive, aerospace, rail, medical, mechanical, civil, electronic and electrical engineering, leisure products and practically all other industrial sectors. Almost everything that is made is better for having springs incorporated into their construction.

As retirement takes over from working, free lessons are now offered to school children within 80km of Sheffield. Everyone should know something about the springs we use every day of our lives, so book a lesson for your class today!


The last courses that Spring Expert delivered were in USA, China, Canada, Eastern Europe and Scandinavia. All these courses were very well received with entirely positive feedback. One delegate recorded in his feedback that he "learnt more than he expected". Another delegate recorded that he was not confident that his English would be good enough to understand everything, but the clear English and accompanying course manual meant that language issues were minimal. The next courses will be given in UK.

In November 2015 Spring Expert presented a paper about the effects of heat treating compression springs at an international spring conference in Tokyo.

Spring Expert attended Wire 2018 on April 16-17th . It was really good to meet many friends from the wire and spring industry at the show, The feature of the show was the ever-increasing number of Chinese exhibitors - a whole hall of them this time, but the astute of them were not in Hall 16, which had less visitors than any other. I may attend Wire 2020 in December.

On the Links page of this website, there are numerous articles and technical papers written by Spring Expert over the last 20 years. Several further papers were added in 2014,but as Mark gradually reduces his workload there will be few more.

Mark was employed by the Institute of Spring Technology (IST) for 28 years. He is committed to the technical goals and products of IST. During the eight years since he left he has gradually reduced his work commitments as an independent self-employed consultant/ trainer to the global spring industry, but he still works 1 - 2 days per week on average. He recently enrolled as a STEM embassador - that is a person who encourages youg people to study Science, Technology, Engineering and Mathematics in the UK.

“A spring is a device for storing energy and giving it back when required." Whether it is cold or hot formed, made from wire or strip, Spring Expert can help ensure the product is as light as possible, economical and utterly reliable. Compression springs are often more than 99% efficient, and spring expert can help you towards similar efficiency and reliability in extension, torsion, spiral, disc, leaf and all other types of spring.
