At present, most of the award ceremonies of major film festivals, and the annual meetings of companies and schools use metal trophy as prize. Today's metal trophy is mostly new and fashionable, with bright colors, noble and elegant, and can often greatly reflect the vivid beauty of metal trophy. Below, Pinstar will briefly introduce the material and process principle of the metal trophy.

1. The material of the metal trophy
Common metal trophies are usually made of copper, zinc-aluminum alloy by die casting or forging. The surface is electroplated and polished, and the overall is stable and generous. Copper is resistant to oxidation and corrosion in the ranks of metals, and more importantly, its color vision is more beautiful; the same zinc aluminum alloy is also a metal resistant to oxidation and corrosion, but zinc aluminum alloy can be divided into two colors, one is gold, the other is silver.

2. The production process of metal trophy
The molds are classified according to the processing technology of processing metals. Commonly used are: stamping dies, including punching dies, bending dies, drawing dies, turning dies, shrinking dies, undulating dies, bulging dies, shaping dies; forging dies, including forging dies for die forging, upsetting dies; as well as extrusion dies and die-casting dies.

In the process of making personalized medals trophies, photo-etching technology often plays a key role. The etching technology can form a layered optically active film uniformly on the surface of the trophy metal. Etching technology can use the original image film to use ultraviolet light and other exposure methods to develop the metal trophy to form a chemical resistant film of the desired shape. The acid or lye of the etching bath is then used to form chemical or electrochemical erosion on the specific exposed part of the trophy to dissolve the metal trophy.

All in all, the so-called etching technology is a processing technology that uses the corrosive effect on the metal surface to remove excess metal from the metal surface. Generally speaking, there are two types of electrolytic etching and chemical etching. Electrolytic etching. Use the master mold as a conductive cathode, and use the electrolyte as a medium to intensively implement the etching and removal method for the processed parts. Chemical etching is a method that uses a chemical-resistant coating to remove the etching and erosion and concentrate the effect on the desired part.
