In 1994 we merged with Mechanik AG and relocated to our present company domicile in Haag in the Canton of St. Gallen (Switzerland). This was also the starting point for the industrial production of our membrane bellows. In 1996 we were the first company worldwide to succeed in putting a fully-automated bellows welding robot into operation. Just one year later in 1997 we were able to start up our production of titan bellows for serum pumps in medicinal technology. In 2002 we put our first laser welding robot into operation. Our attention is still focussed on permanently advancing the development of automation in order to be able to offer perfect quality solutions at an attractive price. COMVAT membrane bellows are exemplary in terms of functionality and suitability for a variety of applications.
