An incredible 40 pallets with an estimated 20,000 outer cartons have recently been stored at preeflow® - the end of a journey with which the company has actively advanced its previously-set sustainability goals for packaging materials in recent years. "Due to the COVID pandemic, we were not able to implement many things as quickly as planned. But now we have reached our ...

According to statistics, the proportion of connected cars in the USA will be around 97% in 2035; the figure could be similar in Europe. An increase in the level of automation across the entire value chain in automotive manufacturing has already been evident in recent years. Starting with the OEM and the system and component suppliers and extending up to the tool and die ...

One of the most important parameters in a dispensing process is the resulting dispensing pressure. The optimal conditions for a functioning and process-safe setup can only be achieved by controlling this pressure. The best example where the dispensing pressure becomes a critical parameter: The application of highly viscous and filled material in combination with high f...

Acetone, alcohol, paint or epoxy resin: These are just a selection of substances whose chemical properties challenge mechanical engineers in the implementation of customer-specific systems. However, POM plastics - technically known as polyoxymethylenes or polyacetals - are not always the best choice for components and parts. The reason is that they can become brittle ove...

preeflow's newest member of the portfolio simplifies the emptying of double chamber cartridges. eco-FEED is a fully automatic, pneumatic cartridge emptying system that takes over the squeezing function respectively the steady emptying. At the same time, it achieves a particularly precise and gentle material supply to the eco-DUO dispenser in a process-safe manner. It is ...

TQ Systems, in Durach, manufactures collaborative robots that assemble themselves - among other things, with the help of preeflow dispensing technology. The precise eco-PEN and eco-SPRAY dispenser systems take care of the lubrication of gears, for example. The basic idea of letting the robots build themselves arose at TQ from the question: There is manual production and ...

preeflow introduced the Diamond Coated Rotors (DC rotors for short) just a few months ago and the demand is already exceeding the expectations of the microdispensing technology specialist.

In the sports sector there are fitness trackers, sports watches, smart shoes, and smart belts. An obvious trend in fashion is smart clothing and e-textiles. Bu...

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 t...

Precise, repeatable, and process-safe applications in the field of micro dispensing have always been the emphasis of the preeflow by ViscoTec brand. Thanks to the volumetric endless piston principle, almost all low to high viscosity materials can be processed. Solids-laden fluids, or filled material with, in some cases, highly abrasive properties are currently gaining...

The word anaerobic means "without air" and therefore describes one of the two curing mechanisms in the handling of one-component adhesives: Air exclusion. Combined with the second mechanism, namely contact with metal ions, a rapid polymerization of the material is achieved. Due to their easy handling and fast curing, anaerobic adhesives enjoy great popularity. The one-co...
