In booth 2217 in hall A2, Oerlikon HRSflow will present the new S series hot-runner systems, which require minimal space in the mold. The main field of application is the production of small-format technical components.
The new S series hot runners can be equipped with screw-in or face-to-face nozzles. The inner bore size can be selected according to the shot weight. The design allows a compact mold structure with a minimum nozzle pitch of 37 mm. In the valve gate version, the S series is combined with either a compact 62-mm-high cylinder or, in the version with adjustable needle position, a 70-mm-high cylinder. Extensive internal lab tests ensure an optimal sealing and thermal profile along the whole nozzle. In addition, special channel geometry enables fast color changes.
The new S series is suitable for low shot weights, multi-cavity molds and thin-walled components. Typical applications include consumer goods, technical and electronic components, and small automotive parts such as emblems, interior switches, knobs for sound systems or air conditioning components.
At Fakuma, Oerlikon HRSflow will demo an application of the S series involving a "hydration reminder" made of polypropylene. Attached to bottles or glasses, it reminds the user 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 color changes.
