3E Dosing Cell

The starter model for standard applications

The 3E dosing cell is a low-pressure mixing and dosing system for two components for semi-automatic and fully automatic application of sealing foams, adhesives and potting compounds to a wide range of parts. This machine precisely processes liquid, medium and high viscosity compounds such as polyurethanes or other polymeric reactive materials. A shuttle table is optionally available. It permits the single-level processing of parts on two support platforms.

3E dosing cell is designed in such a way that you as an operator can easily and safely execute the most varied tasks. It is operated via the easy-to-handle, multifunctional mobile panel MP 2 with integrated 10.1” (WXGA TFT) touch screen – a significant simplification for contour programming of components. The pre-adjustability and regulation of all system and process parameters ensure consistent production processing of the dosing cell.

Here you will learn, how easy it is to start and operate the 3E dosing cell – place, plug & work! The video also informs you about the functionality of the dosing cell, where the individual machine components are located at the system and how the optionally available shuttle table can be attached to the dosing cell in self-assembly.

3E Dosing Cell – the Economy Class: economic – efficient – ecological


Build up and go!

With the 3E dosing cell, you can get started immediately: set up, connect and produce – place, plug & work!

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


The 3E Dosing Cell saves time, space and costs

Everything about this machine is targeted at efficiency. Material viscosities from 200 to 100,000 mPas can be processed. Depending on the configuration, the output rate ranges from 0.5 to 5.0 g/s. Experience has shown that this is the bandwidth with which 80 % of current applications can be reproduced. In addition, the mixing head ensures an exactly dimensioned coupling range through the nozzle lock system STOP-DROP DVS 3. The material pressure tanks, with a capacity of 44 liters for the A-component and 24 liters for the B-component, accommodate the typical asymmetric mixing ratio, which can be infinitely adjusted from 10 : 1 to 1 : 2.

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

The machine is CE-compliant, and so an immediate, safe production start is possible. The manual lift door safely delimits the danger zone (traversing range of the linear robot), so that additional protective fences or light barriers are unnecessary – a further efficiency-increasing saving of space and costs. Moreover, due to the high degree of standardization, delivery time is shortened. Customers who are already familiar with the Formed-In-Place-Foam-Gasket (FIPFG) technology can start up the system on their own. Naturally, we will be happy to support you on request!


Achieve a lot with minimal effort

The ecological high-pressure water rinsing is the essential feature of environmentally responsible processing of two-component reactive materials. The use of solvents to clean the mixing head becomes unnecessary. With this proven technology customers make an active contribution to environmental protection – throughout the machine’s
service life!

The 3E Dosing Cell

The SONDERHOFF 3E dosing cell is not an all-rounder – but with comparatively little effort it can do a great deal!
Despite its cost efficiency, the 3E dosing cell uses the proven machine components for all essential parts, starting from the precision mixing head MK 825 BASIC, the central IPC controller, the modern sensors and actuators, to the pressure-controlled recirculation technology, including air loading, and extending to the high-pressure water rinsing system.

Area of application

The shuttle table unit permits the single-level processing of parts on two support platforms, which move back and forth in a pendulum mode. This offers both continuous operation and short cycle times.

For larger parts, the two shuttle tables can be connected to one large worktop. The shuttle table unit consists of a robust chassis section (fitted with adjustable leveling feet), with two movable worktops in coated multiplex and attachment holes for securing the workpiece support or the workpiece itself.

The shuttle table is optional and can be supplied subsequently for self-assembly to the dosing cell.
