Description

Plastic element manufacturing apparatus and method for Her ^¬ of the plastic member

FIELD OF THE INVENTION

The present invention relates to a plastic material element, in particular for a vehicle, and to a production device and a method for producing the synthetic material element.

TECHNICAL BACKGROUND

So far, body parts, as well as attachment to a Fahr ^¬ stuff are usually painted. Here, the surface sol ^¬ cher body paints, and the painted surfaces of resin-made mounting parts show, depending on the coating method on the surface of a distinct structural ^¬ structure, which is generally referred to as so-called. Cellulite.

Furthermore, from DE 10 2012 023 066 AI a foliende ^¬ decorated plastic molding known. Therein is shown a trim ^¬ aperture for a motor vehicle, which is made as an IMD molded part. The IMD molding is an art ^¬ material injection molded part, which has two differently designed De ^¬ korbereiche. In the first decorative area, for example, a shiny silver lacquer layer is applied, while in the second decorative area, the plastic material of the plastic ^¬ carrier is exposed on the visible side. At the transition between the two regions a decorative separation groove is incorporated in the plastic material of the plastic material ^¬ carrier, with which the two decorative regions are optically separated from each other. The art ^¬ material of the plastic substrate may be a black glossy substrate, in which the material, such as ABS-PC, or PMMA, is colored in accordance with an example. Such coated with a film trim strip has ever ^¬ but the disadvantage that their surface can be formed only as a smooth and homogeneous surface and is entspre ^¬ accordingly susceptible to scratches and dirt, etc., as they are immediately visible. Furthermore, the smooth and homogeneous surface of the trim strip forms a sichtba ^¬ ren and disturbing transition to a painted body part and is therefore only partially as an attachment to a vehicle, namely where a smooth and homogeneous surface, eg in a chrome-like trim strip is desired ,

DESCRIPTION OF EMBODIMENTS

In Fig. 1 is a perspective view of a flow of the Her ^¬ position a coated plastic element 1 according to an embodiment of the invention is shown schematically and highly simplified ^¬ fueled and not drawn to scale.

We previously described body parts, as well as attachment to a vehicle previously usually painted. The Oberflä ^¬ chen such body paintwork in a vehicle and the la ^¬ ckierten surfaces of plastic attachment parts show depending on the painting on the surface of a pronounced structure. In general parlance, this structure is referred to in professional circles as so-called orange peel.

Instead of painting, for example, add-on parts, such as panels or strips, roof beams, etc., an extruded attachment can be made in glossy black or even in the respective body color by means of a paint transfer film. In this case, the parts no longer need to be painted in an additional operation as before. Instead, the lacquer-like surface can be produced by a lacquer transfer film.

Due to the manufacturing method in which the paint film depending ^¬ stays awhile the paint transfer films by means of rollers or a doctor blade to be applied, this coating films each have ^¬ but on a smooth, very homogeneous surface. Therefore, a fixture provided with such a paint film and fitted to ei ^¬ nem vehicle, it is noticeable that versehe- with the paint film ne attachment to the rest of the painted environment of the vehicle due to its smooth surface. This results in an uneven appearance of the vehicle with undesirable transitions between the respective with ei ^¬ ner paint film coated attachment and each la ^¬ ckierten body part.

Therefore, a coated Kunststof ^¬ felement 1 according to the invention is prepared which is coated with a surface coating film 2 of a paint transfer film 3 and having a structured surface, said structured surface having game, a a painted surface ähnli possible ^¬ che structure or orange peel structure with ^¬.

Is ge ^¬ shows how in the present embodiment in Fig. 1, the plastic element 1 by means of an extruder is sion procedure made of a plastic material 14 completely as an extrusion part 23. In an alternative it ^¬ inventive embodiment, the plastic member may be only partially made as extrusion or extrusion with an additional base, such as in follow ^¬ FIG. 3 is shown. Here, for example, a Ba ^¬ sis, for example, a metal profile, provided in at least a portion, such as at its outer side or viewing side, with the extrusion onteil. For this purpose, the base is coated with the KunstStoffmate ^¬ rial 14 by the extrusion process in the at least one section.

The plastic material 14 consists of a plastic or a combination of at least two plastics. As a plastic, for example, polyurethane, and in particular a ^¬ sondere teilvernet ZTE polyurethane or a non-ther ^¬ mixed or possible slightly thermally deformable Po ^¬ lyurethan may be used. However, the invention is not limited to polyurethane as plastic. It can be any used in ^¬ particular plastic or combination of plastics, which are respectively suitable for making a plastic element 1 as extrusion and in particular arrival component of a vehicle which is coated with a paint film 2 of a paint transfer film. 3

The KunstStoffelement 1 can be designed as an attachment for a vehicle, for example as a panel or bar, roof rail or Wasserabweiser, manhole, Fahrzeugscheibeneinfas ^¬ solution, etc. ,.

