Definitions

  • the present invention relates to a method of partial metallization of a plastic part. It relates for example, but without limitation to the object and scope of the present invention, a method of partial metallization of a lighting and / or vehicle signaling mask, in particular of a motor vehicle . Finally, it relates to a lighting and / or vehicle signaling light mask, in particular a motor vehicle, which is obtained by such a method.
  • Lighting and / or signaling lamps for motor vehicles include, for example, position, passing and road lights, direction-change lamps, supplemental "long-life" lamps, fog lamps , daytime running lights, etc. They all include at least one light source, a reflector, and an outer ice.
  • This outer ice is generally smooth and translucent, the trend is to metallize interiors of devices.
  • Metallization is a surface treatment that gives a glossy reflectivity to an opaque material. It consists in depositing a thin layer of a metallic material, such as aluminum for example.
  • the document FR 2 719 604 describes such a metallization process for plastic parts, in particular made of polycarbonate.
  • the use of alkaline products is reduced to a minimum during metallization operations.
  • the final step uses an electrolytic or chemical deposition process operating in a strongly acidic bath.
  • it eliminates any deposit of money that would require the use of a cyanide bath. This avoids the appearance of hydrolysis of the polycarbonate leading to tearing of the metallization and the appearance of blisters on the paint possibly covering this metallization.
  • the object of the present invention is to achieve a metallization of the part to be treated which is partial.
  • partial metallization means the removal of a metallization on a well-defined area of the part, and not on the entire outer surface of the part.
  • Another object of the present invention is to provide such a method of partial metallization of a plastic part, in particular of a lighting fire and / or motor vehicle signaling mask, which is of simple design, easy to implement, which is precise, reliable and economical.
  • the present invention relates to a partial metallization process of a plastic part, which consists of spraying a metallic material on a defined area of the part and which comprises the following steps:
  • a notch is made on the whole contour line delimiting said delimited zone, the notch having a definite section and creating on the part a peripheral technical zone of said delimited zone, and
  • the section of the notch forming said peripheral technical zone is a recessed section in "V" which cooperates in form concordance with the section of the front end portion of the metallization tool.
  • the metallization tool preferably has a "bell” shape, the open front end portion of the "bell” shape being intended to fit on the peripheral technical zone of the piece to be metallized. .
  • the angle of the "V" is different at the top and bottom of the peripheral technical area, and therefore the angle of the "V" of the corresponding section of the front end portion of the Metallizing tool is different at the top and bottom.
  • the angle of the "V" may be, for example, of the order of 40 ° at the top and 50 ° at the bottom.
  • the metallic material of the metallization may be, for example, aluminum.
  • the subject of the invention is also a lighting and / or vehicle signaling light mask, in particular of a lighting and / or signaling light of a motor vehicle, which is partially metallized, this partial metallization being obtained according to the invention. method described above in outline.
  • FIG. 1 is a perspective view of a motor vehicle lighting fire mask, with a well-defined metallized zone
  • FIG. 2 is a schematic representation of the means for delimiting the zone to be metallized on the piece in treatment, according to the present invention
  • FIG. 3 is a diagrammatic representation of the principle of the partial metallization process, according to the present invention
  • FIGS. 4 and 5 schematically represent the spraying tool for the metallization material approaching the zone to be metallize (figure
  • the part to be metallized is a motor vehicle lighting light mask, of general reference 1, obtained by molding a plastic material, for example a material of ABS type (acrylonitrile and styrene copolymer).
  • a plastic material for example a material of ABS type (acrylonitrile and styrene copolymer).
