A Variety of Dispensers for Micro Dispensing Applications

Covering the entire production process with one technology

Dispensing small and smallest quantities with volumetric precision and speed often presents major challenges for companies in the medical technology, automotive, electronics, biochemistry, and photonics industries. It is not uncommon for industrial manufacturing companies to integrate various dispensing systems from different suppliers into their lines in order to meet the chemical and physical properties of all materials to be mixed and dispensed. The preeflow brand, whose dispensing technologies can process silicones, adhesives, greases, oils, resins, sealants, or pastes and much more in the currently widest possible spectrum, works reliably and accurately even at extremely high cycle rates.

One-component dispensing systems (eco-PEN), spray dispensers (eco-SPRAY) and two-component variants (eco-DUO) are available and based on the operating principle of progressive cavity pumps. They are equally suitable for manual operation and fully automated use. The so-called endless piston principle ensures pulsation-free and purely volumetric dispensing and delivers material of varying viscosity, unchanged throughout the entire process.

The above-mentioned designs are continuously adapted by an internal research and development team to an increasingly wide range of industrially processable materials, considering parameters such as material composition and its viscosity. The dispensing of adhesives – light-curing, thermosetting, anaerobic, shear-sensitive – is just as simple as the application of solder pastes, the application of thermal pastes or the dispensing of LED resins, to name but a few. The programmable suck-back effect guarantees a clean, controlled thread break with any material, without dripping.
