A medal is a certificate issued to the winner of a variety of competitions. It is usually made of metal. According to the shape, it can be divided into: medal, medal and medal plate. According to different uses, it can be divided into: advanced individual medal, advanced collective medal, authorized medal and so on.

Metal medal making materials: copper, iron, zinc alloy or gold, silver and other metal materials.

Copper is one of the earliest ancient metals discovered by human beings. As early as 3000 years ago, human beings began to use copper as an element symbol, with atomic weight of 63.54, specific gravity of 8.92 and melting point of 1083oc. Pure copper is light rose or light red. Oxygen is formed on the surface and copper is used. The appearance of copper film is copper. Copper has many valuable physical and chemical properties, such as its high thermal conductivity and electrical conductivity. Chemical stability copper is one of the earliest ancient metals discovered by human beings. As early as 3000 years ago, human beings began to use copper.

Metal copper, element symbol Cu, atomic weight 63.54, specific gravity 8.92, melting point 1083oc. Pure copper is light rose or light red. After the formation of copper oxide film on the surface, the appearance is copper. Copper has many valuable physical and chemical properties, such as high thermal conductivity and conductivity, strong chemical stability, high tensile strength, easy fusion, corrosion resistance, plasticity and ductility. Pure copper can be drawn into very thin copper wire and made into very thin copper foil. It can form alloy with zinc, tin, lead, manganese, cobalt, nickel, aluminum, iron and other metals.

Zinc, tin, lead, manganese, cobalt, nickel and aluminum are light metals. Their compounds are widely distributed in nature. The content of aluminum in the earth's crust is about 8% (by weight), second only to oxygen and silicon, and the third is aluminum, iron and other metals to form alloys. A bit. As one of the metals, it not only has light weight and strong texture, but also has good ductility, conductivity, thermal conductivity, heat resistance and nuclear radiation resistance. It is second only to iron and steel, and is the second major basic raw material for the economic development of Jinmin. Genus. Aluminum has special chemical and physical properties, which is the most commonly used industry nowadays.

Design, production and processing technology of Metal Medals

Medal making process:

Process 1: Design medal draft. With the popularization of computer technology, computer drawings replace the previous manual drawings. Adobe Photoshop, Adobe Illustrator and Corel Draw are commonly used in the design of medal draft. If you want to generate 3D medal draft, you need the support of 3D Max and other software. As for color system, Pantone solid coated is usually used, because Pantone color system can better match colors and reduce the possibility of color difference.

Process 2: making medal mold. The manuscript designed by the computer is imported into the program of the precision engraving machine, and the cutter path is made to carve the mold. In the process of carving, the thickness of the knife pattern should be paid attention to. After carving, compare the mold according to the figure to see if there is any missing. Finally, the mold should be heat treated to enhance the hardness and durability of the mold.

Process 3: suppression. The frequently heat-treated mold is installed on the platen, and the pattern is transferred to different medal making materials such as copper or iron.

Process 4: blanking. Use the tool mould made in advance to punch down the product according to its shape.

Process 5: polishing. Put the products punched down by the die into the polishing machine to remove the burr and improve the finish of the products.

Process 6: Welding medal accessories. Solder the back of the product with medal standard accessories or customer required accessories.

Process 7: plating and coloring medals. According to the requirements of customers, the medals can be plated with gold, silver, nickel, red copper, etc., then the medals can be colored according to the requirements of customers, and then baked at high temperature to strengthen the color fastness. Through this step, a complete medal meeting the requirements of the guests will be produced.

Process 8: pack the medals according to customers' requirements. Packaging is generally divided into ordinary packaging and high-end packaging, such as brocade box, etc. we generally operate according to the requirements of customers.

In recent years, the value of medal collection has become more and more prominent, especially the medals and commemorative medals made of metal materials have become the mainstream of medal production, such as enamel medals and imitation enamel medals in high-grade medals, as well as paint medals, and Metal Medals made of iron with relatively low price. Metal medals can be processed into furniture by paint or soft enamel process Fumei medal with rich colors. Metal medal has strong three-dimensional sense, and various patterns are outstanding. It is a kind of medal product used by high-end users.
