Hot runner suppliers unite.

Barnes Group Inc., Bristol, Conn., an international aerospace and industrial manufacturing and service provider, last month agreed to buy Männer of Bahlingen, Germany, a moldmaker and supplier of hot-runner valve-gate systems. Männer also builds a unique micro-molding machine. Männer USA is located in Lawrenceville, Ga. This is Barnes Group’s second plastics acquisition: Last year, Barnes purchased Synventive Molding Solutions, Peabody, Mass., another major supplier of hot-runner systems and components.
