International SPRING MAKERS CONFERENCE, June 22nd 2022

On June, 22nd 2022, the International Spring Makers Conference of the ESF took place at the wire fair in Düsseldorf. Mr Paul-Bernd Vogtland, President of the European Spring Federation (ESF), welcomed more than 90 international guests to the event. The joy of meeting in person again after more than 2 years of COVID Pandemic was clearly appreciable. Afterwards, the General Secretary of the ESF, Dr. Michael Hagedorn, informed about the worldwide standardization activities in the field of technical springs.
Key Note Speaker Dr. Michael Thiele, ArcelorMittal Hamburg GmbH, gave insights into the challenges of the steel industry with carbon neutral steel.
At the concluding COME TOGETHER, there was a lively exchange between the participants in a relaxed atmosphere.

10th International Congress of Spring Industry in Hamburg

From September 26th to 28th 2019, the international spring industry as well as representatives of the supplier industry met at a conference in Hamburg. This was arranged by the “European Spring Federation (ESF)” and organised by the association of the German spring industry (VDFI). The 160 participants came from 24 countries from around the globe. 15 exhibitors used the opportunity to enter into a discussion with participants. Tomi Parmasuo, President of the ESF, moderated a tight program of more than 20 talks. As the key speaker, Tomas Hedenborg, President of Orgalim, spoke about EU industry politics 2030. Challenges are global geopolitical and economic developments, such as, for example, global power shifts – China will be the largest economic power in the world by 2050 – and poor trade and low investments because of protectionism. Further challenges are economic and technological development – when it comes to artificial intelligence (AI), the EU is strongly behind – and social and societal developments such as, for example, an aging society – in the year 2030 Europe will be the oldest region of the world – and the lack of qualified employees. Last but not least, naturally also climate and environmental threats belong among the greatest challenges. Goals would be foreseeable here, as well as stable legal framework conditions, in order to lead the European industry to a climate-neutral economy by 2050.

Following this were short talks from the countries of China, the Czech Republic and Slovakia, France, Germany, India, Italy, Japan, from the northern European countries of Denmark, Finland and Sweden, from Poland, South Korea, Spain, Switzerland, Turkey, the UK and the USA on their respective economic situation in the spring industry.

In the afternoon Shigeo Aiba, President of Togo Seisakusyo Corp., reported on the international standardisation activities of the ISO / TC 227 “Springs”. Prof. Dr. Ulf Kletzin, Technical University Ilmenau, presented for the VDFI research projects that have been implemented on the topic of creep and relaxation behaviour of spring steel wires in coil springs. Dr. Uwe-Peter Weigmann, WAFIOS AG, reported on the industry 4.0 uses in the wire and spring industry. Pablo Capellán presented the metal additive manufacture (3D printing) of optimus3D. Alexander Busse, research association on automotive engineering, presented on the topics “E-mobility – Quo vadis? Perspectives of future drive systems”. The talks are ready to download on the homepage of the ESF. The joint dinner in the building of the town hall, a part of the Hanseatic tradition in the inner city of Hamburg, presented the opportunity to exchange ideas. The conference ended successfully and with a good mood on Saturday after a harbour tour and lunch in the Elbe Philharmonic Hall. The next international conference of the spring industry will take place from October 7th to 9th in 2021 in Barcelona/Spain

The Economic Situation in the German Electrical and Electronic Industry

Report of ISO/TC 227 Springs

The economic situation of the spring industry in different parts of the world:









The European Spring Federation invites to the International Spring Makers Conference and to the Come-Together-Dinner. The aim of this year is to exchange experiences among the spring manufacturers. The trade fair wire in Düsseldorf reprsents an ideal occasion for this. We will have a whole series of interesting presentations on the economic situation of the spring industry in Europe an around the world on the programme.

In the evening the ESF invites you to the Come-Together-Dinner in the Restaurant “Schnellenburg”, directly across the trade fair grounds. Here you can make new contacts and foster existing ones in a relaxed atmosphere.

We are looking forward to welcome you in Düsseldorf.

Here you can find the invitation and participation form.
