Hot Runners Target Small Applications
Oerlikon HRSflow’s new S Series Nozzles can run engineering plastics and offer a compact product with a reduced pitch.
Oerlikon HRSflow launched the new patent-pending hot runner system series for small applications in late 2021. Depending on the application, the new line can be equipped with Sa, Tp and Sp nozzles. The Sa series is a screwed-in hot runner system, while the Tp and Sp series are face-to-face products with different inner bore sizes. The technology will be on display at the PTXPO (March 29-31; Donald E. Stephens Convention Center; Rosemont, Ill.)
Designed for injection molding of technical and electronic components, the Sa Series offers a compact hot runner for the production of such automotive parts as exterior emblems, small interior switches, sound system knobs or tiny components in air-conditioning systems.
The TP and SP series are well suited for multi-cavity applications weighing up to 30 g. In the Thermal Gate version, the minimum nozzle spacing is 29 mm and 22 mm, respectively. Oerlikon HRSflow says laboratory research into heat distribution showed that the new series provided optimum sealing and a consistent temperature profile along the entire nozzle. In addition, the optimization of the channel geometry reportedly enables fast color changes.
In the valve gate version, the series is equipped with a compact cylinder. In its basic version, the cylinder has a height of 62 mm, while in the adjustable version, which allows for optimal positioning of the pin, the height is 70 mm.
