The potting of components is chosen to protect sensitive components, eliminate dust, temperature-related influences, moisture or increase service life. The encapsulation of electronics is also one of the applications of this dispensing process. Components are filled or poured with low-viscosity potting materials such as polyurethanes (PU), epoxy resins (epoxy), silicones.

The material preparation should be selected ideally for the potting medium and according to the application. The reaction casting resin is filled directly into the product through a dispensing head (1K, static, dynamic). Subsequently, curing takes place via time, temperature, UV or humidity.

Typical applications are pacemakers, cable bushings, sensors or electronic components.

Potting applications

During potting, components are filled with a low-viscosity potting material to protect them from external influences.

Vacuum potting

By potting under vacuum, components can be optimally protected from external influences. Before the potting process, air and moisture are removed from the components by vacuum. Components with geometries that are difficult to vent, coils, transformers or wound goods can be potting free of air bubbles. Potting under vacuum guarantees an even distribution of the potting material.

Curing & preheating

Industrial ovens

The ovens are used to cure potting compounds such as epoxy resins, polyurethanes and silicones or to preheat components to a specific temperature. For optimum potting results and the shortest possible cycle time, the components are in many cases preheated and the dispensed product is cured in a horizontal conveyor oven to ensure handling.
