Bubble-free filling of oil dampers

Monday, November 27th, 2017 von admin

Filling of oil dampers in low-volume and pilot production is mostly manual work. There is a lot of potential for improvement by a compact, flexible dosing system which includes a micro metering pump. This self-priming micro annular gear pump can work without an application of compressed air to the reservoir.

On the one hand, this saves the cost of compressed air including the necessary devices and, on the other hand, avoids the introduction of compressed air into the silicone or hydraulic oil. The medium can be filled bubble-free, gently and without loss of quality.

The less the amount of material to be mixed, the greater the challenge for the dosing system: Due to the World’s increasing miniaturisation in areas such as electronics and the associated high demand for ever smaller and more precise dosing, preeflow has developed the eco-DUO330. This system provides the answer to numerous questions from application engineers, material manufacturers, plant engineers and product developers. Be it in medical technology, optics and photonics, the manufacture of electronic components or in the field of biochemistry and the production of semi-conductors.

Adherence to the exact mixing ratios of the 2 component materials and its precise coverage can greatly influence the processes and applications from time to time. Even small deviations can negatively affect the desired results. Compounds harden only partially, adhesive bonds do not reach their load limit and, in the worst case, chemical reactions from the materials could have an unforeseeable impact on the user.

With the newly developed eco-DUO330, dosing quantities of 0.005 ml (per shot) is achievable. Irrespective of temperature, time, pressure and viscosity – dosed as a dot or bead. Therefore, the smallest quantities can be created at that very moment. The microprocessor-controlled system creates a dosing accuracy of ± 1 % and repeatability of over 99 %. And this whole process is reliable and reproducible.
