According to the ranking of the faucet production areas in China, according to the quality ranking, the two towns of Heshan Jishan Town, Shuikou Town, Kaiping, Guangdong are connected, and the four major faucet brands in Fujian are Nanan, Fujian, and Jiumu, Zhongyu, Brilliant and Shenluda. The rest is Wenzhou, Zhejiang. Kaiping also has more famous brands. But why are the four leading brands in Fujian? For example, the content of copper is higher in Kaiping than in Fujian and Zhejiang.
The brand market is that before 95% of Kaiping's products were placed in foreign orders, unlike the domestic market, because domestic orders are small, making it troublesome. Therefore, the manufacturers in Kaiping have almost no big brands in China. And why is there a big brand in Foshan in China?
Because Foshan's big brand is a market opened by mature sales channels opened by the sales of ceramic tiles. So many big companies are not very famous in China. It is said that the Kaiping faucet in Guangdong is good. In fact, the key point is that Kaiping's faucet plating process is good. The design concept is in line with the European market, and all production processes are also done in accordance with European standards. All costs and quality are high.
Faucet manufacturing process
It is divided into gravity casting, low pressure casting, mechanical processing welding faucet, sand casting (not gravity casting), whether it is casting or welding, it just belongs to different manufacturing processes, regardless of good or bad. There is still a new copper alloy die-casting process, but the technology is high. Not yet universal. It is said that the cost is low and the quality is very good.
Material classification of faucet
① Brass: Brass is the most common material made by faucet. The international standard H59 / H62 copper is processed. The casting uses steel mold for gravity casting. Its wall thickness is uniform, generally 2.5-3.0 mm. Brass The faucet is characterized by: non-rust, durable, anti-oxidation, and sterilizing effect on water (the disadvantage is; lead, lead is a metal that is harmful to health, international standards require that the copper content of lead should not exceed 2.5%.
② Zinc alloy: Low-grade materials. The density of zinc alloy is lower than that of copper. The faucet is less heavy than copper. The surface of zinc alloy is easily oxidized from the inner wall. White oxide powder appears on the surface. The strength is much worse than copper. , The service life is not long, the lead content is high, if the faucet made of zinc alloy will oxidize and rot only 1 to 2 years. Now zinc alloy is mainly used to manufacture the handle of the faucet. It is made of zinc alloy die-casting, and then Chrome. Most faucets on the market are made of zinc alloy.
③Engineering plastic: ABS plastic faucet has the characteristics of corrosion resistance, aging resistance, no rust, lead-free, non-toxic, tasteless, high pressure resistance, light weight, easy construction, and low price. It is a new type of green environmental protection product. The water quality is free from the risk of rust and pollution; the plastic-made faucet is environmentally friendly, non-toxic, non-polluting, exquisite in shape, simple and convenient to install, and meets the national drinking and civil drinking water standards. This green and environmentally friendly product will be used in the faucet industry It is a urge to promote it.
④ Stainless steel: In the 21st century, health and environmental protection have gradually become the new theme of modern life. Stainless steel is an internationally recognized healthy material that can be implanted into the human body, so kitchen and bathroom supplies with stainless steel as the main material have begun to be popular in European and American countries. However, due to the high hardness and toughness of stainless steel, it is difficult to manufacture and process, which seriously affects the mass production of stainless steel faucets. Therefore, the price of real 304 stainless steel faucets is higher than that of copper. Its characteristics are: Healthy and environmentally friendly; all products are made of high-quality 304 stainless steel, which is not rusty and does not contain lead. The faucet itself will not cause secondary lead pollution to the water source, which will harm people's health and can create a healthy kitchen and living water environment for us. .
Surface treatment of faucet
1. Chrome plating: The chrome plating of faucets is the most common treatment method. The three-layer plating process uses the first layer of acid copper plating, the second layer of nickel plating, and the third layer of chrome plating. The international standard is 8 microns, and the maximum thickness of chrome plating for faucets can reach 0.12. -0.15 mm.
The electroplated layer has good bonding, fine adhesion, uniform color, and excellent corrosion resistance, which ensures that the surface of the product is bright and shiny for a long time. The electroplating detection method: After acidic 24H and 200H neutral salt spray test, it does not foam and has no oxidation. Peeling, cracking (qualified)
2. Wire drawing: wire drawing after electroplating nickel, irregular lines on the product surface
3. Bronze plating: drawing after bronze plating
4. Painting, baking, porcelain
5. Titanium plating: the surface is as bright as gold
Spool of faucet
Faucet spools range from 2 yuan for 3 yuan to more than 10 yuan. Of course we can't see it in the faucet. Cheap spools, let alone half a million switches, may leak for 1-2 years. At present, the valve core of the faucet is a ceramic valve core, which is characterized by a ceramic chip valve core with diamond hardness, which can withstand the long-term test of high temperature of 90 degrees, and the valve body with a pressure resistance of 2.5MPA. It can be used in areas with an actual service life of more than 500,000 times.
Water pressure requirements for faucets
The general household water pressure requirement is not less than 0.05Mpa (that is, 0.5kpf / cm). After using for a period of time under the water pressure condition, if the water output is found to be reduced and the water nozzle is not foamed, it can be located at the water outlet of the faucet Use a wrench tool to unscrew the mesh nozzle gently to remove impurities, and generally recover as new.
Water saving of faucet
The water output of a typical faucet is 16kg per minute. Now the faucet bubbler has been widely concerned in the market. Its advantage is that it can slow down the flow rate and keep the effluent flow below 8.3 liters / minute to achieve the purpose of saving water.
to sum up
After reading the introduction of the faucet above, everyone should also understand why the prices are different in different production areas. Domestic first-line brand faucets are branded in Kaiping Shuikou. There is a reason they don't go elsewhere to label. From copper to electroplating to accessories, the price of products is almost different. Especially after several years of use, you can feel the difference between good and bad faucets.
Poor faucet, it looks very beautiful when you take it home. However, after one year of use, there will be oxidation on the electroplated surface, and the faucet valve core is not tightly closed, dripping, etc.
The following are real cases:
Speaking of small details, a customer came to the factory once, took two leading adapters, and came to the factory to request processing.
At a glance, our factory manager saw which one was Kaiping and which was from another unknown small factory. The customer was surprised why the factory manager could see it. That's the point. Things look the same from the outside. I couldn't figure it out. Later, when the factory director explained it, we realized that he understood why he could guess accurately, and why many products with the same appearance looked cheap.
The director of the factory saw it from the processing technology. It is not that the processing technology of some small factories is not good, but that when these factories are processing joints, they are called stealing materials in jargon. Friends who learn mechanical processing will understand. The processing of the non-brand enterprises, the L hole inside the interface hole is attacked, that is, the right angle. The Kaiping enterprise is attacking small rounded corners. From a mechanical point of view, the opening of the L-bend is easier to crack. Although the small round corners cost copper, the quality is more guaranteed. Of course, if you buy it back, it may be as easy to use, and maybe you won't notice this small detail.
This is not to vilify the goods of some manufacturers. It's just that different manufacturers choose different paths. Some manufacturers make cheap products and also meet the needs of low- and middle-income people. Existence is reasonable. Hope you buy your own bathroom products!
