Valve gate system

The special geometry of the hot runner minimizes pressure drops and optimizes color change New single nozzle screwed into the base for single valve gate injection; also suitable for polymers where the molding cycle phase is reduced. An Oerlikon HRSflow single nozzle system has the nozzle screwed directly into the tempered base to ensure the system has the required mechanical strength to deal with the thrust coming directly from the IMM barrel nozzle. The nozzles – heated by coil heaters – are specially-designed to achieve optimal control of both internal and injection point temperature. Internal duct geometry is specially designed to eliminate risk of material stagnation points and, as a result, favor color change and reduce the pressure drops in the system. Advantages Uniform temperature profile along the whole length of the nozzle High mechanical strength of the base. Specially designed geometry to minimize stagnation and pressure drops and optimize color change
