HASCO launched the single needle valve gate nozzle SNV-06, SNV-12, with the corresponding melt deflection, as a ready-to-install, all-in-one unit with either hydraulic or pneumatic drive. The use of standardised components and interchangeable parts, as well as the identical fitting space required for the hydraulic and pneumatic versions, make the unit particularly service-friendly.
The single needle valve gate nozzle includes a flanged-on nozzle and is designed for use with nozzles of the TechniShot Z33/… series. Needle diameters of 2mm to 6mm and needle strokes of 8mm to 12mm ensure low pressure losses. Melt guidance similar to that in multi-cavity distributor systems means that results achieved with a single-cavity mould can be directly transposed to multi-cavity applications. The new heating concept with improved temperature distribution opens up a wider field of application for engineering plastics too. A uniform temperature profile is always ensured right through to the gate.
