About us

Proton stands for positive change. With smart industrial solutions, we create meaningful jobs and economise on the earth’s resources. Together, we can contribute to a better world for the next generation.

We are better together.

Proton is a Swedish, family-owned industrial group in growth. We make long-term investments in people, companies and industries with potential to develop. Independent individuals united by a strong conviction: that real success is created through co-operation. The journey towards the goal, the challenges we face along the way and the pride in the work we do together are our common driving force. ENJOY SUCCEEDING TOGETHER®!

When you see the width of our business areas, you realise that Proton Group is not like any other group. Because how do you actually manage to stay focused in areas as diverse as surface treatment, lighting, pipe bending, pipe installations, machine safety and corrosion testing? The answer lies in power, commitment and a strong passion. A commitment that runs like a red thread through the group, which despite its size is familiar with short decision-making paths and proximity between owners, board and employees.

Based in the Värnamo area, Proton Group has been characterised by drive and initiative since its inception. Companies have been acquired or sold, operations have been added and also discontinued. What remains is a profitable and strong group that today consists of the brands Proton Engineering, Proton Finishing, Exaktor, Exlite, Cotec Labs, Cedoc, JL Safety and Weldin Gothenburg.

Proton Group’s founder, Leif Malveholm, had strong local roots and a clear desire to develop the Proton Group in the places where it operates. This is a legacy that his children want to pass on and that CEO David Gustafsson has become part of. Proton continues to engage with local organisations, businesses and the public sector to develop the regions where we operate. Taking our share of responsibility is important to us – it makes a positive contribution to our businesses.

Positive difference is about daring to do something different, challenging the established and striving for new, favourable outcomes.

The story of Proton Group

Making a positive difference was the basic idea behind the creation of Proton Group almost 35 years ago. Proton Group was formed in 1990 when a number of stakeholders, including Leif Malveholm, bought out a group of around ten industrial companies from the stock exchange. The intention was to build an industrial group that stood on several legs. At the time, the existing base was the surface treatment companies that are now part of the Proton Finishing business. The strategy was to invest in environmental improvement measures, as it was anticipated that stricter environmental regulations would make it more difficult for the smaller companies in the industry to compete. As part of the strategy, there was also the opportunity to create synergies between the surface treatment business and the construction business, which is now Proton Engineering. Throughout its history, Proton Group has faced both opportunities and setbacks, but has always managed to offer its customers and employees stability. After a series of heavy investments, including in the environment, as well as divestments of non-strategic assets, Proton Group is equipped for future growth.
