Cold runner system - FlowControl
In addition to the usage for article direct injection, the cold runner system FlowControl with its innovative shut-off nozzles is also very often utilized as universal cold runner for most different applications. Here DESMA is not exclusively focusing on the complete avoidance of runner waste, but also relies on the variable nozzle balancing. Since each nozzle has a separate hydraulic cylinder which actuates the sealing in conjunction with a mechanism arranged outside the nozzle. Due to this mechanism the compound runner is executed without disturbing nozzle which would result in high pressure drops. At the nozzle end only there is a slide nozzle with a needle end where the compound flows around.
