The new FLEXflow Accurate, stable and easytouse ServoDriven valve gate for top quality.
The new FLEXflow The turn key solution for your top quality applications The New FLEXflow is a ServoDriven valve gate that assures accurate, easy and flexible control of pressures and flow rates during the whole injection process. It is a step forward in the sequential injection molding thanks to its high flexibility in adjusting the process parameters. The new ServoDriven valve gate is designed to independently control each valve pin by precisely adjusting position, acceleration, velocity and stroke. Among the various benefits, FLEXflow allows to improve parts quality and perform the most challenging applications. OPERATING PRINCIPLES Flexible and accurate valve pin control Filling phase: accurate pressure and flow rate control Holding phase: reduction of peak pressure and more even pressure distribution Pressure [bar] 900 800 700 600 500 400 300 200 100 Standard Cascade Molding Smooth Opening Cascade with FLEXflow 0 0 0.5 1 1.5 2 2.5 3 3.5 4 Time [s] Valve pins management during the injection cycle Pin position (%) 100 75 FILLING HOLDING COOLING Flow rate adjustment Pressure balancing 50 25 0 5 10 15 20 25 30 t (s) MAIN ADVANTAGES AESTHETICAL RESULTS Surface quality improvements: Class A large surfaces, grained surfaces, aesthetical parts Warpage reduction Optimal flow balancing Pressure Line COST SAVINGS Clamping force reduction around 20% Part weight reduction up to 5% High process repeatability Tool bending reduction = low stress solution 3500t 2800t
