At NPE2015 this month in Orlando, new hot-runner technologies from Synventive Molding Solutions, Peabody, Mass., will include additions to its activeGate line of controls for valve-gate pin movements. The nuGate and hGate technologies provide full
pneumatic and hydraulic control, respectively, of the pin movement—speed, acceleration, and stroke in both the opening and closing directions. These complement the similar capabilities of electrically actuated eGate version.

Also new at the show is a line of Plug ‘n Play modular actuators for valve gates (photo). They are pre-plumbed, pre-wired, and pre-tested. They have patent-pending easy-access pin adjustment and automatic bleed, as well as easy pin decoupling, improved thermal properties to prevent overheating, and a cooling plate with removable plug for easier cleaning.
