Single-Shot Nozzle Guarantees Efficient Injection Temperature Control

The Single Shot H6300 from Hasco offers an optimal price-to-performance ratio in the field of single nozzles and features improved temperature control. The range, extended with hardened nozzle tips, as well as single-hole and hot tip torpedo options — which are also used with the Vario Shot — increases this nozzle’s application possibilities.

The Single Shot comes in two sizes and is suitable for the production of small- and medium-sized injection molding with a shot weight of up to 800 g and immersion depths of more than 170 mm.

The interchangeability of the relevant wear parts, including tips, melt chambers and the thermocouple, facilitates servicing and maintenance. The heating unit, which is connected to the body of the nozzle with only one control circuit, is said to guarantee 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 mold filling are ensured. Through the optimized position of the thermocouple and the efficient insulation from the mold, plastics with a more limited temperature range can also be reliably processed.

When developing this nozzle, Hasco aimed to achieve the largest possible melt throughput plus a compact design and maximum stability. Its construction, with only one control circuit, reduces the time required for design. The energy requirement for the Single Shot during use is reported to be particularly low.

Even with the Single Shot nozzle, 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 gate quality. Extended melt chambers are available for gates to free-form surfaces or sub-runners with a sprue.
