Definitions
- the present invention relates to an article obtained by multiple injection of ceramics and/or cermets. It relates more particularly to a horological component such as a bezel produced by injection of ceramics and/or cermets of different colors.
- the object of the present invention is to overcome the aforementioned disadvantages by proposing a new multi-material injection process limiting the differences in shrinkage between the distinct materials injected.
- the present invention relates to a manufacturing method making use, during the injection step, of an insert having a raised or recessed structure intended to imprint on the first injected material a gripping surface for the second material injected.
- This gripping surface makes it possible to maintain the second material injected, to reduce the shrinkage during the sintering step and to avoid the separation of the two materials during the machining step.
- the method further comprises a machining step before and/or after the sintering step to respectively size the green body and/or the blank and to partially remove the second material so as to reveal the first material.
- the present invention also relates to the ceramic and/or cermet article resulting from the manufacturing process.
- the article according to the invention comprises at least two distinct materials differing by their colors, more generally by their aesthetic appearance, and/or their mechanical properties.
- the article comprises a part where the two materials are interleaved.
- the article comprises a part where one of the materials fills indentations made in the other material.
- the present invention relates to a manufacturing process by injection of an article made with at least two distinct materials which are either a cermet or a ceramic.
- the term “separate materials” means materials that differ by their aesthetic appearance, in particular their color, and/or by their mechanical properties. This results in differences in chemical compositions. It can be the same base material with different pigments to change the color or different base materials. By way of example, it may be the same base material based on zirconium oxide with, on the one hand, a black pigment to obtain a black material and, on the other hand, alumina to obtain the white color. More generally, the ceramics can be nitrides, carbides and/or oxides.
- cermets may comprise a ceramic phase comprising carbides, nitrides and/or oxides and a phase of a metallic binder chosen, for example, from precious elements such as ruthenium, rhodium, palladium, osmium, iridium, platinum, gold and silver.
- the article according to the invention can be a decorative article such as a constituent element of watches, jewellery, bracelets, etc.
- this article can be a trim component such as a middle part, a back, a bezel, a pusher, a bracelet link, a dial, a hand, a dial index, etc. It can also be a component of the movement such as an oscillating weight, a plate, etc.
- the article is a bezel 1 made with two ceramics 2 and 3 of different colors, for example black and white, with one color which occupies a quarter of the circle of the bezel and another color which occupies three remaining quarters of the circle as shown in figure 6 .
- the article comprises a part 4 where the two materials 2 and 3 overlap and more specifically overlap ( fig.5B ).
- Interlocking is understood to mean that one of the two materials has on its surface a structure filled by the other material.
- the two materials 2 and 3 are observed which are superimposed with the nesting of one in the recesses 2a formed on the surface of the other.
- the article is made by injecting different materials to form a green body and by sintering said green body.
- the manufacturing process is illustrated below for an article comprising two distinct materials, but it could be an article comprising 3, 4, etc. different materials with production of a gripping surface for each of the successive materials injected.
- the method further comprises a machining step preferably carried out on the green body before sintering so that the material is not too hard. During this machining step, the second material is at least partially removed in order to reveal the first material.
- the present invention does not exclude that the machining step is carried out partly before sintering and partly after sintering.
- the method may optionally include a debinding step before the sintering step if the materials have been injected with a system of organic binders (paraffin, polyethylene, etc.).
- a debinding step before the sintering step if the materials have been injected with a system of organic binders (paraffin, polyethylene, etc.).
- the injection device comprises a mold 5 with a fixed part 5a formed of two cavities 6 with a first cavity 6a intended for the injection of the first material 2 and a second cavity 6b intended for the injection of the second matter 3 ( fig.1 ).
- the first imprint 6a comprises the insert 7 with the structure in relief.
- the insert is attached to the cavity but it could also be integral with the rest of the cavity.
- the first material 2 is injected into the mold 5 formed of the fixed part 5a and the movable part 5b as shown in picture 3 to the right. Then, the mobile part 5a with the first injected material 2 is moved above the fixed part 5b of the other cavity 6b to perform the injection of the second material 3 ( fig.3 to the left).
- the insert 7 with a structure in relief is intended to print hollows 2a in the first material 2 which will serve as a grip during the injection of the second material 3.
- the insert 7 protrudes with respect to the plane of the cavity 6a so as to form a pocket 9 which will be filled with the second material 3 during the second injection ( fig.3 to the left).
- the figure 4 represents the green body 8 resulting from the bi-injection with the second material 3 superimposed on the first material 2.
- the carrot 10 is cut and the inside diameter of the bezel is hollowed out.
- the layer of second material 3 is removed with the exception of the layer filling the pocket so as to obtain the blank of the figure 5A .
- the manufacturing process includes a finishing step which consists in polishing the surface of the sintered blank and etching the surface if necessary, with for example indexes 12 in the case of a bezel 1 ( fig.6 ).
- a bezel 1 according to the figure 6 is obtained by injection of a white zirconia and a black zirconia and by sintering at a temperature of 1400° C. for a time of 48 hours under an oxidizing atmosphere.
