About Snel AG, Zweigniederlassung Kerzers
Founded in 1903, Herrli AG has operated since an intra-group merger in 2019 as Snel AG, Zweigniederlassung Kerzers (Kerzers branch), and has been part of the Neumo-Ehrenberg Group since 1969. The company offers stainless steel tubes and valves as well as components and assemblies made of stainless steel and special alloys for fluid technology. Its core competence lies in manufacturing custom products in small and medium series: punching, bending, notching, pressing and deep drawing on eccentric and deep-drawing presses (6–160 t), CNC milling and CNC turning, computer-controlled orbital welding including parameter documentation, as well as argon and spot welding, soldering, grinding, polishing, tumble finishing and degreasing. Materials include stainless steels such as 1.4307, 1.4404, 1.4435-BN2, 1.4539 and Hastelloy C-22, supplemented by brass, copper and aluminium. The products are used in the pharmaceutical industry, biotechnology, chemicals, the semiconductor and solar industries, food technology/dairies and medical technology. In addition to production in Kerzers, the site also performs a sales function; delivery is international EXW Kerzers from the database-delivery.
