  1. jewelry order wholesale package ideas Gold medals are generally silver -plated. The gold medals of each Olympic Games are different, and they are owned by the championship and can be traded.
    1, before the production of the Olympic gold medal, the mold must perform a compressed process, because during the production process, the mold needs to be stamped multiple times to make the pattern on the front and back of the medal. The silver and bronze medals are made of sterling silver and pure copper, and the gold medals are special. They need to be plated on the basis of the "silver medal" in accordance with the standards of the International Olympic Committee. After stamping, part of the semi -finished products will be sent to the craftsmanship until the handicraft is made until the silver and bronze medals are completed. There are some exceptions to the production of gold medals, and semi -finished products will be sent to the Swiss laboratory with certified qualifications. Through the electrolytic process, each gold medal must be plated with 6 grams of gold, with a thickness of 75 microns, and then a special enamel must be used. Then, the gold medal returned to the Olympic Committee and engraved the name of the sports.
    2, according to the requirements of the International Olympic Committee, the host can determine the design plan and ingredients of the medal, but the proportion of the medal material must be fixed. The gold medal should contain 92 · 5%sterling silver and plated pure gold. The weight of gold should not be less than 6 grams.
    3, what is gold -plated
    "gold -plated" originally refers to a thin layer of gold plating on the surface of the utensil. Gold plating is divided into two categories, one is plated at homogeneous materials, and the other is heterogeneous material gold plating. Homogeneous material gold plating refers to gold plating on the surface of gold jewelry. Its significance is to improve the brightness and color of jewelry. Heterogeneous material gold plating refers to the surface of non -golden materials for gold plating, such as silver -plated and copper gold plating. Its meaning is to replace the color of the plated material with the gloss of gold, thereby improving the ornamental effect of jewelry, and the Olympic gold medal is obviously one of the latter.
    4, the production process is not simple
    . Due to the high requirements of the medal production process, the relevant personnel and designers must strictly check the entire production process. Gold medals need to be plated on the basis of the "Silver Medal" in accordance with the standards of the International Olympic Committee. After stamping, part of the semi -finished products will be sent to the craftsmanship to make silver and bronze medals by hand. The semi -finished product of the gold medal will be sent to the laboratory with certified qualifications. Through the electrolytic process, each gold medal must be plated with 6 grams of gold, with a thickness of 75 microns, and then a special enamel must be used.
    5, how to control gold content
    During the production process, if the gold content of the gold medal is less than 6 grams, it will not be qualified. "To control the weight of this gold plating, the focus is on controlling the electroplating time and current size. At the same time, the metal surface color must be uniform, the grains are dense, and the phenomenon of local shiny or gold -plated layer is not allowed. R n 6, for this reason, each medal will be weighted with electronic balance before plating, and then plated in the electroplating groove. At the same time, because the current of each position during electroplating is different, the staff will use the medal number, electroplating, and plating. Exchange positions after a period of time, and repeatedly weigh it to ensure that the weight of the same batch of medals is the same. In order to control the time and effect, several medals with similar weights are often placed together. The gold medal gold -plated weight is well controlled at 6 ~ 6.1 grams.

    The prescribed

    before formal formulation of the 1978 Olympic charter, the production of medals did not make specific regulations. According to the Olympic charter formulated in 1978, the diameter of the Olympic medal medal must not be less than 60 mm, and the thickness must not be less than 3 mm. Gold and silver medals must be made with silver with a purity of 92.5%. The gold medal must be placed at least 6 grams.

    The design and production of the Olympic medals has always been responsible for the organizing committee of the host city. The International Olympic Committee and the National Olympic Committee have not participated.

    The previous Olympic Games seems to have made a gold medal with pure gold once, and which session can't be remembered.

  3. wholesale jewelry showcase display Anyone who has learned chemistry knows that metals like pure iron are very soft. Only raw iron is hard, (raw iron, that is, a mixture of multiple metals). Then mixed with other metals and smelted high -hardness, steel.
    . In order to extend the collection time of the gold medal, the collection significance must be improved. Each athlete does not want to make a mistake because of a certain mistake. Falling the gold medal to the ground and turning it into an ellipse cake. Because pure gold is easier to deform than iron. People who have played gold know it.
    It is not our country's stingy ^^! It is the Olympic Games.
