Fakuma 2021 New hot runner system for small injection moulded parts
Italy — At Fakuma 2021, Oerlikon HRS Flow will be presenting the new, particularly small hot runner systems of the S series with their low space requirement in the mould. The main field of application is the production of small-format technical components.
Depending on the application, HRS Flow's new S series can be equipped with screwed-in or non-screwed-in (face-to-face) nozzles. The inner bore size can be selected according to the shot weight. The design allows a compact mould structure with a minimum nozzle pitch of 37 mm. In the valve gate version, the S series is combined with either a compact cylinder 62 mm high or, in the version with adjustable needle position, with a 70 mm high cylinder. Internal laboratory tests have shown an optimal sealing and thermal profile along the whole nozzle. In addition, a special channel geometry enables fast colour changes.
The new S series is suitable for low shot weights, multi-cavity moulds and thin-walled components. Typical applications include consumer goods, technical and electronic components as well as small automotive parts such as emblems, interior switches, knobs for sound systems or air conditioning components.
At Fakuma, Oerlikon HRS Flow will showcase the application of the new S series for a so-called Hydration Reminder made of polypropylene (PP). Attached to bottles or glasses, it reminds the user by signal to drink regularly. The S series made it possible to meet the requirements for a low part weight with a wall thickness of only 1 mm as well as for quick colour changes.
