#13 - Eliminating micromolding cold runners

As medical devices get smaller, manufacturers require innovative, more reliable ways to produce small and micro-sized plastic components. Conventional approaches are costly, inefficient, and often unable to deliver the required precision and speed. A new micro-injection molding technology called Isokor improves speed and precision by eliminating molding inefficiencies.

Most micromolders use cold runners to manufacture micro-sized parts, ejecting the cold runners with the parts after each molding cycle. Parts must then be detached from the cold runners, which are either scrapped or converted back into granules to feed back into molding machines. Though cumbersome, the process was the only means of making micro-sized plastic parts. Until now, companies procuring micro parts had no choice but to live with significant drawbacks and costs associated with using cold runners.
