l Umbra Cuscinetti, an East Granby, CT-based arm of the Umbra Group, has created ballscrews for electromechanical injection molding machines. These ballscrews operate in high pressure environments and are expected to provide plastic mold shops with longer life, while functioning solidly under very high loads. According to the company, Umbra has begun using Cerbec silicon nitride balls from Saint-Gobain Ad-vanced Ceramics in order to address issues of longevity and repeatability in poorly-lubricated molding applications. Ballscrews with Cerbec components are capable of handling loads up to 1,800 KNewton and have axial speeds between 150 and 160m per minute, with acceleration capabilities in the range of 3G.
