Dosing cell 3E SIL
Dosing cell with the highest process stability for automated sealing, bonding and potting of 2K silicone systems
The SONDERHOFF 3E SIL dosing cell is a low-pressure mixing and dosing machine that is intended for use with 2-component silicone material systems for seal foaming, bonding and potting industrial parts. The liquid, medium- and high-viscosity 2K silicone material systems undergo exact processing, dynamic homogeneous mixing and precise dosing and are applied to the parts in a fully automatic process using FIPFG technology (formed-in-place foam gasket).
The 3E SIL was designed as a modern, compact dosing machine for standard applications and for the most frequently used application conditions.
In addition to the 3E SIL, we offer two other machine types. These are the 3E PUR for 2K polyurethane systems and the 3E FLEX as a customizable dosing cell for optional configurations.
All three machine types of the 3E dosing cell are equipped with DM 50x technology and different precision mixing heads from the MK 800 series, which feature impressive innovative improvements. They ensure maximum process stability for the fully automatic dosing of the 2K material systems used. An attractive entry price enables very short payback periods, and the high degree of standardization also shortens delivery times.
Optimized process evaluation and control
The 3E SIL dosing cell is equipped with the precision mixing head MK 825 PLUS. The sensors installed in the mixing head measure data for continuous monitoring and compliance with critical process parameters.
The machine operator therefore has access to a comprehensive data-base. It also enables preventive maintenance of wearing parts. The automatic logging of all system, material and process data ensures the transparency of the production sequence at any time.
Furthermore, we offer various technical services that ensure con- tinuously high machine availability.

Place, plug & work!
Once the 3E SIL is removed from its transport container, production can start without much preparation. Power, water and compressed air just have to be connected and the two material components of the chosen 2K silicone system filled into and prepared in the separate material pressure tanks. With the 3E SIL, even small and medium quantities can be produced very economically.
The dosing machine is equipped with a manually operated lifting door. Accordingly, the machine is CE-compliant, so that no additional safety fences or light barriers are required – this boosts efficiency, saving space and costs.
With the dosing cell SONDERHOFF 3E SIL (Economic, Efficient & Ecological), you can get to work right away: Place, plug & work!
SONDERHOFF 3E SIL
Cellular mixing and dosing machine for processing and dosing 2K SIL systems
The mixing head is precisely guided within the travel range of 2,500 x 1,250 x 250 mm (x/y/z) by a 3-axis linear robot integrated into the cell. The linear robot with toothed-belt drive is characterized by its good stiffness. This allows the mixing head to be guided over the part being processed with very high repeatability.
Operating the dosing machine 3E SIL
The machine operator places one or more parts on the prepared workpiece holder within the working area of the dosing cell. He then closes the lifting door with a hand lever at the front of the machine. The fully automatic application of material to the part can start. For this purpose, the CNC-controlled MK 825 PLUS precision mixing head moves over the part contour.
To remove one or more parts after the dispensing process, the machine operator opens the lifting door using either the hand strap mounted there or the lever.

Control Cabinet
The switch cabinet is the expandable future-proof control center of the SONDERHOFF 3E SIL dosing cell with DM 50x technology. It includes the electrical distribution as well as the control and safety technology for the dosing machine and the CNC control of the 3-axis linear robot installed in the cell.
Dosing machine components and material containers
The dosing machine components of the SONDERHOFF 3E SIL dosing cell are mounted on the side of the cell. This is where e.g. the precision gear pumps, compressed air connection and dryer, and the maintenance unit and high-pressure water unit for mixing head rinsing are located.
Multi-functional MP 2 mobile panel
The SONDERHOFF 3E SIL dosing cell is designed to enable the operator to perform a wide variety of tasks easily and safely. The system is operated via the easy-to-use, multi-functional Sonderhoff MP 2 mobile panel with integrated 10.1“ touchscreen. This makes the contour programming of components significantly simpler.
Optional shuttle table
The SONDERHOFF 3E SIL dosing cell offers an attachable sliding table with manually shifting mounting plates as an alternative option for placement and processing of industrial parts for sealing, bonding, or potting. With this solution, a machine operator loads the two mounting plates with the components in an alternating sequence.
Optional automatic refilling stations
The 3E SIL dosing cell can optionally be equipped with a refilling station for automatic material supply. This ensures material-specific preparation, homogeneous consistency and a continuous supply of materials to the component containers of the mixing and dosing system – without exposure to or contamination of the products to be filled.
