How to make "metal" buttons
The process of garment accessories is more and more advanced. In many cases, the true and false of a garment can be distinguished by the alloy buttons on it, because the real alloy buttons are mostly exquisite workmanship, with the characteristics of their own brand LOGO, or are all carved Or printing a brand logo, and if the button work is rough, or a large number of clothes using the same kinds of buttons and other accessories, then this dress is probably not high-end clothing. But now is a time of high-tech development. Metals can be electroplated, but have you seen that plastic can also be electroplated? The answer is yes. Through many experiments, people finally invented a new type of plastic called "ABS." Gold and silver luxury coats on their surface are chemically plated. This can sometimes be overlooked. For example, some manufacturers will use plastic buttons as the appearance of alloy buttons. Because of the conductive layer “ABSâ€, it is possible to use electroplating to “pip†metal covers such as nickel and chromium on the buttons. Now. After the roughening, chemical methods such as depositing stannous chloride, silver nitrate, and copper sulfate into the micropores on the surface of the eroded plastic product can be used to make the surface of the plastic adhere to a conductive metal film. However, when you hold them by hand, there is no impression of the texture: how is it so light? In fact, this beautiful "metal" button is not metal but plastic. In fact, plating metal coats on plastics is not an easy task. Of course, in the future development, there are new types of substitute materials that are not impossible. And the plastic is afraid of heat, and the temperature is high and it is easy to melt. Therefore, it is not possible to directly plate the metal on the surface of the plastic product. We usually visit the store will always see the small department store booth a box of beautiful buttons, some gold glittering, some silver brilliant, very beautiful and luxurious. Once this plastic hits chromic acid, the surface will be eroded, resulting in many micropores (coarsening in the electroplating industry). According to the current statistics, the plastic used for electroplating is still limited to "ABS". Because the coefficient of expansion of plastics and metals is not the same; plastic is also an insulator, and it is difficult for ions to enter.
