GEMÜ Switzerland celebrates its 40th company anniversary on 23rd September 2021. The foundations were laid with three employees and one injection moulding machine in the canton of Zug in 1981. Two years later, in 1983, GEMÜ Switzerland moved to the Rotkreuz site which today forms the headquarters for the Swiss GEMÜ Vertriebs AG. There is an additional production site in Emmen (canton of Lucerne). GEMÜ Switzerland has been producing ultra-pure valves and accessories for semiconductor production here since 1988 and products for the pharmaceutical, biotech and medical industries since 2003. The year 2012 saw the completion of the new cleanroom plant, which has since become the service and competence centre for high-quality plastic solutions within the GEMÜ Group.
