In early 2021, Oerlikon HRSflow has launched a new patent-pending hot runner system series for small applications. This S-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 S series 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.

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. 

Entirely designed according to the lean manufacturing criteria, the new workspace completes the project with which the company has brought a reappraisal and a re-design for the hot runners' assembly process. The goal is to guarantee an increase in the production capacity and more flexibility for the clients of the European market.

The Stihl Inc. manufacturing plant in Virginia Beach, Va., was experiencing cosmetic issues with the injection molding of a curved chainsaw handle. How did the Company solve the problem? It switched from a pneumatic valve gate to FLEXflow Evo: our servo driven valve gate system.
