Mold-Masters (Georgetown, ON) offers an electric valve gate (EVG) with a very high closing force which, in some cases, is almost two times higher than pneumatic actuators. The unique design of the actuator allows for pin movement in less than 0.1 second and overall molding cycles below 1 second. EVG is up to 90 percent more energy efficient than traditional actuators for valve gates and is ideally suited to cleanroom applications. Plate costs are reduced because there is no requirement for gun-drilling of air or hydraulic channels, plugging of the gun-drilled lines or need for water/hydraulic fittings. The EVG system is standardized and modular in design. The simple touch screen EVG controller allows the molder the ability to easily sequence the valve gates or shut-off a given cavity without altering tip heats. Systems are available in 75 and 55 mm piston sizes to allow for tight pitch applications.
