-To create, load, edit and save a die choose the respective command within the main menu under configuration. The window die configuration (see figure) comes up when choosing create or edit die.+In addition, a created tool can be saved there. **Load tool** calls up a previously saved tool. The menu item //Create tool...// opens the tool configuration.

   * **Filter element:** In order to calculate the pressure loss with a filter the filter area, the mesh size and the number of filter elements as well as different reference parameters (known from practical tests) have to be indicated. This involves the pressure decrease which was measured with a reference melt flow rate and a reference melt temperature. The reference values and the pressure decrease that has to be calculated to a constant mesh size.   * **Filter element:** In order to calculate the pressure loss with a filter the filter area, the mesh size and the number of filter elements as well as different reference parameters (known from practical tests) have to be indicated.

-All die segments are defined one after another, beginning with the part at the screw tip and ending with the die gap. The **Up** and **Down** buttons change the position of the single elements. They also allow the definition of an element between already defined geometries. To delete a part of the die mark it first and then choose **Delete**. When hitting **Ok** the die is added to the configuration. To save the die separately choose **configuration**, **save die** or save it via saving the complete process (cf. chapter Create a Process).+All tool segments are defined one after the other by inserting the corresponding geometry, entering all data and inserting the next geometry. It should be noted that the tool is constructed from the screw tip to the tool exit. The order of the tool segments can be changed as desired using the //Position forward// and //Position back// buttons. In this way, it is also possible to define a part of the tool that must be inserted between two already defined geometries.
  
-Alternatively to a given pressure at the screw tip the dialog **Process parameters** offers the possibility of calculating the pressure drop of the die when checking the box.+The //Delete// button deletes the selected part of the tool structure.
  
-**Path:** Configuration > Save die as...+The //OK// button completes the tool structure and returns you to the process.
  
-===== Graphic Depiction of the Results =====+The tool must then be saved. This is done via the menu item:
  
-If a tool is used the user can also view the shear rate and the pressure in the tool. With the menu item //shear rate in graphic// the user gets to the diagram. Unlike in the previous diagrams the process is sketched by the tool. If the user moves the mouse over the individual tool element more information about the tool element are shown in the properties window.+//Configuration > Save tool as...// 
 + 
 +Further details about the calculation of dies is given in the reference manual (s. [[en:grundlagenhandbuch:werkzeug:grossflaechenschmelzefilter#die|die]]). 
 + 
 +**Graphical representation of the results** 
 + 
 +When a tool is used, the user can also display the shear rate and pressure in the tool. The user can access the diagram via the menu item //Shear speed in graph//. Unlike in the previous diagrams, the curve is now drawn over the tool. If the user moves the mouse over the respective tool elements, further information about the tool element is displayed in the properties window.

-The triangle beneath the diagram symbolizes the screw tip. A rectangular element is depicted by a conventional rectangle, a tube element is depicted by a rectangle with a dashed curve. Annular elements are depicted by a rectangular with a dashed stripe in the center and all conically shaped elements are depicted by the changing diameter. A filter element is depicted by a twice dashed area.+The triangle drawn below the diagram symbolises the scroll tip. While a rectangular gap is represented by a conventional rectangle, a rectangle with a dashed line illustrates a circular cross-section. Ring gaps are indicated by a rectangle with hatched stripes in the middle, and all conical elements are represented by the changing diameter. A filter medium is described by a double-hatched area. 
 + 
 +===== Tube Element ===== 
 + 
 +For the die element tube element length and diameter have to be indicated in mm. The amount indicates how many parallel elements exist in the die. 
 + 
 +{{ :en:eingabe_der_maschinenparameter_und_konfiguration:werkzeug:en_sigma150_dlg_eingabe_der_maschinenparameter_und_konfiguration_werkzeug_002.png?nolink |}} 
 + 
 +===== Conically shaped Tube Element ===== 
 + 
 +Similarly to the geometry of the tube element again length and diameter have to be indicated. The diameters should vary with the conically-shaped tube element. Therefore they are indicated in the dialogue fields diameter inlet (D) and diameter to the outlet (d). The amount indicates how many parallel elements exist in the die. 
 +

 + 
 +===== Rectangular Element ===== 
 + 
 +This element is defined by the sizes length, height and width. The amount defines how many parallel elements exist in the die. 
 + 
 +{{ :en:eingabe_der_maschinenparameter_und_konfiguration:werkzeug:en_sigma150_dlg_eingabe_der_maschinenparameter_und_konfiguration_werkzeug_004.png?nolink |}} 
 + 
 +===== Conically shaped Rectangular Element ===== 
 + 
 +In this dialogue length and width for each the inlet and the outlet have to be indicated. Again the length of the die and the amount of parallel elements has to be indicated. 
 + 
 +{{ :en:eingabe_der_maschinenparameter_und_konfiguration:werkzeug:en_sigma150_dlg_eingabe_der_maschinenparameter_und_konfiguration_werkzeug_005.png?nolink |}} 
 + 
 +===== Annular Element ===== 
 + 
 +This geometry needs an internal and an external diameter. The length and the amount of parallel elements have to be indicated, too. 
 + 
 +{{ :en:eingabe_der_maschinenparameter_und_konfiguration:werkzeug:en_sigma150_dlg_eingabe_der_maschinenparameter_und_konfiguration_werkzeug_006.png?nolink |}} 
 + 
 +===== Conically shaped Annular Element ===== 
 + 
 +Like with all conically-shaped geometries the internal and the external diameter for the inlet and the outlet have to be indicated separately. The indication of length and the amount of parallel elements is also necessary. 
 + 
 +{{ :en:eingabe_der_maschinenparameter_und_konfiguration:werkzeug:en_sigma150_dlg_eingabe_der_maschinenparameter_und_konfiguration_werkzeug_007.png?nolink |}} 
 + 
 +===== Filter Element ===== 
 + 
 +In order to calculate the pressure loss with a filter the filter area, the mesh size, the amount of elements and different reference parameters have to be indicated. The latter are known from practical tests. These are the decrease in pressure which was measured at a reference mass flow and a reference mass temperature. The reference values as well as the decrease in pressure to be calculated refer to a constant mesh size.

 +Futher details about the calculation of filter elements is given in the reference manual (s. [[en:grundlagenhandbuch:werkzeug:grossflaechenschmelzefilter#large-area_melt_filter|Large-area Melt Filter]]).
