SMART Mixing and Dosing

Dynamic Mixing Makes the Difference

The greatest possible material homogeneity after mixing 2-component material systems with different viscosities can only be achieved with dynamic mixing, especially in the case of demanding, asymmetrical mixing ratios. This is handled by our MK 800 mixing heads.

Material Preparation Begins with Stirring

The material is conditioned according to the specific application requirements in the single- or double-walled material pressure tanks. Depending on the material system, it may be necessary to selectively load the A-component with air, for example to obtain a fine-celled foam, or – just the opposite – to degas it for bubble-free clear potting.

The agitator therefore has the function of not only counteracting sedimentation, but also of ensuring uniform air loading or degassing and temperature distribution.

Recirculation for a Constant Flow of Materials

Highly precise dosing components in a user-friendly dosing system design. The dosing machine cabinet is a compact, self-contained unit that contains all the components important for the dosing process: the precision gear pumps with servo drive for dosing the material components, the ecological high-pressure water unit for rinsing the mixing head, the Peltier cooling device for controlling the temperature of the mixing head and the recirculation hoses, and the LBM 3 air loading measuring device and the compressed air dryer.

Precise Refilling for Continuous Material Supply

When used in fully automated manufacturing processes, automatic refilling stations ensure material-appropriate preparation, homogeneous consistency, and a continuous material supply to the material pressure tanks of the mixing and dosing system – without exposure or contamination of the products to be filled. Some of the refilling stations are equipped with an automatic lifting device for greater ease of operation and more safety at work and in the plant. Production interruptions are thus a thing of the past.

Optional Special Devices to Increase Process and Dosing Accuracy

Optional special features and devices can be ordered for the SONDERHOFF SMART dosing cell with DM 50x technology to further increase process and dosing accuracy, such as the AIR-CLEAN pneumatic nozzle cleaning, the NOZZLE-CONTROL measuring unit for checking the dosing nozzle position, the WEIGHT-CONTROL device for dosing discharge quantity, the Peltier mixing head cooling system, the LBM 3 air load measuring and control unit, and the sensor mounted on the mixing head for part detection.
