Metal products (plated metal) General metal products include necklaces, brooches, circles, buttons, etc. The most common metal materials used in clothing are copper, iron, and alloys. Metals have their original colors, but because they are used on clothes, customers may ask for their own colors. This involves knowledge of electroplating. Generally refers to the plating of a film on an object by electrolytic reduction. The current types of use are: general electroplating, composite plating, alloy plating, partial plating, pen plating, and the like. Because the plating surface has a protective and decorative effect; it is widely used. There are also a small number of electroplatings that provide other properties such as high electrical conductivity, high light reflectivity, or reduced toxicity. The most commonly used electroplating metals are nickel, chromium, tin, copper, silver, and gold. Electroplating technology currently electroplating about 70 kinds of metals, alloy plating about 15 kinds. 1 basic process (Grinding → Polishing) → Hanging → Degreasing and Degreasing → Washing → (Electropolishing or Chemical Polishing) → Pickling Activation → (Preplating) → Plating → Washing → (Post Processing) → Washing → Drying → Hanging → Inspection package 2. Testing items of electroplating layer The electroplated product testing items mainly include appearance, adhesion, thickness, hardness, weather resistance (erosion), durability, shape, and uniformity. The reason why the discoloration of easily discolored silver plated parts after being plated in sunlight is usually caused by the etching of sulfides in the atmosphere. A small amount of sulfur and sulfide in the atmosphere can cause discoloration of the silver layer. There is another reason why silver plating of an electroplating factory is drying in the sun, that is, discoloration. The reason why the coating is discolored due to drying in the sun is that the surface of the silver layer has not been fully rinsed and left with trace amounts of silver ions, which are oxidized and discolored after photosynthesis. 3. Plating of electroplated parts The packaging of electroplated parts is very important, and the packaging of conductive oxides is particularly important because the conductive oxide film is thin and soft and can easily wear out when in contact with each other. The organic protective film is allowed to be coated on its surface, and the contact between the conductive oxide film and the bare hand is likely to generate fingerprints and contaminate the surface, so the packaging process of the conductive oxide member cannot be omitted. Generally white paper packaging. 3: Plating color: The color of our company's electroplating is generally called the guests to pick from the logo color card, but because the colors of electroplating from different manufacturers are different, we take the color of the factory to confirm to the guests, because the same is called ancient silver, but different manufacturers may make Several ancient silver. There is also the risk of blackness when electroplated colors are re-plated. Therefore, the factory must ensure that the electroplating is good and the surface should be smooth without spots. So if the guests change the plating color to ask the factory the consequences and tell the truth to the guests, if the customer bears the risk of these repeated plating and in the e-mail formal confirmation and then help him electroplating. 4: The electroplating of iron should know that iron will rust even if it is electroplated. Only poor electroplating is faster because the motor rust is rusted, and the electroplating is slower.
