Common manufacturing technology of badges, medals and commemorative coins
Cloisonné(enamel) is the most traditional badge human color information. Its color can be preserved for 100 years without changing color.
All color ore powder is imported from Japan.
The color powder filled on the badge must be fired at 800 ℃ to melt into one, and then cooled at room temperature.
In general, we have to burn various colors of powder several times to ensure that the product color will not be mixed.
Hard enamel method, because more than other into color information in the process of more complex, so the unit price is also the most valuable.
Raw material: red copper.
Color: ore, ground into powder, imported from Japan.
Picture: die pressing (stamping method).
Production process: mold carving → heavy pressure forming → external cutting → color filling → high temperature 800 ° C firing → grinding stone → welding accessories → polishing → electroplating → packaging.
Imitation enamel.
Imitation enamel was also named soft cloisonné or composed of cloisonné, created in early 1990.
It replaces some genuine enamel products, because the surface is similar to genuine enamel, but it can reduce the cost, deliver more quickly and have more colors to choose from.
Customers always compliment imitation enamel products because their color is bright, smooth and glossy.
Because of the high texture, you will take good care of them, just as you take good care of your jewelry.
Although hard enamel and imitation enamel have a high similarity, we can still see the difference between them. Use sharp objects to poke the color block. If you can point the color to enter, it is imitation enamel. If you find it difficult, it is real enamel product. Because the color information of real enamel is ore powder, so the color surface is solid.
Raw material: red copper or bronze.
Color: colorful resin.
Picture: die pressing (stamping method).
Color chart: Pantone color ticket.
Production process: mold carving → heavy pressure molding → external shape cutting → welding accessories → color filling → baking temperature 80 °? 100 ° C → surface grinding → polishing → electroplating → packaging.
Copper baking paint.
Generally, the price is cheaper than that of real enamel and imitation enamel badges. It is also an ideal material that needs delicate details or 3D planning. All copper enamel badges will be polished on the front, so the metal part of the product will leak luster. It is optional whether it needs to be covered by epoxy or not.
Raw material: bronze or red copper.
Color: baking paint.
Picture: die pressing (stamping method).
Color chart: Pantone color ticket.
Production process: mold carving → heavy pressure forming → external shape cutting → parts welding → polishing → electroplating → color filling → baking temperature 160 ° C → epoxy cover (if necessary) → packaging
Metal is not colored
The production process of this product is the same as that of real enamel, imitation enamel and copper baking paint, but we don't fill in any color, so we give this project a special title of "metal colorless badge"“
Because this method does not fill color, so we have a variety of options, such as sandblasting, fog paint, or a variety of ancient plating function of the scenery to choose from, so as to highlight and focus on the level of detail.
Raw material: red copper or brass or iron.
Color: None.
Picture: die pressing (stamping method).
Production process: mold carving → heavy pressure molding → external shape cutting → parts welding → polishing → electroplating → packaging.
