Mold specialist Männer highlights nozzles engineered for medical applications


German manufacturer of molds and hot-runner systems Männer (Bahlingen am Kaiserstuhl) had a lot to talk about at NPE2015 last week in Orlando, FL. The company is celebrating its 50th anniversary, and it has some festivities planned for later in the year that it will announce in the next couple of months. It also has a three-year plan to significantly expand its moldmaking capabilities at its U.S. plant in Lawrenceville, GA, and bring one aspect of the so-called German model—notably, an emphasis on vocational training and apprenticeships—to our shores. We will have more on that shortly. In the meantime, Männer presented some recent product developments at NPE2015 that deserve mention.

The nozzle combines the benefits of a hot-runner system with the original cylindrical valve gate, says the company: defined pin opening and closing; cosmetic gate quality; resin savings; and process repeatability. Syringe barrels and other applications with long, narrow cores and an opening on both ends, benefit from this technology.
