Highly Abrasive Materials Reliably Applied in Very Small Quantities
eco-PENs that are already in operation can be upgraded in a very short time, thanks to the spare parts kits. Test result after 120 hours dispensing: The standard rotor on the right, with a hard chrome layer, shows signs of wear over time when used with highly abrasive materials, depending on the process. Detail view rotor wear: Standard rotor left … Read More
Potting of miniature connectors
High-precision dispensing for complete process reliability Miniature connectors must be absolutely reliable and have secure contacts. Two-component potting compounds such as PU, epoxy or silicone are particularly suitable for potting miniature connectors. They are especially impressive compounds due to their wide range of applications. Increasing miniaturisation of performance electronics and improved sensor technologies increase the demands on dispensing equipment, i.e., … Read More
Bioinspired Artificial Heart Valves Made by Silicone Additive Manufacturing
preeflow® eco-PEN300 “prints” synthetic implant In an additive manufacturing process, virtual heart valve models are created with the aid of a CT scan and a preeflow eco-PEN300 one-component dispenser: Fergal Coulter from the “Complex Materials Group” of ETH Zurich undertook research for medical technology – more precisely for the additive manufacturing of artificial heart valves. They were manufactured using custom … Read More

„Diamond Coated Rotor“ for preeflow
A new standard in the micro dispensing of highly abrasive Materials within the 1-component and 2-component range 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 … Read More
Dispensing anaerobic adhesives
Long-term tests with preeflow dispensers using one-component adhesives 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 … Read More
