EWIKON will introduce Ecomodul at NPE 2006, the new hot runner system for large parts, which will set new standards in flexibility and economy. The system targets the automotive industry as well as manufacturers of white goods and large containers. All components are fully standardized. The EWIKON valve gate system with synchronized valve pin operation especially targets applications with a high number of cavities with close cavity spacing and small part weights. The NVE product is designed for use with EWIKON’S slim nozzles with 3 mm and 4.5 mm flow channels (nozzle shaft diameter of 9.5mm and 13mm respectively). All needles are fixed in one actuator plate, which is operated either by a horizontal pull rail system using the cam activation principle or by hydraulically or pneumatically actuated pistons incorporated in the top clamp plate. This method offers several advantages. When using the slim HPS III-VT nozzles with 3-mm flow channel, minimum cavity spacing of 12 mm is possible. Thus, an extremely compact multi-cavity mold design becomes possible. Furthermore an absolute simultaneous opening and closing of all valve pins is guaranteed. EWIKON also announces a new electrical needle drive for valve gate systems that has been designed for use with HPS III-NVE 1 and HPS III-NVE 2 valve gate systems with needle drive positioned in the clamping plate. As a clean needle drive version it offers an extreme suitability for cleanroom applications.
