Purpose and application scope of silver plating
Maybe you have heard the expression “electroplating” but don’t know what it is. Actually, we benefit from electroplating every day and our life is closely related to it, from a tiny screw to a big car and even a ship or plane. Boldly speaking, without electroplating, most metal products on the earth would quickly rot into a butch of scraps, and the world would be much less wonderful. Electroplating can be called a beautician for metal surfaces that can produce metal coatings with good functionality, decoration and protection on various base materials. Electroplated products are everywhere in every field and every walk of people’s daily life, even on you, so it is fair to say that electroplating plays an important role in national economic construction. As a significant constituent part of production in most industries, electroplating cannot be replaced by any other technology.
Application Fields of the Electroplating Process in Life
Protection and decoration: A lot of metal parts that we use in daily life have beautiful appearances because of one or several metal or alloy coatings. For example, most of the bathroom faucets and door knobs that we bought are copper/nickel/chrome electroplated, and most of the man-made jewelries that we wear are aluminum anodized or imitation gold, gold, or silver electroplated. These coatings are both protective and decorative.
Corrosion prevention: These products are mainly used in poor environments for industrial and outdoor purposes, so the corrosion resistance is emphasized. For example, the galvanized plate is an iron plate which is zinc electroplated to improve its corrosion resistance. Chrome electroplating can also produce a corrosion resistance coating with very wide application, which was used for wheel rims of old style bicycles. Chemical nickel-plating and anodizing are also quite common.
Property improvement: Electroplating allows some materials without special properties to acquire them by forming a coating with such special properties. For example, we know that plastics are not electrically conductive, but some special requirements need them to have electric conduction. Therefore, special technologies are used to produce an electrically conductive metal coating on their surfaces to make them electrically conductive.
Special property requirements: For example, modern technologies have high requirements for material surfaces, such as abrasion resistance, so an abrasion proof material is electroplated on these surfaces. A nano-composite graphite coating can be produced by electroplating for some metals requiring self-lubrication.
Now you have found out that electroplating is really everywhere around us. There are so many things that require electroplating that we can not live without it.
Actually, how far a custom CNC machining parts manufacturer can go usually depends on its comprehensive capabilities. Take Yijin Hardware as an example. With advanced technologies and equipment as well as experienced operating engineers, Yijin Hardware has manufactured a series of perfect precision custom CNC machining parts which make it well known both in China and abroad.
