28 smart_molding international 2/2023 molds and tooling T he Single Shot H6300/... offers the best price-to-performance ratio in the field of single nozzles and boasts optimum temperature con- trol. The extension to the range with hardened nozzle tips and Single-hole and Hot Tip Torpedo – as are also used with the Vario Shot – increases the application possibilities of this nozzle many times over. The Single Shot comes in two sizes and is suitable for the production of small and medium-sized injection mouldings with a shot weight of up to 800 g and immersion depths of over 170 mm. Maximum flexibility The interchangeability of the relevant wear parts, including tips and melt chambers and also the thermocouple, facilitates servicing and maintenance. The heating unit, which is connected to the body of the nozzle with just one control circuit, guarantees a uniform temperature over the full length of the nozzle. Because of the suitably adapted heating-capacity distribution and the gentle conveyance of the melt through generously-dimensioned flow channels, a homogeneous temperature profile and low-shear mould filling are ensured. Through the optimised position of the thermocouple and the efficient insulation from the mould, plastics with a more limited temperature range can also be reliably processed. Compact design The aims pursued when developing the nozzle were to achieve the largest possible melt throughput plus a compact design andmaximum stability. The construction with only one control circuit reduces the time required for design. In connection with the focus on good insulation from the mould, the energy requirement for the Single Shot during use is particularly low. Best price-to-performance ratio The Single Shot nozzle offers the best price-to-performance ratio in the field of single nozzles, but users do not have to dispense with a variety of injection options. A range of torpedoes and screw-on melt chamber variants are, for example, available. In addition to the classical pin gate, these also permit the nozzle geometry to be readily introduced into the cavity plate and, in the event of wear, allow rapid restoration of the gate quality. Extended melt chambers are available for gates to free-form surfaces or sub- runners with a sprue.
