puttymix: Metering and mixing 2K putty materials
For perfect surface protection of rotorblades
The finishing process of rotor blades has become more and more important based on the increasing blade lengths. To protect the surface of the rotor blade particularly well, small unevennesses are filled with putty material at the end of the production process. Based on decades of experience in metering and mixing a wide variety of materials, DOPAG has developed a specific system, the puttymix, which perfectly meters and mixes the two-component putty material with its high viscosity variance. An optional high speed injection of an accelerator using needle metering valves is possible. In addition, the metering and mixing system can be used to apply pore fillers.
