From a mechanical workshop to a specialist in efficient workpiece clamping technology – the Swiss company GRESSEL AG has been involved in metalworking for 100 years.

1923 as a mechanical workshop

1933 first workbench vise

GRESSEL AG was founded in 1923 as a mechanical workshop. In 1933, the first workbench vise was created and started a success story. With the high-pressure tensioner launched in 1965, the company succeeded in gaining access to industrial production, and subsequently the medium-sized company repeatedly caused a sensation in the industry „in terms of tensioning technology“. Since mid-2014, GRESSEL AG has been part of SCHUNK GmbH & Co. KG from Lauffen / Neckar. SCHUNK is the competence leader for gripping systems and clamping technology. More than 3,500 employees in eight plants and 35 own national companies ensure an intensive market presence. With over 11,000 standard components, SCHUNK offers the world’s largest range of gripping systems and clamping technology from a single source.
