Highest process stability in fully automated processing and dosing of sealing foams, adhesives, and potting compounds

World premiere: Henkel presents new generation of dosing machines

Köln – Henkel offers new DM 502 generation of dosing machines with the newly developed MK 825 PRO mixing head. The many innovative improvements serve one purpose: maximum process stability in the fully automatic processing and dosing of sealing foams, adhesives and potting compounds. The result is high-quality sealing, bonding or potting of components.

With the Sonderhoff System Solutions (S3), Henkel offers its customers tailor-made sealing, bonding and potting solutions, with material, machine and automation from a single source.

The new mixing head has a maintenance-friendly, conical V-design and has been consistently further developed on the basis of the predecessor model MK 600, which has proven itself for 20 years, with many improvements and innovative features. This ensures maximum process stability for fully automatic sealing, bonding and potting with Formed-In-Place (Foam-Gasket) technology.

Broad data basis for optimized process evaluation and control

The sensors installed in the DM 502 dosing machine and the MK 825 PRO mixing head measure a wide range of data for seamless monitoring and compliance with critical process parameters, such as temperature, degree of air loading, sensor-monitored axial position of the agitator shaft, automatic control of the DVS stroke adjustment, and sensor-monitored needle positioning of the dosing valve. This provides the machine operator with a comprehensive database on the entire FIP(FG) application process. It enables fast and precise data analysis for optimized process evaluation and control as well as predictive monitoring of material application processes and preventive maintenance of wear parts.

Innovative mixing head for the highest demands

In addition to better evaluation options, the new mixing head achieves outstanding dosing and process quality for even better results. In order to ensure an always optimal application process and higher machine availability, the new DM 502 dosing machine and the MK 825 PRO mixing head allow important machine parameters to be measured by integrated sensors:

- automatic positioning and speed control of the agitator in the mixing chamber,

- automatic stroke adjustment of the agitator with stepper motor and position monitoring,

- automatic air loading for optimum cell structure of the foam seal,

- automatic, sensor-monitored position of the dosing needle made of high-performance plastic in the shot and recirculation valve.

In addition, a greatly improved temperature control system has been introduced.
