The brand preeflow® was created in 2008 by ViscoTec. Since then, the microdispensing products of the eco-PEN and eco-DUO series have been successfully used in dispensing applications worldwide. preeflow® systems stand for volumetric, repeatable and economical dispensing of low to high viscosity liquids. They can be used individually as well as easily integrated into semi or fully automated systems. The fluids can range from watery to pasty, from self-lubricating to abrasive, from thixotropic to dilatant. There are almost no limits to the types of materials which can be dispensed. Customer satisfaction...

TECHNOLOGY & USP HOW IT WORKS EVEN WITH THE MOST SOPHISTICATED MATERIALS MADE IN GERMANY From the initial idea to the outgoing goods inspection: All steps in the process are developed and implemented at the headquarters in Töging. In addition to the quality feature “Made in Germany“ and the “Think global, act local“ approach, we at preeflow® not only ensure the quality of the systems, but also offer optimum coordination and process reliability in all projects. THE ENDLESS PISTON PRINCIPLE We have more than 25 years’ experience in the dispensing of fluids. This comprehensive know-how in dispensing...

- INTERESTING FACTS DROPLET SIZES 0,25 pi is the smallest dose quantity possible with a preeflow® dispenser. As droplets on a substrate with a contact angle of 90°, this has a diameter of only 0.493 mm. Larger droplets are possible at any time during the process thanks to the technology used. Exemplary representation of droplet sizes: BEAD STRENGTH Due to pulsationfree dispensing technology, highquality beads can be produced with preeflow® dispensers. Beads with a diameter of less than one millimetre can also be produced. With flow rate linked to speed of movement, consistent and stable beads...

ONE SENSOR, MANY APPLICATIONS DESCRIPTION Incorrect dispensing affects the quality of the entire process and leads to waste of the material. This can be due to a constriction or blockage within the dispensing needle, an incorrect distance to the substrate or air trapped in the material interrupting the material application. By continuously monitoring of the dosing process with the flowplus-SPT 16, errors can be detected, and a stable process established. Thanks to the standardized Luer-Lock connec tion, the high sampling rate of 3 kHz as well as the integrated pressure sensing and compact size,...

SYSTEM ILLUSTRATION Designation The 2-component mixing and dispensing systems from preeflow®: true volumetric output for 2-component materials. The smallest quantities of 2-component fluids and pastes are precisely mixed and dispensed. The mixing ratio is set to the second decimal place by targeted control of the individual components. A clean, process-reliable dose is achieved regardless of fluctuations in viscosity. The preeflow® devices of the eco-DUO series are characterised by controlled thread break-off thanks to the suck-back effect, process reliability due to pressure monitoring and further...