In extrusion, the plastic material 14 is made of Wenig ^¬ least a melted plastic, for example melted continuously, and through a shaping nozzle 4 a

Extrusion device 5 discharged, as in Fig. 1 ver ^¬ simplified and not shown to scale. In this case, for example, a strip 6 or aperture is formed as a plastic element 1 by means of the shaping nozzle 4 as an attachment for a driving ^¬ convincing in Fig. 1.

In an alternative embodiment, as shown in subsequent ^¬ of Fig. 3, the KunstStoffelement 1 instead of completely made of the KunstStoffmaterial 14, for example, only partially made of the KunstStoffmaterial 14 who ^¬ the. For example, the plastic element may comprise a base, for example a metal profile of aluminum, an aluminum alloy or steel, etc., which is extrusion-coated in at least a portion with the plastic material 14 to form the plastic element as an extrusion with a base. Subsequently, the coated by extrusion with the plastic material portion of the Kunstele ^¬ ment is coated on its outside with a paint film of a paint transfer foil ^¬ to form the finished layered plastic fabric element. To form the plastic material coated with the portion of the plastic ^¬ felements having a defined surface structure and before the final application of the paint film, the

Plastic material to be mixed in more detail below described particles. The admixing of particles, for example ^¬, with reference to the embodiment in Fig. 1 and subsequent FIG. 2 described. In contrast to the Dar ^¬ position in Fig. 1, in which the plastic element 1 is fully ^¬ continuously formed as an extrusion member 23 is in the shown in the following FIG. 3 according to the invention exporting ^¬ approximate shape the base, for example a Metallprofilm, not shown, via a Base supply device supplied to the extrusion device and coated the base by means of the extrusion device with the plastic material. Next, the extrusion element is coated with the paint film and forms a textured surface by the admixed to the plastic material Parti ^¬ angle and / or by patterning with a manner described in more detail below patterning apparatus. The coating of the extrusion part with the paint film may immediately or at a late ^¬ ren time after leaving the extrusion apparatus in which the extrusion is formed, take place. For example, the coating of the extrusion can ^¬ SUC gene after a subsequent cooling bath for the extrusion. The invention is not limited to the examples mentioned at the time of Aufkaschierens the paint film to the Extrusi ^¬ onsteil. The paint film can be applied or laminated to the extrusion at any other suitable time. The same applies to a structuring of the paint film by a yet to be descriptive struc ^¬ rierungsvorrichtung. The paint film can by the Strukturie ^¬ tion device, such as a Narrolloller, a Besprenke- lling and / or spray nozzle device, directly or to be applied to the extrusion at a later time after leaving the extrusion device and patterned by the structuring device. Likewise, the paint film can also be applied to this after a subsequent cooling bath for the extrusion part and through the

Structuring device are structured. The struc ^¬ turing of the paint film can take place immediately after the application or lamination to the extrusion element in a subsequent downstream step.

In order to provide the plastic element 1 on its having a paint film to be coated outside with a a painted Oberflä ^¬ che similar structure as possible or orange skin structure, the plastic material 14 of the plastic element 1 are admixed, the particles mentioned above in accordance with an embodiment of the invention. The introduced in the plastic element 1 particles are not shown in Fig. 1 for reasons of About ^¬ sichtlichkeit.

The particles consist of a material or a material combination which ^¬ not or as little as possible in the melt plastic material or melts. Therefore, the particles form, as shown in the following Fig. 2, with the plastic material has a structured surface if it is additionally coated with the paint film 2, egg ^¬ ne orange peel or a painted surface forms mög ^¬ lichst similar structure.

In this embodiment for producing an orange peel structure or a structure on the extrudate or plastic fabric element 1 which is as similar as possible to a lacquered surface, the plastic or plastic material 14 below the lacquer foil 2 is replaced by at least one suitable additive in the form of particles which do not melt or melt only slightly modified. This particle additive produced in the plastic material has a surface structure which such transferred to the resist film 2 of the paint transfer film 3 after coating the Kunststof ^¬ felements 1 with this film 2 or maps, as is indicated in the following Fig. 2, so that a Oberflä ^¬ che similar the orange peel structure or the structure of a painted surface is generated. By the nature of the modifi ^¬ zierungsstoffes and the amount of addition, the structure of the extrudate or extrusion part and thus of the Kunststof ^¬ felements 1 can be specifically influenced.

The particles, for example, crosslinked particles and there ^¬ with non aufschmelzende particles of polyvinyl chloride (PVC) can be used or cross-linked rubber particles, wood particles, particles of at least one thermosetting material or thermosetting plastic such as epoxy resin, polyurethane, etc., particles of a mineral ^¬ metallic material, talc, chalk, glass, in particular Glasku ^¬ rules, ceramic, polyamide, metal, etc .. For instance, have a content in a range of 20% to 30% of particles of the plastic material. However, the invention is not limited to the sen ^¬ proportion in a range of 20% to 30% of particles. Depending on the function and intended use, the proportion may also be less than 20%. The particles can be made of the same material or at least two different materials, as well as the same size or

Diameter or at least two different sizes or diameters are mixed with the KunstStoffmaterial.

