Compact cell

With its semi and fully automatic dosing systems, Drei Bond can be integrated into a wide range of dosing technologies. The selection of the ideal application technique takes place after a thorough review of the application, the component geometry, dosing medium and your quality requirements. Both classical pressure/time dosing systems and volumetrically controlled systems are available in order to achieve the best possible dosing procedure. In addition, Drei Bond offers a particularly flexible component holding fixture that allows different workpieces to be processed in a very short period of time.

Greasing, oiling

Drei Bond supplies equipment for the greasing or oiling of surfaces, holes, internal threads or cylindrical surfaces. The valves make it possible to apply the media finely, smoothly and evenly and even circumferentially (360 degrees).

Cyanoacrylate adhesives

Cyanoacrylate adhesives are instant adhesives (commonly known as superglue), which are characterized primarily by their curing speed – generally within seconds. They can be used for sealing and bonding almost all materials and are particularly suited for small and medium-sized areas. Drei Bond also offers specific products for materials which are difficult to bond, such as Teflon.
