When it comes to enamel medals, everyone in the medal making industry knows that this is the highest grade medal in the medal! Which enamel craft is it? Simply put, a craft made by attaching a glassy enamel glaze to a metal surface and baking it at high temperature is called enamel. Let’s take a closer look at the history, craftsmanship and production process of enamel medals and enamel crafts.
Enamel is a transliterated word from a foreign language, also known as “Flang”, “Falan”, etc. It originated from the ancient western region name Fulin in the Sui and Tang Dynasties of China. Formally set as a synonym for artistic enamel. The enamel technique began to prevail in the Ming and Qing Dynasties. There were official kilns for professional production in the Ming and Qing Dynasties. However, due to the many limitations of the production technology and craftsmanship in the Ming Dynasty, both in terms of color and product, were relatively single. The volume and shape of the enamelware also ranged from small to large, from concise to complex, from pure viewing to both practical and practical, and to the middle and late Qing Dynasty, as the production technology gradually matured, the patterns became more and more complex, and the inspection tools Craftsmanship, artistry and ornamentality.
Traditional enamel crafts are generally produced in the following ways. The first is reeling enamel. The copper wire is patterned, adhered to the tire, and then filled with various enamel glazes inside and outside the pattern frame, baked in a kiln, and repeated several times. , And then through grinding and gold plating procedures. The second is filled with enamel. Its process is generally similar to that of filigree enamel, except that the decoration on the surface of the enamelware is formed by engraving, etching or stamping, and then baked at high temperature. The third is to paint enamel. First, burn a layer of opaque glaze on the inside and outside of the metal tire as a base, then apply the top glaze and painting patterns on the base glaze according to the design pattern, and then enter the kiln and bake it at 800 degrees. But now the enamel medal is very different from the traditional enamel technology. In today’s high-tech developed society, colorful paints and pigments, modern color modulation technology, etc., provide people with different visual senses. Enamel medals are easy to make and more colorful. The main process flow is as follows.
The first step is molding. According to the drawings, make molds, and use computer software to make files that can be used by the engraving machine. Most of the current molds are machine engraving. Because they are fully automatic machine engraving, carved birds and beasts, portraits of people, and landscapes are vivid. A lot of glory for the three-dimensional effect of the medal.
The second step is to make the embryo. Use a carved mold to press out the required copper embryo. Generally, copper is used as the blank. Sometimes, if necessary, the necessary accessories are welded with silver powder, such as safety pins or thorns. Horse needles, etc., and then pickling.
The third step is to apply enamel. According to the designed drawing, the prepared enamel material is filled in layers. Generally, it is higher than the metal wire frame, and then it is baked in a high-temperature oven to fully cure the color material to a certain degree of hardness. The next process is up.
The fourth step is smoothing. Generally, the metallographic grinding wheel is used to smooth the paint surface, so that all the metal wire frames are exposed, and the glaze surface is flat. If there is any unevenness, it needs to be recolored, baked and smoothed until inspection. After passing, it will enter the next process.
The fifth step is polishing. First rough polishing, then fine polishing, adding lubricating materials such as paraffin to make the surface usually fine, polished products, smooth surface like a mirror, highly ornamental.
The sixth step is electroplating. Electroplating can be gold-plated, nickel-plated, chrome-plated, copper-plated, etc. according to customer requirements. The polished product can be electroplated after pickling. After plating, the enamel medal will be washed with water and dried. A meticulously made enamel medal with American beauty will be completed.
Enamel medals are the highest-grade medals in the making of medals. Sometimes they are also called hard enamel or true enamel medals. They are made of copper (usually copper or copper, etc.) and are baked at high temperature (usually 800 degrees). Not only is the workmanship fine, but also the patience, it can be stored for a long time without discoloration and oxidation, it is the first choice for medal collectors. However, with the continuous improvement of the medal technology, the imitation enamel medal is similar to the true enamel and its craftsmanship. The most important thing is that its price is much cheaper and is being loved by more and more people. Therefore, in the current market, many people refer to enamel, often referring to imitation enamel medals.
