- all these tools are technically difficult to manufacture, since a large number of individual parts have to be produced in a complex manner and then connected to one another in a very complex manner.
- the aim of the invention is to simplify the production of complex components in extrusion technology in such a way that manufacturing costs and production time of the components can be minimized, as well as a corresponding method.

- a melt cooler a spiral distributor, a combination of both or any other combination.
- Computer-aided manufacturing data is generated from the components designed with the aid of CAD, which are now used for the additive manufacturing of the components, similar to the production of parts using CNC machines.
- material is applied layer by material layer, creating a three-dimensional object.
- the solution with regard to the method is proposed, for the production of a component for an extrusion line, to design the component with computer support and to generate computer-aided manufacturing data therefrom in order to produce the component additively on the basis of this data, the component thus manufactured at least one of the following Functions fulfilled: even distribution of the melt over the fang, thermal homogenization of the melt over the circumference, mechanical homogenization over the circumference, cooling of the melt over the circumference.
- the component is structurally modified via computer-aided simulations until the extrusion process is optimized, before the computer-aided manufacturing data are generated.
- the flow behavior of the melt and / or the degree of homogenization of the melt and / or the residence time of the melt in corner areas of the component are advantageously examined in the simulation.
- Figure 1 shows a typical extrusion line
- FIG. 4 shows an alternative embodiment to FIG. 3
- FIG. 8 shows an enlarged detail from FIG. 6
- FIG. 9 shows an enlarged section of FIG. 7
- FIG. 10 shows the detail of FIG. 8 as a partial section
- FIG. 11 shows the detail of FIG. 6 in a further part
- FIG. 1 shows a typical extrusion line as it is used today for profile extrusion, regardless of whether it is for the production of window profiles or pipes. It shows an extruder 1 in which plastic is melted and continuously conveyed into the extrusion tool 2 for shaping. This is followed by a calibration and Cooling station 3 on Depending on the profile, additional cooling stations can be used. After the cooling stations, there is an extraction device 4. In order to cut the endless profiles 6 to the desired length, a separating device 5 is then arranged. The extrusion axis is marked with position number 7.
- FIG. 2 schematically shows a section through a component 8 according to the invention which is manufactured additively.
- the component 8 sitt a melt zekanal 17 on which extends from the melt inlet 14 to the melt outlet 20.
- the load-bearing element 13 is arranged in the component 8 on the mixing and cooling structure 16 and is thus held in the interior of the component 8.
- the connection point 15 is named here as a separate item number for the sake of clarity, due to the additive manufacturing process it is not a connection in the traditional sense, but is made in one piece.
- the melt is guided through the mixing and cooling structure 16, where it is thermally and mechanically homogenized and cooled.
- the mixing and cooling structure 16 has cooling channels 9 around which the melt flows.
- the cooling channels 9 have an inlet 10 and an outlet 11 via which the cooling medium flows from the outside of the component 8 through the cooling channels 9. Different media such as water, air or special coolants are used as the cooling medium.
- the component 8 can be combined with other components via the flange 12 at the end.
- the course of the section for the exemplary embodiments shown in FIGS. 3 and 4 is marked by the dash-dot line.
- FIG. 3 is a section through the schematic representation of the component 8 according to the sectional profile from FIG. 2.
- the first partial melt channel 18 extends from the melt inlet 14 over the melt channel 17 in the mixing and cooling structure 16 further via the second partial melt channel 19 to the melt outlet 20.
- the cooling channels 9 in the mixing and cooling structure 16 have an inlet 10 and an outlet 11 for a cooling medium.
- the extrusion axis is marked with position number 7.
- FIG. 4 shows an alternative embodiment of the mixing and cooling structure 16; here, too, the same components are identified by the same reference characters.
- Extrusion technology is a frequently used method in the processing of plastics. This is a continuous process in which, in addition to other products, plastic pipes are also manufactured.
- the dimensional and optical quality of the pipe essentially depends on the quality of the pipe tool.
- Current mechanically producible melt distributors, mixing or cooling components can have the desired Execute properties only conditionally or only separately.
- Static mixers are known from the prior art, so Wikipedia, for example, compares structure and mode of operation and design as well as advantages and disadvantages. Static mixers have some advantages over dynamic mixers, as they do not take up much space and are cost-effective due to their design.
- the Sulzer type mixer is listed here as having a very compact design, in which the handle blades cross or are designed with a large number of crosspieces arranged like a framework. However, this design has high pressure losses.
- Kenics mixer Wikipedia explains here: “It consists of sheet metal twisted by 180 °. Each helix is offset by 90 ° to the previous one and has the opposite direction of rotation. ”
- This Kenics mixer design is the basis of a further alternative embodiment of component 8 and is described in more detail in FIGS. 5-11. This embodiment is a further development of known static pipe extrusion melt distributors, in which a temperature control option is also integrated in the tool.
- FIG. 5 shows part of a section through the extrusion tool 2 along the extrusion axis 7, the melt channel extends from a first partial melt channel 18 via the component 8 according to the invention into the second partial melt channel 19 to the melt outlet 20.

- the individual areas are separated from one another by partition walls 25.
- position number 26 the direction of extrusion is denoted by position number 26.
- the component 8 is again shown, the partition walls 25, which separate the areas 22 and 23 from one another, being masked out here to clarify the twisted ribs 21.
- FIG. 8 shows an enlarged view A from FIG. 6; here, too, the twisted ribs 21 can be seen again, which are each arranged in the first area 22 and in the second area 23. As already described, the two areas are separated from one another by partition walls 25.
- FIG. 9 likewise shows an enlarged section B from FIG. 7, which shows the component 8 without the partition walls 25.
- the twisted ribs 21, which are arranged offset in the first region 22 with respect to the ribs 21 in the second region 23, can be clearly seen.
- the representation in accordance with FIG. 10 corresponds to the detail in accordance with FIG. 8, the component 8 being shown here cut open transversely to the extrusion direction 26. This sectional view shows that the ribs 21 have a cavity 24.
- FIG. 10a shows the sectioned component 8 and FIG. 10b shows an enlarged detail of this.
