Absolute process reliability

LED light potting

Bubble-free dispensing of silicone and polyurethane

Compared to an incandescent light bulb, an LED lamp consumes less energy for the same light output, generates less heat and is significantly smaller and less susceptible to shocks. Furthermore, it has a much longer life. The increasing use of LEDs is even expanded by applications that would not be possible without potting. The potting compounds used for such applications are polyurethane (PU) or silicone-based two-component solutions. They are intended to protect the LEDs against extreme temperatures, moisture, vibrations and mechanical damage. LEDs are also used in fields where maximum reliability is required and maintenance-free operation plays an important role.

Intelligent solutions by DOPAG
The comprehensive DOPAG portfolio of two-component compound metering and mixing systems for manual and automated application ensures absolute process stability. The benefits offered include the precise maintenance of the specified mixing ratios, a high metering accuracy, a high flow rate and bubble-free application that is the decisive prerequisite to ensure stable potting. As seen both from the ecological and economical perspectives, DOPAG metering and mixing systems promote a sustainable production process. The materials to be processed are mixed based on the specific demand which means material consumption and waste disposal costs can be reduced. The use of flushing agents is not required.

Absolute process stability
LEDs are used for various applications that range from flashlights and traffic lights to headlamps and taillights in vehicles and to street lighting. They can also be found in lighting systems for damp interiors and swimming pools and are used for creating optical effects in showcases. The potting compound is selected depending on the requested properties such as hardness, vibration resistance and thermal stability. Different colors are possible as well. For translucent LED applications, a transparent or opaque clear potting compound is used.

Beim Verguss werden hauptsächlich Gießharze wie Silikone, Polyurethane oder Epoxidharze in flüssiger Form verwendet. Für die Verarbeitung bietet DOPAG verschiedene Dosier- und Mischsysteme an.

  1. eldomix


    Die Anlagen der Baureihe eldomix 100/600 sind spülmittelfreie, kompakt aufgebaute Zahnradpumpen-Dosieranlagen.

  2. variomix


    Die Anlagen der Baureihe variomix sind spülmittelfrei und kompakt aufgebaute, pneumatisch oder hydraulisch betriebene Kolbenpumpen-Dosier- und Mischanlagen.

  3. vectomix


    Vectomix wird für die Verarbeitung von Mehrkomponenten-Medien eingesetzt. Hierzu werden aufgrund der Kompatibilität und Modularität zwei vectodis Kolben-Dosiereinheiten, auch unterschiedlicher Baugröße, verwendet.

Mit der dynamicLine und dem neu entwickelten dynamischen Mischkopf bietet DOPAG eine effiziente Lösung für sämtliche Anwendungen im Bereich Dichtungsschäumen.

  1. Dynamischer Mischkopf

    Dynamischer Mischkopf

    Der dynamische Mischkopf mit neuer Ventiltechnik wurde für die Vermischung von flüssigen bis hochviskosen polymeren Reaktionswerkstoffen zum Schäumen, Kleben, Dichten und Vergießen entwickelt.
