The main production materials are red copper and zinc alloy, which are stamped or die-casted with three-dimensional molds, and then equipped with baking enamel and imitation enamel. Compared with other types of badges, three-dimensional badges have a stronger three-dimensional sense and stronger expressiveness. Embossed medallions, 3D badges, 3D medals, etc. are three-dimensional badges with a relief effect.
The three-dimensional badges made of copper are generally stamped. Stamping is the use of presses and molds to apply external forces to plates, strips, pipes and profiles to cause plastic deformation or separation. Thereby, a method for forming a stamped part having a desired shape and size is obtained. Stereoscopic badges made of zinc alloy are generally made by die-casting. Die casting process is short for pressure casting. It is a casting method in which a molten alloy liquid is poured into a pressure chamber, a steel mold cavity is filled at a high speed, and the alloy liquid is solidified under pressure to form a casting. Die casting is distinguished from other casting methods by high pressure and high speed.
The enamel badge (also called cloisonne badge) is a high-end badge in the badge process. It is mainly made of red copper and is made of enamel powder at high temperature above 850 degrees. It is commonly used in the production of military, state agency badges, and special memorable badges, commemorative coins, medals, etc.
1. The color place is almost flush with the metal lines.
2. It has enamel powder, and the color is dull and does not fade.
3. It is hard and brittle, and the sharp object cannot puncture.
4. It is high temperature resistant, and it needs to be grilled in high temperature above 850 degrees to dissolve into the color.
5. If the raw materials are relatively thin, high temperature will make the product have radian / curvature (not bending effect).
6. The back surface is not a bright flat surface, and there will be irregular small pits. This is due to the high temperature ablation of impurities in the red copper.

Imitation enamel badge
It is mainly made of zinc alloy, the surface is imitation enamel pigment, and it is fired at high temperature. The craft is similar to enamel badges. Due to its limited color, enamel badges have a variety of colors. Because the imitation enamel badge uses color paste instead of enamel, the color paste has more colors to choose from, and it looks a bit grainy compared to the surface of the enamel badge. The surface of the imitation enamel badge can also be screen printed to apply various colors. It has met the requirements of customers and does not change important design elements in the design, such as various logos, names, etc. Moreover, since imitation enamel badges are cheaper than real enamel badges and the effect is quite good, they have gradually replaced true enamel badges.
Difference between imitation enamel badges and lacquered badges
The surface pattern of the imitation enamel badge is on the same plane as the text. It feels slightly raised when you touch it, but the paint badge has a bumpy feeling.
