-======Input of a die characteristic (REX) ======
-In REX Next Generation, the tool characteristic curve option (accessed via the menu //Configuration// > //Tool configuration// > //create new// > //Characteristic curve//) allows you to simulate the pressure throughput behaviour of a tool. This function is particularly useful for modelling and predicting the performance of a tool under real conditions.
-=====Definition of the operating point=====
-{{ :eingabe_eines_werkzeugs:rex171_werkzeug_en_009.png?nolink |}}
-In order to carry out the simulation correctly, the data of a real operating point must be entered into the mould configuration. This operating point forms the basis for the calculations and is characterised by the following parameters:
-  *     **Mass throughput**: The actual material flow that is conveyed through the mould.
-  *     **Tool back pressure**: The pressure that is applied to the tool and influences the material flow.
-  *     **Measured melt temperature**: The temperature of the material recorded at this operating point.
-As an operating point can only ever be run with a specific material, a material must be defined in the process before the simulation to ensure that the simulation is carried out consistently with the real conditions.
-====Determination of the conductance====
-After entering the operating data mentioned above, the conductance of the mould is determined. The conductance is a characteristic value for the respective tool and describes the pressure-throughput behaviour as a function of the process conditions.
-====Calculation of pressure and mass throughput====
-By combining the process parameters of the screw and the conductance of the mould, REX can calculate the pressure at the tip of the screw and the conveyable mass throughput.
