3E FLEX Dosing Cell
The configurable entry-level model for standard applications with 2K polyurethane or silicone systems for foam gasketing, bonding and potting
The SONDERHOFF 3E FLEX can be flexibly configured according to your different manufacturing needs. You can choose whether you want to use the 3E FLEX to process and dispense polyurethane- or silicone-based 2K material systems with asymmetrical or symmetrical mixing ratios. All system components are installed on one chassis, which considerably simplifies transport and commissioning: set up, connect and produce – place, plug & work!
The dynamic high-performance mixing heads MK 800 PLUS or MK 825 PLUS available for the 3E FLEX are guided by the linear robot of the dosing cell in a maximum traversing range of 2,500 x 1,250 x 300 mm (x/y/z). The 2K material system used is mixed dynamically and homogeneously in the mixing head and precisely dispensed in the defined mixing ratio – a prerequisite for high quality.
If desired, the optionally available hand scanner can be used to select the dispensing and CNC program for the part to be processed. The CNC-controlled mixing head then ensures repeat-accurate and fully automatic Formed-In-Place (FIP) material application to the part.
The machine operator is separated from the working area by an automatic high-speed door which makes the dosing cell CE-compliant.
The material pressure tanks on the chassis of the dosing cell are available in two sizes and can be flexibly combined, either both tanks with 24 or 44 liters each or as a combination with 24 and 44 liters. For a continuous material supply, automatic refilling stations for drums or containers are optionally available.
The components are positioned either manually in the work area of the dosing cell or on the optional sliding/shuttle table. For oversized components, the two sliding tables can be connected to form a large work table.
Another advantage for more flexibility is the variable table height in the dosing cell, allowing component heights from 300 to 600 mm. The standard work/table height is 1,000 mm and can be reduced to 700 mm, for example, to integrate manufacturing automation. If required, a transfer belt running through the cell can be installed for clocking in and out the components.

The compact class for 2K polyurethane and silicone applications
Place, plug & work!
Once the 3E FLEX is removed from its transport container, production can start without much preparation. Only connect the power, water, and compressed air supplies and prepare and fill the two material components of the selected 2K polyurethane or silicone system into separate material pressure tanks. With the 3E FLEX, even small and medium quantities can be produced very economically.
The dosing machine is equipped with an automatic high-speed door. Accordingly, the machine is CE-compliant so that no additional safety fences or light barriers are required – increasing efficiency and saving space and costs
With the dosing cell SONDERHOFF 3E SIL (Economic, Efficient & Ecological), you can get to work right away: Place, plug & work!
Operation of the 3E FLEX dosing machine
The machine operator places one or more parts in the work area of the dosing cell on the prepared workpiece fixtures. He then closes the high-speed door by pressing a button so that the fully automatic material application can start. For this purpose, the CNC-controlled
MK 800 PLUS or MK 825 PLUS precision mixing head moves over the part contour to apply the material.

Dosing machine components and material tanks
In the SONDERHOFF 3E FLEX dosing cell, the dosing machine components are attached to the left side of the cell, for example: the precision gear pumps, the compressed air connection and dryer, the maintenance unit as well as the optional Peltier device for mixing head cooling and the high-pressure water unit for ecological mixing head rinsing.
The double-walled material pressure tanks in the optimized sizes are also mounted on the cell chassis on the left side, either for the asymmetrical mixing ratios of the A and B components of the 2K polyurethane systems or for the symmetrical mixing ratios of the 2K silicone systems. The material pressure tanks of the 3E FLEX can be flexibly configured as required, either for both material components 24 or 44 liters or in combination for one component 24 and the other 44 liters.
For heating or cooling the material in the pressure tank, we offer an optional precision temperature control unit, which can be used to influence the reactivity behavior of the 2K material systems.
The material pressure tanks are equipped with various sensors that indicate whether the pressure tank needs to be refilled or is completely empty. For the material pressure tanks, an optional extension with an automatic refilling station for continuous material supply is possible on request. For this case, there is an overfill protection on the pressure tanks.

Air loading, temperature control and material evacuation
Air loading in the material pressure tank helps to produce the desired physical properties and cell structure of the foam. By adding compressed air to the material component, the density can be influenced.
Optional: temperature control unit for heating or cooling the material in the pressure tank
Air loading in the thin film process
Compressed air cushion acts on material surface
Druckluftpolster wirkt auf Materialoberfläche
Material is continuously conveyed from the pressure tank bottom through a riser and fed back onto the cone-shaped surface as a thin film. Due to the air loading, the density changes and the material becomes lighter.
Material evacuation in the thin film process
Vacuum acts on the material surface.
Vakuum drückt auf Materialoberfläche .
Material is continuously conveyed from the pressure tank bottom through a riser and fed back onto the cone-shaped surface as a thin film. This process continuously reduces and completely dissolves the air bubbles in the material.
Automation and Configuration of the 3E FLEX Dosing Cell
Another advantage for more flexibility is the variable work/table height in the dosing cell, allowing part heights from 300 to 600 mm. The work/table height is 1,000 mm as standard and can be reduced to 700 mm, for example, to integrate production automation.
For this purpose, the cover plate on the front and rear of the dosing cell can be removed so that, if required, a transfer belt running through the cell can be installed for clocking in and out the parts.

Optional Shuttle Table for the 3E FLEX Dosing Cell
As an option, the parts can also be loaded on an attachable sliding/shuttle table by manually moving the mounting plates. With this solution, a machine operator loads the two mounting plates with the parts in alternation. The parts are positioned in workpiece fixtures that are mounted on the coated multiplex mounting plates.
