The new DM 50x – an Overview Automated System Solutions for Advanced Material Dosing The illustrated system configuration with the DM 503 mixing and dosing machine for three components stands for the reliable interaction of all system components, as well as the highest levels of process stability, precision and efficiency. Preparation of the materials, e.g. air loading for the seal foaming process or degassing for bubble-free potting, is carried out in the material pressure tanks. The automatic refilling stations stand ready for the supply of materials and their handling. The 2C reactive...

The dosing machine cabinet contains all...

The Sonderhoff Equipment Portfolio Perfectly Matched Components The design of an optimum production process requires the perfect matching of the component processing, automation and control processes. This requires a good deal of experience and the highest precision when it comes to detail. Mixing and Dosing A machine concept is only as good as the components used. A control system can be as precise as you want it to be. However, the components must be able to implement the target values. For example, the material pressure-stabilizing recirculation system, a sophisticated mixing head...

Reliable Mixing and Dosing Experience and Precision in every Machine Component With our SONDERHOFF DM 50x series equipment portfolio, we offer automation solutions for the mixing and dosing of 2-component reactive materials – especially polyurethanes, silicones and epoxy systems. For this, the material components have to be prepared, i.e. stirred in the tank and loaded with air, and then conveyed to the mixing head. In the mixing head, the components are then mixed dynamically and the liquid sealant system is dosed in precise quantities. Each of the process steps involved has its own...
