An addition to ViscoTec’s preeflow® portfolio—eco-FEED—reportedly simplifies the emptying of double-chamber cartridges. The fully automatic pneumatic cartridge emptying system takes over the squeezing function to provide steady emptying while achieving precise material supply to the eco-DUO dispenser in a process-safe manner. eco-FEED is a stand-alone squeezing device for two-component, side-by-side double-chamber cartridges with separate control of the respective material chambers. The system can be operated as a desktop or integrated version.

The eco-FEED performs particularly well in applications such as electronics manufacturing where automation and process monitoring are required. Two-component epoxy adhesives, methacrylates, and polyurethanes are supplied by well-known material manufacturers in double-chamber cartridges. The specially developed cartridge adapters for eco-FEED reportedly ensure separation of the dispensing material. Both components are fed to the eco-DUO dispenser, which is responsible for precision mixing and application.

The single cylinders of the eco-FEED can be moved individually, enabling the separate pressurization of both components. As a result, the dispensing pressures can be matched and adjusted to suit the material to be dispensed—different on both sides and each with up to 6 bar.

The slim design of the eco-FEED allows it to be positioned in or on dispensing cells. In combination with the optionally available pedestal, the cartridge emptying system can also be positioned next to the respective dispensing system. With the integrated optical level monitoring on the front of the eco-FEED, the level is always visible. Electrical level monitoring is also available for maximum process reliability and automated monitoring of the dispensing process.

Additional features, such as a vent directly located at the cartridge adapter and a constant material inlet pressure, enable easy handling. Air bubbles are eliminated during material changes, and there is no interruption due to material break-off.

The eco-FEED is suitable for the most common double-chamber cartridges sizes (200, 400, and 490 ml). Dispensing is possible with mixing ratios from 1:1 to 2:1 and from 4:1 to 10:1. On request, the system can be adapted to fit other cartridge sizes.
