Space-saving Solution for Multi-cavity Molds
The new Z3280/.../S Multimodule from Hasco Hasenclever GmbH + Co KG, Lüdenscheid, Germany, packs two to six modified compact shot nozzles of the Z3210 type into a minimum of space. According to the manufacturer, the modular design permits close cavity-to-cavity spacing and a flexible arrangement of the gates that would be unattainable with a conventional hot-runner solution and traditional multiple nozzle. The Multimodule can also be used individually like a central nozzle. The main advantages only become evident, however, in combination with a hot runner. In this configuration, it is easier to build multi-cavity molds thanks to the possibility of grouping cavities into clusters. The use of this module means there is no need for a complicated second runner level in the manifold block. A further advantage of this module is that it enables multi-point gating on one article. This saves cycle time and is of benefit with articles needing true-running accuracy.
The principle of the Multimodule provides the possibility of controlling all the gates individually and is extremely maintenance-friendly, because the modular design allows replacement of the nozzle tip, heater and heat sensor from the front. The position of the heating outlets is optional, making mold design and construction more flexible.
