Definitions

  • the marking of hot metallic objects has so far been treated in various ways both in terms of processes and of marking compositions such as recalled in document FR-A-2 308 999.
  • the marking method of the present invention is advantageously applied to an aluminum part.
  • the coating product deposited on the hot aluminum part has preferably a determined composition chosen based on or derived from at least a natural and / or synthetic oil and / or wax and comprising possibly a solid charge.
  • mixtures of the mixture type may be mentioned saturated and unsaturated fatty acids such as, preferably, the mixture of acids saturated C8-C18 fats and unsaturated C18 fatty acids.
  • mixtures of the oil mixture type may be mentioned paraffinic and synthetic wax.
  • the poteyage product useful in the context of the present invention should advantageously comprise a mixture of the type mixture of paraffinic oils and synthetic wax, associated with preferably a solid filler.
  • a solid filler As an example of solid charge, we can cite a mixture of graphite and aluminum.
  • said solid filler is in the form of powder in suspension in mixtures of the paraffinic oil and wax type synthesis at a rate of 2% to 10% by weight, preferably 6% by weight per relative to the total weight of the composition.
  • a rate of 2% to 10% by weight, preferably 6% by weight per relative to the total weight of the composition we can cite the product sold by the company AMPERE INDUSTRY under the trade name Antietam PW.
  • the text to be marked is as follows: 11 alphanumeric characters arranged on two lines, the height of the characters being 6 mm.
  • the marking head is mounted in a double envelope with circulation of air between the two walls.
  • the coating product melts and spreads over the surface to be marked.
  • the marking is carried out after melting the oils and waxes.
