Definitions

  • the present invention relates to a method of manufacturing a colored piece of material thermoplastic, with a finished appearance metallized, according to which said part is molded by injection of a colored thermoplastic material.
  • the invention also relates to a colored piece made by injecting a thermoplastic material colored, with a metallic finish appearance.
  • the invention finds a particularly application advantageous for the production of vehicle hubcaps automobiles and in particular a wheel cover motor vehicle.
  • gray polyamide is a material first more expensive than gray polypropylene, this one is most often used in this type of process.
  • the present invention provides a new method of manufacturing a such piece, characterized in that after the step of molding, is applied to said colored molded part, a protective varnish that incorporates mother-of-pearl glitter giving said piece the metallic finish appearance wish.
  • the metallized appearance is given according to the conforming process to the invention by the varnish itself, this varnish being a special varnish including a base of usual varnish in which has been incorporated mother-of-pearl flakes for return the desired metallic finish to the room out of production.
  • the method according to the invention has the advantage in in addition to eliminating the use of said metallized base which is an expensive material, to use a single cabin paint for the application of protective varnish, unlike the already known methods which use two paint booths for base application metallized and the application of protective varnish.
  • the process according to the present invention is a shorter process which increases production rates (i.e. the number of parts per hour manufactured) and thereby reduce production costs of these parts.
  • the removal metallized base contributes to cost reduction of production of said parts.
  • the molding of the part of color is made with polypropylene including a 20% charge of tinted talc.
  • polypropylene allows further reduce production costs compared to process already known, using polyamide.
  • a protective varnish comprising 2 % by mass of mother-of-pearl flakes with a diameter included approximately between 50 and 150 ⁇ m.
  • This protective varnish glitter is based on polyurethane.
  • the present invention also relates to a piece of color produced by injecting a material colored thermoplastic, with a finished appearance metallized, characterized in that it is coated with a protective varnish that incorporates mother-of-pearl glitter giving said piece the appearance of a finished metal metallic desired.
  • a part is made using of polypropylene loaded with tinted talc.
  • the varnish of protection constituting the external coating of this part can be polyurethane-based and includes mother of pearl flakes with a diameter of approximately between 50 and 150 ⁇ m.
  • such a colored piece constitutes a wheel cover for a motor vehicle wheel.
  • the process according to the present invention is a process for manufacturing a colored piece of material thermoplastic, with a finished appearance metallized, such as for example, a wheel cover motor vehicle which in the majority of cases, has a metallic gray appearance.
  • This manufacturing process includes a first step consisting in molding said part by injection of a colored thermoplastic, such as polypropylene loaded with 20% tinted talc.
  • a colored thermoplastic such as polypropylene loaded with 20% tinted talc.
  • the blank is intended to be covered with a metallized base comprising a gray coloring that gives the room in addition to the desired metallic finish, color final.
  • the blank leaving the mold is so classic cleaned manually with isopropanol, then undergoes a flame operation to activate the surface of the part to allow the attachment of the protective varnish constituting the outer layer of the room.
  • the protective varnish used comprises approximately 2% in mass of mother-of-pearl glitter with a diameter advantageously between 50 and 150 ⁇ m.
  • This varnish of glitter protection is based on polyurethane.
  • the protective varnish obtained is a special varnish which allows to give to a raw part mold output, the desired color and metallic finish appearance.
  • parts can be obtained colored with a metallic finish appearance and in particular, vehicle wheel covers automobile.
  • the protective varnish incorporating the glitter of mother-of-pearl remains the same, since it is colorless and essentially contributes to the finish metallized of said parts.
