ZAHORANSKY Automation & Molds GmbH has entered into a partnership with the Swiss company KEBO AG. The result of this collaboration is a new mold concept for the production of pipette tips, which features a double quick-change system. Both 8x8 modules on the nozzle side and the cores on the ejector side can be changed in just a few steps to allow production to be resumed immediately when mold cores and wear bushings are replaced.

Michael Schmidt, Managing Director ZAHORANSKY Automation & Molds GmbH, comments: "Pipette tip molds are ‘divas’ from a production point of view – very sensitive in the process – and require precise handling: The challenge is that long thin cores are immersed in a counter-bearing and injected on one side. With our new design, all maintenance activities can be completed in a few minutes on the injection molding machine thanks to these quick-change systems on our mold."
The new 64-cavity pipette tip mold with double quick-change system was developed together with Swiss-based KEBO AG. The company, based in Neuhausen am Rheinfall, has more than 40 years of experience in developing hot runner technology solutions. Says Gerold Keller, owner and CEO of KEBO AG: "We are very pleased with this special partnership between two mold makers who complement each other ideally for this project. As a result, we were able to achieve our common goal in a short development time ('time-to-market') and improve the technology for manufacturing pipette tips in a way that significantly reduces production costs and significantly improves service life for manufacturing companies."
