Festo has provided pneumatic control modules to ViscoTec for its high-precision two-component-adhesive dosing system. 

“In our new double cylinder devices, we rely on a Festo control module with pneumatic automation technology,” said Martin Stadler, managing director of ViscoTec, in a news release. “The control module indicates pressure and controls delivery. It was developed in close cooperation with Festo, from the development of the prototype to the current production-ready device.”

Double-chamber cartridges have the advantage of making it possible to work with media like adhesives, pastes, or silicones with two components of different viscosities. Many adhesive processes depend on these adhesive components being mixed in a precise ratio. The two applicator cylinders are moved independently of each other in this process, and the correct adhesive mixture is applied to the components to be glued, according to the press release.

The control module is a ready-to-install device delivered by Festo directly to the ViscoTec assembly line. The control module monitors the pressure and quality of the adhesive application independently of temperature and viscosity. Enabling volumetric filling, the module offers optical filling level monitoring as a standard feature. Customers have the option of an electric level monitoring version.

The double cylinder control module consists of a Festo VUWS valve, VHER hand lever valves, flanged pressure gauges, LR-D pressure regulators, fittings, silencers, and PUN tubing. “Having the module delivered ready for installation saves us time and effort, since we know we can integrate it directly into the cartridge applicator device without any adjustment issues. We could not do this without Festo world renown quality,” said Christian Heidinger, head of product management at ViscoTec, in the release.
