We all know that making badges, drawing and die-casting or stamping is one of the essential processes, but there is one more important process that we should pay attention to, that is, electroplating, electroplating also plays an important role in badge making. For the purpose, let's take a look at the several functions of electroplating in the making of badges: firstly, by electrolysis, a technique of depositing a good metal coating with different properties and matrix materials on the metal badge product is first deposited. Electroplating makes the surface layer of the badge uniformer than the hot dip layer, generally thin, ranging from a few microns to tens of microns. By electroplating, it can obtain decorative protection and various functional surface layers on mechanical products, and can also be repaired. Parts that are worn and mishandled. In addition, there are different roles in plating requirements for various badges.
1. Badge copper plating: use for bottoming, improve adhesion of plating layer, and corrosion resistance
2. Badge nickel plating: use the bottom or make the appearance, improve the corrosion resistance and wear resistance, (where the chemical nickel is more resistant to chrome in modern technology).
3. Badge gold plating: Improve the conductive contact resistance and improve signal transmission.
4. Palladium-plated nickel: Improve the conductive contact resistance, improve signal transmission, and wear resistance higher than gold.
5. Tin-plated lead: Improves the welding ability and is quickly replaced by other substitutes (because lead is mostly changed to bright tin and matte tin).
