Exclusive for Zinc Die Casting (Not for use with Aluminum, Magnesium, Brass, Lead or other non-Zinc materials)
DME Runner Spreaders for Zinc die casting were developed after extensive laboratory research. The results of this research proved that the metal feed system could be improved by extending the runner into the spreader area.
DME Runner Spreaders are manufactured to permit the die maker to machine one or more runners into the spreader. This improved metal feed system provides faster cavity fill, decreased cycle time, reduced porosity, improved part quality, less shot weight and optimization of machine capacity. In some cases, thin wall parts that cannot be produced by other means can be successfully die cast by using Runner Spreaders. Available in short or long styles. Please see the catalog page for more details.
Please note that DME does not offer special Runner Spreaders. For instructions on allowable machining or modifications for Runner Spreaders, please see packing slip. Modification to the Bushing is not permitted. Modification to the Bushing, or, modification to the Runner Spreader that exceeds that shown on packing slip, may cause bodily harm to the end-user. Do not use plastic baffles in a Runner Spreader.
