We know that double-layer glass has color, so this is related to the coloring of the product. Here you will follow Jinhua glass gift manufacturers, Jinhua lid manufacturers, and glass custom manufacturers to understand the knowledge of product coloring methods.

1. The chemical method is to form the color of the film through chemical oxidation in a specific solution, but it must be controlled by a reference telegraph to keep the color of the product consistent. "Yin Ke Fa" is more commonly used.

2. The high-temperature oxidation method is to keep the workpiece within the process range and then immerse it in a specific molten salt. After a chemical reaction, a thick oxide film is formed, which presents a variety of different colors.

3. Ion deposition oxide or oxide method for double glass cups. This method is more suitable for processing large quantities of products. For example, the watches we usually wear. Many watch cases and watch bands are plated with titanium, and the color appears generally It is golden yellow. The principle of this method is to make stainless steel workpieces undergo vacuum evaporation in a vacuum coating machine. Because of its high cost and large investment, it is not suitable for small batch product processing.

In addition, there is the electrochemical method of coloring double-layer glass cups. This method is more popular in commerce. It is similar to the chemical method, except that the color of the film is formed by electrochemical oxidation, because of its high complexity. So it is less in industrial applications.
