HRS Flow Servo-controlled valve gate systems
Introduced in early 2020, Flexflow Evo is an advancement of the Flexflow technology for servo-electrically driven valve gate systems from HRS Flow.
With actuators directly fixed on the manifold, the result is a ready-to-install system for quick and safe installation on the mould. The updated software simplifies the operator’s work and can be easily retrofitted to all existing control units, according to the company.
Flexflow Evo is complemented by the Flexflow Evo One valve gate system, which is also servo-motor driven. Instead of the usual control system, a simply designed driver module coupled to each individual nozzle takes over the task of controlling the melt flow in order to produce molded parts with reproducibly high quality.
Currently, the most promising application trends for the Flexflow Evo technology include family moulds and back-injection of films. Companies using family moulds for the simultaneous production of different parts in a single shot benefit from cost savings compared to separate production of the individual components.
