Dosing Cell 3E

The entry-level model for standard applications

The new Dosing Cell 3E is a 2-component low-pressure, mixing and dosing system for use in semi-automatic operation for gasketing, gluing and potting of a wide variety of components. With this system liquid, medium to high viscose media, such as polyurethanes or other reactive polymer materials can be processed precisely.

Sonderhoff has designed the Dosing Cell 3E to allow you as operator to easily and safely execute a wide variety of tasks. Standard operation is facilitated by the easy-to-handle, multi-functional MOBILE PANEL with integrated 6.5" touchscreen – an essential simplification for contour programming of components. The pre-adjustability and regulation of all system and process parameters ensure consistent production processing.

Economic

Build up and go!

With the 3E you can get started immediately. Place, plug & work!

To achieve this, we concentrated on the most essential characteristics and have designed the system for the most frequently used application characteristics. This has created a system which, through a very attractive entry-level price, enables extremely short amortisation times, and which produces small and medium quantities economically.

Efficient

The 3E saves time, space and costs

Everything in the machine is targeted at efficiency. The application rate of the MK 425 mixing head is between 0.5 g and 5.0 g per second, depending on material and mixing ratio. Experience has shown that this is the bandwidth which covers 80% of the current applications. The pressure tanks, with a 44 litre capacity for the A-component and 24 litre capacity for the B-component, accommodate the typical, asymmetric mixing ratio.

The machine concept itself is designed so that the machine can be delivered completely assembled in one piece in a container. Moreover the machine is prepared in such a way that it just needs to be set up at the destination location and connected to the mains supply. As soon as water and compressed air are connected, and the material is prepared in the material pressure tanks, production can begin – place, plug & work!

The machine is CE-compliant, and so an immediate, safe production start is possible. The manual liftdoor safely delimits the danger zone, so that additional protective fences or light barriers are not needed – an additional, efficiency-increasing saving of space and costs. Moreover, due to the high degree of standardisation, delivery time is shortened. Customers who are already familiar with the FIP(F)G technology can set-up the system on their own. Of course we would be pleased to support you on request!

Ecologic

Achieve a lot with minimal effort

The ecological high-pressure water rinsing system is the essential characteristic of environmentallyfriendly processing of 2-components reaction materials. The use of solvents to clean the mixing head becomes superfluous. With this proven technology you make an active contribution to environmental protection – throughout the machine's service life.

The Dosing Cell 3E – a genuine Sonderhoff

The Dosing Cell 3E can't do everything – but with comparably little effort, it can do a great deal! And it can continue to do so for many years, thanks to the proven Sonderhoff quality. In spite of all the cost efficiency: The 3E® mixing and dosing system uses the proven Sonderhoff components for all essential parts. Starting from the MK 425 mixing head, the central IPC controller, the modern sensors and actuators, to the pressure-controlled recirculation-valve technology, including automatic air nucleation, and extending to the high-pressure water rinsing system.
