Definitions

  • the present invention relates to a method of marking a part hot metal, in particular a mechanical part made in a foundry, in order to identify said part during the various stages of its manufacturing.
  • the Applicant has posed the problem of marking alphanumeric characters on a hot aluminum part and more specially a hot aluminum casting having a temperature higher than 150 ° C.
  • poteyage products for a completely different application most often to protect against corrosion by cast aluminum from metal steel elements of the mold or to help with demolding.
  • the process according to the present invention has the advantage, inter alia, allow the marking of hot aluminum cast parts at most near the molds, that is to say the place of actual manufacture of said parts, which avoids any risk of manual intervention by operators. In this way, it is now possible to control the tolerances on the said parts and to determine the influence of the most important to some extremely delicate manufacturing processes such as that of a cylinder head, for example.
  • 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 dimensions of the part are: 150 x 100 x 10 mm.
  • 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.
  • fatty soup known under the trade name Antietam PW, sold by AMPERE INDUSTRIE.
  • the hot part is held vertically during the removal of the so as to create a flow curtain on the room.
  • the cleaning product melts and spreads over the surface to be marked.
  • the marking is carried out after melting the oils and waxes.
  • the marking time for 11 characters 6 mm high is about 12 seconds.
