Many buttons look the same to our naked eyes, but the materials are not the same. Many times we can't tell the difference. Today, China's Button Trading Network is working with you to identify which buttons are invisible to the naked eye. First, the difference between button resin and plastic 1, plastic refers to the resin as the main component, plasticizers, fillers, lubricants, colorants and other additives as ancillary components, in the process of flow molding material. 2. The resin usually has softening or melting range after being heated. When it is softened, it tends to flow under external force. At room temperature, it is a solid, semi-solid, and sometimes liquid organic polymer. Broadly speaking, any polymer that can be used as a raw material for processing plastic products is called a resin. It can be seen that resin is one of the raw materials for plastics and plastic is the finished product of resins. Unformed resin, plastic after molding. Second, the difference between resin buttons and plastic buttons 1, and plastic buttons are made of solid materials, most of which are resin pellets, injection molding through injection molding machines and molds. The difference between resin buttons and plastic buttons is the difference in processing methods. 2. The resin button is a liquid substance that is formed by heating, cooling, solidifying, cutting, and other processes in a special pipe or other cavity, or it is formed after being solidified by coating liquid resin on the roller surface, and then enters the subsequent processing. Because the processing methods of the two materials are different, the resulting finished products have different effects. The surface of the resin button is smooth and has a thick appearance, and it should also be more extensive. The plastic buttons can produce various styles of buttons according to the changing shape of the mold, and it is also easier to electroplate with respect to the resin buttons. Commonly used buttons include plastics, metals and natural products. After being molded by different processes, they are not easily identified from the appearance. The following Guangzhou Senma hardware button factory to teach you how to identify the button material. 1, metal buttons Metal buttons are divided into copper buttons, iron buttons and alloy buttons three. To distinguish between copper buttons and iron buttons is relatively simple, just use the magnet to try it. Another method is to scrape off the plating on the surface with a hard object. The brass buttons will have a brass color and the iron buttons will be black. The alloy button is formed by die-casting, and the inside is solid, so it has a mold line and is heavy. In the molding process, it is basically polished and polished. 2, plastic buttons In plastic buttons, it is divided into plastic buttons and resin buttons. Most of the resin is carved by mechanical and then polished, so the surface is without any traces, more clean and smooth. However, the resin buttons are relatively easy to break and will soften when placed in boiling water. Plastic buttons are generally made by die-casting, so there is a line at the edge of the button. This line is also referred to as a mold line. Some factories use aesthetic processing to remove the line. In comparison, its weight is slightly lower than that of the resin. Each different material needs to be processed into buttons through different processes. However, after some buttons are formed, it is difficult to judge its material appearance.
