This would otherwise cause the preform – and therefore later the bottle – to not being completely transparent at this point. To better split the two temperature areas of nozzle and cavity, the insulation per- formance was enhanced by a titanium ring. The result was a reduced energy requirement thanks to the more efficient separation between the hot and cold areas. When comparing the – apart from the hotrunner – identical tools, power con- sumption of the Vulcan model was higher by a double-digit percentage. Further power savings can be achieved by using a HP gate insert, which directs the cooling to the mould contour and prevents unnecessary dissipation of heat from the hotrunner nozzle. This allows for double savings: less heating required at the nozzle tip and lower cooling performance of the cooling water system. Also the owners of an existing MHT tool can benefit from this savings potential, simply by replacing the exist- ing nozzles with the Vulcan variety. With the change, they simultaneously gain an increased amount of flexibil- ity. The two-part nozzle with tip inlay makes the exchange particularly easy – be it in case of wear and tear or if a new diameter, a new design or different materials are required. Pre-alignment of the valve stem is possible as well. To summarise, the Vulcan hotrunner components of MHT combine tightness with easy maintenance and energy efficiency. www.mht-ag.de 3 Y E A R S NBĔ H?Q ;AĔ I@ J;=E;ACHĴ HIGH FLEXIBILITY...
