  • Cloisonne craft is one of the metal craft techniques to apply a glaze glaze on the base metal, such as gold, silver, copper, and to adhere the glaze to the base metal by high temperature heat treatment under a temperature condition of 700 ⁇ 900 °C.
  • Glazes contain organometallic oxides and are produced through heat treatment. These glazes develop in beautiful colors and, when heated to high temperatures, they are melted on the base metal as glossy glass.
  • Cloisonne crafts should be lacquered on both the front and back to prevent deformation due to the coefficient of thermal expansion.
  • the glaze-fixed cloisonne crafts have excellent luster, refractive index, reflectance, etc., and various colors are beautiful, so design and color expression are free.
  • the expansion coefficient is similar to the base metal, it adheres well to the metal without cracking, and does not corrode well due to acid, alkali, gas, etc., and does not absorb water, and thus has excellent cold resistance and fire resistance. Therefore, it is also possible to protect the base material, there is no discoloration as long as there is no damage by external force, it can exhibit the beauty of semi-permanent color.
  • Cloisonne crafts were used not only as traditional ornaments, but also as decorations for various household items.
  • the thickness of a general watch dial to be used as a watch component should be about 0.4 to 1.0 mm, but if the dial is made with a cloisonne craft, the thickness of the cloisonne (0.6 to 2.0 mm) is added to the base metal (0.8 to 2.0 mm). There is a limit that can not be manufactured with the watch dial because it adds up to at least 1.4mm.
  • the flatness of the watch dial is a very important factor because it must be tightly coupled between the movement of the watch and the case.
  • the glaze is applied to the base metal before and after, and the glaze is melted and fixed through high temperature heat treatment of about 700 to 900 ° C.
  • the glaze is cooled to room temperature, deformation occurs due to the difference in thermal expansion between the cloisonne and the base metal, and the flat base metal is warped in a dome shape because the heat shrinkage of the base metal is larger than that of the cloisonne.
  • cloisonne is very weak against external shock because of its glassy material.
  • the dial is a part that is assembled between the case and the movement. If the external shock applied to the case is transmitted directly to the Cloisonne watch dial, there is a possibility that the small impact will easily crack.
  • the index of the general clock dial shows the exact position by printing or by attaching a part through a hole.However, if the index is expressed by using the existing cloisonne crafting technique, the cloisonne powder will be displayed at high temperature even if the position is accurately indicated by hand. Since some slip occurred at the time of melting, it was difficult to accurately position the index.
  • the present invention has been made to solve the above-mentioned problems, and has a flatness while minimizing the thickness of the watch dial, has no contact surface crack between the case and the dial, and uses the lacquer work of the lacquer work of accurate index position. Its purpose is to provide a manufacturing method and a clock dial and a clock produced by such a manufacturing method.

  • the watch dial By manufacturing the watch dial through the manufacturing method of the present invention, it is possible to minimize the thickness of the watch dial, obtain desired flatness, prevent cracking of the watch metal case and the dial contact surface, and precisely position the index. I can catch you.

Metal selected from the group consisting of may be used, but is not limited thereto.
  • Cloisonne is an artificial gemstone that has beautiful luster with gloss and excellent reflectance and refractive index. It is applied when glaze mainly containing silica, soda ash, borax, and dispersion is applied to the base metal and heat treated at 600 to 1000 °C. It is solidified in the process of melting and cooling and is formed by being fixed to the base metal.
  • Such lacquer has the advantage that the color can be produced in various colors because the heat treatment temperature is different depending on the glaze composition and thickness or the color of the base metal.
  • the base metal is first prepared, and then the dial design is designed in consideration of the shock absorbing surface. The engraved shape is then engraved using the corrosion or press method.
  • Corrosion is a surface treatment technique in which acid is brought into contact with a metal surface to dig a metal surface to a certain depth, usually by immersing the metal in an acid solution.
  • the parts that do not want to be corroded are kept by the anticorrosive to prevent the acid solution from coming into contact with the metal to maintain the original surface.
  • the press method is a method of pressing or pressing a metal plate with a mechanical force through a metal mold, or engraving a surface or processing it into an uneven shape.
  • the use of the template is widely used in the industry because of the advantage of being able to duplicate several copies of the same form in a short time.
