Needle Valve

With its Z10710/ universal needle valve unit, HASCO (Arden, NC) has created an amazingly simple solution addressing the following problems: splitting of the melt that produces weld lines on flat surfaces; limited choice of nozzle lengths and diameters; impossibility of directly transferring results from single-cavity development molds to their multi-cavity counterparts because nozzle types vary and size of conventional single shot needle valve systems result in a large overall installation height demanding larger mold configurations.

With its Z10710/ universal needle valve unit, HASCO (Arden, NC) has created an amazingly simple solution addressing the following problems: splitting of the melt that produces weld lines on flat surfaces; limited choice of nozzle lengths and diameters; impossibility of directly transferring results from single-cavity development molds to their multi-cavity counterparts because nozzle types vary and size of conventional single shot needle valve systems result in a large overall installation height demanding larger mold configurations. The basic concept for Hasco’s needle valve system is focused on a universal and modular design. The needle drive unit is available in two standard sizes and can be combined with all HASCO Techni Shot and Valve Shot nozzles, which offers a wide choice of nozzle type and size, allowing runner diameters and nozzle lengths (up to 300mm) to be optimized, as well as flexibility in the design of the needle guide and gating solutions. The system is extremely compact and can be easily integrated into small molds with reduced build height. Another major advantage of the Z10710/ is that the unit can be used either as a single nozzle centrally mounted in the middle of the mold or as a drive unit mounted between the manifold and nozzle.
