The material and process principle of the metal trophy are described below.

Metal trophy material:

Generally, the metal trophy is made of copper, zinc-aluminum alloy, die-casting or forging, and the surface is electroplated and polished. Copper is resistant to oxidation and corrosion in the metal ranks, and more importantly, its color vision is more beautiful; the same zinc-aluminum alloy is also resistant to oxidation and corrosion, but zinc-aluminum alloy can be divided into two colors, one is Gold, the other is silver.

The mold is classified according to the processing technology of the processed metal. Commonly used are: stamping die, including punching die, bending die, drawing die, flipping die, shrinking die, undulating die, bulging die, shaping die, etc.; forging die, Including die forging die, upsetting die, etc.; and extrusion die and die casting die.

In the metal trophy making process, photo etching technology. A layered photosensitive optically resistant chemical film is uniformly formed on the surface of the metal trophy, and is exposed to ultraviolet rays or the like through the original film, and then subjected to development processing to form a coating layer of the chemical resistant film having a desired shape. Further, the acid or alkali solution of the etching bath is used to chemically or electrochemically attack the exposed portion to dissolve the processing technique of the metal trophy.
Metal trophies are also one of the commonly used alloy trophy processes, the principle of which is the etching process. The etching technique is a treatment technique for removing metal from a metal surface by utilizing an erosion effect on a metal surface.

Production process and principle:

The mold is classified according to the processing technology of the processed metal. Commonly used are: stamping die, including punching die, bending die, drawing die, flipping die, shrinking die, undulating die, bulging die, shaping die, etc.; forging die, Including die forging die, upsetting die, etc.; and extrusion die and die casting die.

Generally speaking, there are two kinds of electrolytic etching and chemical etching. Electrolytic etching. The mother mold is used as a conductive cathode, and the etching portion of the processed portion is concentrated by etching using an electrolyte as a medium. Chemical etching. A method in which a chemical resistant film is used to remove etching erosion and concentrate on a desired portion.
