In addition to all standard plastics, the new Single Shot nozzles can process technical and slightly reinforced materials, as well.
Hasco Hasenclever GmbH + Co KG of Lüdenscheid, Germany, has expanded its portfolio of nozzles with the Single Shot series of nozzles. Their development concentrated on compatible installation dimensions, precise temperature control, functionality, as well as cost-effective design. The wide variety of nozzle versions enables simple gating to sub-manifolds and direct connections to the molding.
High-end solutions are not always required. For many applications, a purposeful and uncomplicated nozzle is quite sufficient. In addition to all standard plastics, the new Single Shot nozzles can process technical and slightly reinforced materials, as well. They are available for processors in two sizes and can be used to produce small and mid-size injection molded parts with shot weights of up to 800 g, as well as immersion depths as much as 179 mm.
Simplified Maintenance and Repair Work
Relevant wear parts, such as tips and pre-chambers, even the temperature sensor can be exchanged if required, thereby simplifying maintenance and repair work. The single-loop heater is pressure-grouted directly on the nozzle body to ensure uniform temperature over the entire length of the nozzle. The adapted heating power distribution and the material-saving melt flow through generously dimensioned flow channels ensure a homogeneous temperature curve and low-shear part filling. Even plastics with narrow temperature windows can be reliably processed due to the efficient arrangement of the Fe-Con thermocouple and insulation against the cold mold.
Maximum mass throughput together will compact design and high stability were the goals for designing the nozzle. The single-loop version is suitable for small installation spaces, and the grouted heater has a very low energy requirement overall. For tuning the nozzles and nozzle tips to the specific case of application, Hasco provides customer support by the hot runner supplier’s specialist consultants and application engineers.
