Plating process for cases requiring luster and aesthetic appeal, as well as high corrosion resistance.
Chrome plating refers to the process of depositing chromium metal onto an object. Chromium metal combines with oxygen in the atmosphere to form a transparent and extremely thin passive film on the surface, which provides corrosion resistance, luster, and hardness. Chrome plating can be broadly categorized into two types: "decorative chrome plating (nickel chrome plating)" and "hard chrome plating" (also known as hard chrome plating). Although both are referred to as chrome plating, they are distinguished by the thickness of the film. However, when people generally refer to chrome plating, they often mean "decorative chrome plating."

basic information
- High light reflectivity Decorative chrome plating has the property of efficiently reflecting light. The shiny silver-colored items commonly seen in urban areas are chrome-plated and emit a beautiful luster that is even used in accessories. Due to its luxurious and clean appearance, it is often adopted for equipment used in museums, car emblems, and in medical settings. - High heat reflectivity Plated products can oxidize and discolor if left at high temperatures for extended periods. However, decorative chrome plating has high heat reflectivity and a slow oxidation reaction, so under certain conditions, it does not oxidize or discolor even when left at high temperatures. - High corrosion resistance Decorative chrome plating also has the characteristic of high corrosion resistance. This is because nickel plating is used as a base layer for decorative chrome plating, which enhances its corrosion resistance. With properties that make it resistant to discoloration and corrosion, decorative chrome plating is used in a wide range of applications, including residential equipment, automotive parts, and industrial products.
