royos joining solutions
GmbH

The company royos joinig solutions, formerly Stirline GmbH, with office in Graz, Austria, was founded in 2022 by Mario and Cornelia Leitner and is therefore a young player on the FSW market - but that only applies to the company! In fact, royos has knowledge from more than 15 years in the areas of automotive, design, prototyping, production of plastic injection molding and aluminum die-cast parts and several years of experience in the FSW for aluminium in industrial use and series production. We are mainly active in e-mobility, aviation and the energy sector. What distinguishes us from others? Our distinguishing feature is our many years of experience in the construction and component design of complex assemblies, the way of thinking geared towards production or FSW contract manufacturing and encounters at eye level - togetherness.
