Company history
Foundation of HSM
The mechanical engineering company HSM Präzisionsteile & Sicherheitssysteme GmbH was founded in 1991 by Hans Sauermann in Ernsgaden near Ingolstadt. With 100 employees and an annual turnover of 16 million euros, it is one of the most stable and innovative medium-sized companies in Bavaria.
Change of name
On January 13, 2020, the mechanical engineering company HSM Hans Sauermann GmbH & Co. KG operated under the new name HSM GmbH & Co. KG. This renaming reflects the deeper integration as a subsidiary of Ringmetall AG.
Managing Director Kai Neubauer commented: “In 2020, we want to further strengthen our market position as HSM and expand it with innovative offerings for our customers. Despite economic challenges, we are striving for growth and long-term technological excellence while maintaining our economic independence.
The integration into Ringmetall AG and its group of companies offers additional synergy effects that will further strengthen our position.”
All known contact persons as well as the general terms and conditions of sale and delivery remain unchanged. HSM’s place of business will also remain the same: Im Gewerbegebiet 8, 85119 Ernsgaden.
