Definitions
- the invention relates to a method for providing texture on a product part. Such a method is known from practice.
- a pleasant appearance or a suitable roughness of the surface of a product there are used methods for providing texture thereon, which comprise providing patterns in relief on the relevant product, at least product part.
- patterns of depressions or differently shaped deformations of the surface of the relevant product part are provided, for instance, by means of mechanical or optical means. These deformations afford a texture.
- the deformations may be provided directly on a part of a consumer article but may, for instance, also be made in a die, such that when forming products in the relevant die, the desired structure is transferred to parts of products formed in the die.
- the object of the invention is to provide a method of the type described in the introduction, in which the above drawbacks are avoided, while retaining the advantages thereof.
- a method according to the present invention is characterized by the measures according to claim 1.
- the density of the deformations and the positions of the rows and/or columns of the relevant grids, at least of the deformations therein, can be displaced with respect to each other such that an at least visually slightly- random distribution of the deformations is obtained. Moreover, interference patterns can thus be prevented or, on the other hand, be stressed.
- the deformations of a first grid are at least partly overlapped by deformations of the second grid, which has the result that the random impression of the texture is further increased.
- a method according to the present invention is further characterized by the measures according to claim 3.
- a method according to the present invention is further characterized by the measures according to claim 5.
- a laser is preferably used to provide the deformations, which deformations are preferably point- shaped. It will be clear, however, that other methods may also be suitable for providing deformations, for instance mechanical operations, in which the deformations may additionally be differently shaped, for instance line- shaped.
- a method according to the present invention is further characterized by the measures according to claim 10.
- a texture according to the present invention on a forming tool, such as a die, a punch, a vacuum mold or the like, there is obtained the advantage that the resulting texture can be transferred to a large number of products in a very simple manner.
- a forming tool such as a die, a punch, a vacuum mold or the like
- the invention further relates to a product provided with a texture, characterized by the measures according to claim 13.
- the invention further relates the use of a laser for providing texture on a product part, characterized by the measures according to claim 16.
- the invention also relates to the use of a method for repairing texture, characterized by the measures according to claim 17.
- Fig. 1 diagrammatically shows a texture built up from two superimposed grids rotated with respect to each other
- Fig. 2 diagrammatically shows five grids rotated with respect to each other
- Figs. 3A-H show a number of examples of textures formed according to the invention, on a very large scale
- Fig. 4 shows a depression in cross-section.
- Figs. 1 and 2 there are used respectively two and five different symbols for indicating the different grids rotated with respect to each other. In practice, these grids will be built up from mutually equal, at least identically shaped, deformations of the same kind.
- Fig. 1 diagrammatically shows, on an enlarged scale, a surface 1 of a product, in top plan view, on which two grids 2, 4 are provided, which will be explained below in more detail.
- the product 1 is, for instance, a die cavity, in which products, such as consumer articles, chips, chips bars or the like can be produced, for instance by molding.
- the texture 10, 110 formed by the grids 2, 4 will be transferred to a corresponding part of the product to be formed.
- a first grid 2 is built up from rows R2 and columns K2, deformations of the surface 1, in particular depressions 6 in the surface 1, as, for instance, shown in Fig. 4 in cross- section.
- the depressions 6 in the first grid 2 are represented by squares.
- the depressions 6 are provided by means of a suitable laser and form the grid 2 in the form of a regular matrix.
- the depressions 6 have, in particular, a crater shape with a substantially circular cross-section in top plan view.
- the second grid 4 represented in Fig. 1 by triangles, also comprises, in a matrix comparable to that of the first grid 2, rows R4 and columns K4 of depressions 6, which are mainly equal to the depressions 6 in the first grid 2.
- the second grid 4 is rotated with respect to the first grid 2r through an angle ⁇ , in the embodiment shown, for instance, approximately 45°.
- ⁇ in the embodiment shown, for instance, approximately 45°.
- Fig. 2 shows a texture 10, built up from five grids, comparable to those shown in Fig. 1.
- a first grid 102 is represented in Fig. 2 by a matrix of squares.
- a second grid 104 represented by circles, a third grid 112, represented by octagons, a fourth grid 114, represented by triangles, and a fifth grid 116, represented by hexagons, are placed over it.
- Each of the grids 102, 104, 112, 114, 116 is built up from rows R and columns K of depressions 106, the depressions of all grids being the same. Only for the purpose of explanation, they are shown in the figure as differently shaped.
- the depressions 6 of different grids may also be of a different kind, for further adaptation of the texture 10, 110.
- the second grid 104 is rotated around a point C with respect to the first grid 102 through an angle 012.
- the third grid 112, the fourth grid 114, and the fifth grid 116 are rotated with respect to the first grid 102 around the point C through respectively a third angle 0C3, a fourth angle ⁇ , and a fifth angle 015.
- the first grid 102 defines a base angle ⁇ i, represented in Fig.
- Figs. 3A-H show a number of examples of textures manufactured on a steel surface suitable for injection molding of plastic.
- an Nd:YAG laser is used, while applying argon as protective gas.
- Table 1 gives a number of setting values for each of the examples shown.
- the examples as shown in Figs. 3A-F have been carried out according to Fig. 2
- the example as shown in Fig. 3G has been carried out as shown in Fig. 1, with an angle ⁇ of 90° and with a distance between the columns which is regular but deviates from the regular distance between the rows.
- the exemplary embodiment as shown in Fig. 3G is made with four grids rotated with respect to each other at regular angles. sample pulse RMS pulse spot size spacing laser focus mm degrees no. duration value fireq. micromicroconfiguration voltage above per step ms mv Hz meter meter cavity mm surface
- a texture according to the present invention is particularly suitable for being provided in a molding die or on, for instance, a punching or pressing tool, but can also be provided directly on a consumer article.
- the depressions of the different grids may advantageously all be identical, but it is also possible to provide different depressions for the different grids, to further influence the texture.
- the texture is provided circularly, it will be clear that any regular or irregular contour may be obtained for the texture, while such a texture may be provided both on flat and on single- or double-curved surfaces.
