Optimization of the component behavior using runner modification
Detailed diagnostics of the flow behavior
By slightly modifying the runner the fill operations can be controlled, influenced and a regular flow behavior can be achieved. Non-uniform behavior of the flow inside the cavity but also between the individual cavities can be efficiently optimized and scrap rates and cycle times reduced whilst ensuring higher productivity.
Factors influencing the flow behaviour
The viscosity of the polymers is affected by the shear rate and temperature. By increasing the shear rate, the viscosity decreases. Any increase in temperature reduces the viscosity. The highest shear rate is directly beside the frozen surface layer. The shear viscosity and the shear heating reduce the viscosity in this area.
The MeltFlipper technology is used very successfully in all conventional injection molding manufacturing processes, single or multiple cavities, cold or hot runner systems.
