[0002] Buttons are the fasteners used to connect the two sides of clothes. Their original function was to connect the front of clothes. Now they have gradually developed into something more artistic and decorative in addition to maintaining their original functions. They are also a representative of personalization and multifunctionality of clothing.

[0003] Buttons can be classified into natural, chemical and other materials according to their materials. Among them, chemical buttons are further divided into organic buttons, resin buttons, combination buttons, urea buttons, spray-painted buttons, electroplated buttons, Qin buttons, etc. With the rapid development of the button industry, the requirements for buttons are also increasing. They need to have good wear resistance, high temperature resistance, corrosion resistance, various varieties, and bright colors. Sometimes, it is also necessary to deal with many buttons of different styles and shapes for clothing; therefore, various buttons made of various materials have also been put on the market, competing for excellence, such as gold-plated buttons, silver-plated buttons, threaded buttons, carved buttons, blue-burned buttons, material buttons, etc. There are also precious white jade Buddha hand buttons, gold-plated pearl buttons, three-inlaid jade buttons, gold-inlaid agate buttons, coral buttons, beeswax buttons, amber buttons, etc., and even diamond buttons; the patterns of buttons are also rich and varied, such as broken branches of flowers, fortune, longevity, etc., which can be said to be everything, meeting the different requirements of various fashion clothing.

[0004] The preparation process of metal buttons is as follows: metal button manufacturing process: opening size mold, opening button surface mold (shape) - flower mold (LOGO / pattern, etc. - trial mold - making samples - roughening - oil washing / polishing - electroplating - other process treatments (oiling / laser / silk screen) - inspection / testing - packaging and delivery, among which the surface is coated during the electroplating process. Coated buttons refer to the process of coating the button surface after effect treatment and modification, or coating treatment can be performed first and then other effect treatments or modifications are performed, so as to form a variety of patterns or font effects on the button surface.

[0005] The surface coating treatment includes preliminary treatment (oil removal and rust removal) - spray primer on the button surface → coating → effect treatment → spray topcoat. The coated buttons produced in batches are coated on the product surface, then the effect treatment is performed and then transparent paint is sprayed for protection, which makes the button surface effect single and can only achieve the basic color after coating (bright silver, bright gun or matte silver, matte gun, etc.). The button surface is a direct coating color, and the coating color is relatively single, and the market demand is not high. In addition, the split buttons also need to be coated first, then riveted, and then painted. During the production process, the coating layer on the product surface is easily scratched, which leads to many problems such as affecting the overall quality of the product and failing to meet customer needs.
