There are various medal making techniques, and common ones include:

Stamping: Using molds and stamping equipment to apply pressure to metal materials to form the desired shape and pattern.

Die casting: Injecting molten metal material into a mold and solidifying it into shape through pressure.

Bite plate: Corrupt raw materials with chemical solutions to form concave patterns.

Enamel: A traditional craft in which enamel powder is applied to a metal surface and fired at high temperatures to form a smooth, hard, and brightly colored enamel layer.

Imitation enamel: The texture and color are similar to real enamel, using resin materials, with relatively low prices, suitable for making high-end badges, commemorative medals, etc.

Baking paint: A layer of baking paint is applied to a metal surface, which is then baked at high temperatures to form a hard, smooth, and brightly colored coating.

Printing: Printing patterns and text onto metal surfaces using printing techniques.

Electroplating: By electrolytic action, a layer of metal such as gold, silver, copper, etc. is plated on the surface of the metal to increase the luster and texture of the medal.

Coloring: Using baking paint, enamel, printing and other processes to add different colors and patterns to the medal.

Polishing: Use a polishing machine to polish the surface of the medal, making it smooth and shiny.

Welding: Weld and fix the accessories of the medal, such as pins, ropes, etc., to the main body of the medal.
