Electroplating process is an indispensable and important part of every metal button product. (Note: while pursuing fashion and lightness, some unsaturated resin buttons and ABS plastic buttons also adopt electroplating process.)
- From the type of electroplating, it can be divided into barrel barrel plating and hanging plating.
- Barrel plating is used for products with low requirements on the appearance of metal buttons. Barrel plated metal products will not be very shiny. During the polishing process, the button surface will even leave scratches, but it will not be very clear. Although there is bright barrel plating, the overall effect is not as good as hanging plating. Of course, the cost of barrel plating is also relatively low. Products with low surface requirements or small area are suitable for barrel plating, such as small air holes, five claw buttons on the ring surface, three pieces of four button buttons, etc., which are generally used for barrel plating.
- Hanging plating is used for products with high requirements on the appearance of metal buckle products, such as alloy four-way buckle surface, alloy three-step buckle, belt buckle, hardware chain, etc. The advantage of hanging plating is that the surface is not only smooth, but also as bright as a mirror. But some bicolor colors cannot be handled.
- From the perspective of environmental protection, it can be divided into nickel plating and nickel free plating. Electroplating is the process of changing the color into a thin film and attaching it to the product surface through chemical treatment. If the “nickel” component is penetrated in the electroplating process, the product will not meet the national environmental protection standards (especially the European and American countries have higher requirements for non nickel). This is nickel plating; If there is no penetration of “nickel” in the electroplating process, it is nickel free electroplating. Of course, nickel free electroplating also has requirements for raw materials. If the raw material itself contains “nickel”, then nickel free electroplating cannot be completed. (for example, the raw material is iron, because it contains too much “nickel” component, so products made of iron cannot be plated without nickel.)
- Commonly used electroplating colors include: Black Bronze, green bronze, red bronze, gun color, two-color gun black, bright silver, silver, imitation gold, rose gold, etc.
