In early 2021, Oerlikon HRSflow has launched a new patent-pending hot runner system series for small applications. This Series is mainly suitable for engineering plastics and offers a compact solution for a reduced pitch. Based on extensive laboratory research into heat distribution, the new Line ensures optimum sealing with an optimal temperature profile along the entire nozzle. In addition, the optimisation of the channel geometry enables fast colour changes. Picture by courtesy of Tecos.

With HRScool Evo, Oerlikon HRSflow presents a further development of the HRScool hydraulic cylinder system for hot runner injection moulding, which, thanks to its sophisticated temperature management, does not require active liquid cooling of the actuation unit. 

Oerlikon HRSflow has developed a Mechanical Stroke Regulator (MSR) for hydraulic driven valve gate systems that makes it easy to individually preset the opening positions of the pins in hot runner systems. Via a graduate scale adjusting screw the user specifies the individual oil volume, which the valve gate system then uses to bring the needles into the intended positions.