To mög ^¬ form the extrusion element 23 and plastic element 1 having a orange peel or a painted surface lichst similar structure, the particles, for example, have a diameter in a range of from 40pm to 60pm and preferably from 45pm to 55pm and particularly be ^¬ vorzugt of 50pm +/- 4pm on. Basically, the size or selected as desired the diameter of the particles, depending on ge ^¬ wünschter be manufactured embossing or structure of the Oberflä ^¬ surface of the extrusion 23 and the plastic element 1. Depending di ^¬ cker the paint film of the paint transfer film, the weaker and softer structure, or embossing the surface of the extrusion 23 or KunstStoff elements 1 shown. The thinner the lacquer transfer film, the stronger and sharper the structure or embossing of the surface of the extrusion part 23 or synthetic material element 1 is again imaged. The ent ^¬ speaking, by the choice of the size or diameter of the particles and the thickness of the paint film, the structure of the provided with the paint film surface of the extrusion 23 and the plastic member can be adjusted.

The expression e.g. The orange peel or the structure that is as similar as possible to a lacquered surface can be specifically influenced or adjusted by the choice of the diameter or the size of the particles. The larger the diameter or the size of the particles is selected, the coarser the surface of the extrusion part 23 or synthetic material element 1 provided with the paint film 2 and the smaller the diameter or size of the particles, the smoother is the one with the Paint film 2 provided surface of the extrusion part 23 and KunstStoffelements 1.

In the production of the extrusion 23 or ^¬ Kunststof felements 1 by extrusion of an extrusion apparatus 5 is used. As extrusion apparatus 5 while a Schne ^¬ screw extruder such as a single screw or a twin screw extruder, or a ram extruder can be USAGE ^¬ det. In the ram extruder by means of the pressure ei ^¬ nes piston is generated. Ram extruder are especially ^¬ is turned when the material to be processed can not be processed using screw extruders or a frequent pro- should be carried out. The invention is per ^¬ but not limited to the aforementioned examples of extrusion devices.

The running speed of the extrusion 23 or ^¬ art material elements 1 from the shaping nozzle 4 of the extrusion device 5 is preferably in a range of

10 ° m / min to 15 ° m / min. If a single-screw extruder is used as the extrusion device 5, the rotational speed of the extrusion screw of the single-screw extruder 5 is in a range of preferably 5 ° rpm to 25 ° rpm.

In the example shown in Fig. 1 embodiment 3, the paint transfer film in addition to the paint film 2, an optional Trä ^¬ carrier layer 11 and an optional additional layer of protection 24. The carrier layer 11 is arranged on the underside of the paint film 2 and the protective layer 24 on the upper side of the paint film 2. The carrier layer 11 is, before the coating of the later extrusion part before the extrusion ^¬ device 5 deducted from the paint film 2. The protective ^¬ layer 24, however, initially remains on the paint film 2 and, as shown in Fig. 1 is shown, for example, applied together with the coating film 2 on the extrusion portion 23 and only in a later step of the resist film 2 is removed to provide the finished with the paint film 2 beschich ^¬ teten plastic fabric element. 1

As shown in Fig. 1, the paint film 2 and, if present, the additional protective layer 24 of lacquer transfer ^¬ film 3 after the extrusion element 23 and plastic element 1, the shaping nozzle 4 of the extrusion device has leaving ^¬ sen 5, on a surface to be coated region of the is Extruded parts 23 and plastic fabric element 1 applied by a coating device 15. Preferably, the Paint film 2 and, if present, the additional protective layer 24 of the paint transfer film 3, for example, directly after leaving the forming nozzle 4 on the extrusion member 23 and the plastic ^¬ material element 1 introduced by the coating device ^¬ , as long as the extrusion member 23 and KunstStoffelement is still warm and Subsequently, the coated with the paint film 2 and, if present, additional protective layer 24 extrusion part 23 and KunstStoffelement 1 cooled. Here, the film with the varnish 2 and if any of the zusätz ^¬ union protection layer 24 or to cool the paint transfer film 3 coated extrusion element 23 and plastic element 1 at room temperature to be cooled by an additional cooling means not shown. The lacquer film 2 and, if present, the additional protective layer 24 can also be applied later to the extrusion part 23 or synthetic material element 1, for example before, during and, instead of being applied to the extrusion part 23 or plastic fabric element 1 directly after leaving the shaping nozzle 4 / or after the cooling of the extrusion 23 and the plastic member 1. While the coating film 2 on the extrusion portion 23 ver ^¬ remains for providing the finished plastic element 1, the protective layer 24, if present, is removed again from the Lackfo ^¬ lie 2 or subtracted. This can be done beispielswei ^¬ se at an extrusion with a metal base to a stretch bending process in which the the paint film 2 and the protective layer 24 coated extrusion was placed with its metal base in a desired shape by the stretching ^¬ bending process. However, the protective layer 24 can also be removed from the paint film 2 at any other suitable time.
