A look at the differentiated routes from the faucet process in each region
China’s faucet production, according to quality ranking, then, Guangdong Kaiping Shuikou Town Heshan Site Mountain Town two towns are linked together, down is Nan’an, Fujian, the four major domestic faucet brands is Fujian, Jiumu, Zhongyu, brilliant, Shen Lu Da. In the rest is Wenzhou, Zhejiang. Kaiping also has, more famous brand. But why the faucet four brands in Fujian. For example, the content of copper, Kaiping is higher than Fujian and Zhejiang.
The brand market is the former Kaiping’s products are 95% of foreign orders, unlike doing the domestic market, because the domestic orders are small, manufacturing trouble. So Kaiping’s manufacturers have almost no big brands in China. And why is there a big brand of Foshan in China?
Because the big brand of Foshan is a mature sales channel to open the market by the tile sales. So many big companies in the country is not very famous. All said Guangdong Kaiping faucet good, in fact, there is a very key point is Kaiping faucet plating process. The design concept is in accordance with the European market alignment, all the production process is also in accordance with the European standard. All cost, quality are high.
Faucet manufacturing process
Sub gravity casting, low-pressure casting, machining welding faucet, turn over the sand casting (no gravity casting good) casting or, welding, just belong to the manufacturing process is different, not good or bad. Now there is ** a new out of a copper alloy die-casting process, but the technical content is high. Has not been popularized. It is said that this kind of low cost, quality is very good.
The material classification of the faucet
① brass: brass is the faucet manufacturing ** universal material, international standard H59/H62 copper processing, casting using steel mold for gravity casting, its wall thickness uniform, generally in 2.5-3.0 mm. Faucet made of brass is characterized by: non-rusting, durable, with antioxidant, the water has a sterilizing effect (drawback is; lead, lead is a health hazards of metal, international standards require that the copper content of lead shall not exceed 2.5%.
② zinc alloy: low-grade materials, zinc alloy density than copper, copper faucet feel not heavy, from the inner wall of the surface of the zinc alloy is easy to oxidize, the surface will appear white oxide foam. Strength is much worse than copper, the service life is not long, lead content is high, if the faucet made of zinc alloy only 1 to 2 years will be oxidized rotten. Nowadays, zinc alloy is mainly used to make faucet handles. It is a zinc alloy that is die-cast and then chromed. Most of the faucet handles on the market are zinc alloy.
③ engineering plastic: ABS plastic faucet has corrosion resistance, anti-aging, no rust, no lead, non-toxic, tasteless, high pressure, light weight, easy construction, low price, etc., is a new type of green environmental protection products so that the water quality without the risk of rust corrosion and pollution; plastic faucet refined from environmental protection, non-toxic, pollution-free, exquisite shape, simple and convenient installation, in line with national drinking water, civilian drinking water standards. This kind of green and environment-friendly products will be a kind of trend in the faucet industry and should be promoted vigorously.
Stainless steel: In the 21st century, health and environmental protection have become the new theme of modern life. Stainless steel is an internationally recognized healthy material that can be implanted in the human body, so stainless steel kitchenware has become popular in Europe and America. However, due to the stainless steel material, high hardness, toughness and other characteristics, in the manufacturing and processing of high difficulty, seriously affecting the mass production of stainless steel faucet, so the real 304 stainless steel faucet prices than copper prices are still high. Its characteristics are: healthy, environmental protection; product materials all use high quality 304 stainless steel, no rust, no lead, the faucet itself will not produce secondary lead pollution of water, damage to human health, can give us a healthy kitchen and bathroom living water environment.
Surface treatment of faucet
1. Chrome plating: faucet chrome plating is ** common processing method, using ** layer of copper plating acid, the second layer of nickel plating, the third layer of chromium plating three layers of electroplating process, the international standard is 8 microns, faucet plating ** high thickness of up to 0.12-0.15 mm.
Good combination of plating layer, fine adhesion, uniform color, excellent corrosion resistance, to ensure that the product surface is bright and shiny, long-lasting and new. Plating test method: after acidic 24H and 200H neutral salt spray test, no blistering, no oxidation, peeling, cracking (qualified).
2. Drawing: After electroplating nickel drawing, the product surface to form irregular lines
3. Plated bronze: electroplated bronze and then wire drawing
4.Painting, painting, porcelain baking
5. Titanium plating: the surface is as bright as gold.
Spool for faucets
The faucet spool, from $2.3 to over $10.00. Of course installed inside the faucet we can’t see the old. Cheap spool don’t say 500,000 times the switch, with a 1-2 years may leak. Now the faucet’s spool are used ceramic spool, which is characterized by; with diamond-like hardness of the ceramic spool, can withstand high temperature of 90 degrees for a long time test, the valve body pressure strength 2.5MPA.
The use of faucet water pressure requirements
General household water pressure requirements of not less than 0.05Mpa (i.e. 0.5kpf/cm) in not less than this water pressure after a period of time, such as found that the amount of water reduced, no foam nozzle, the faucet at the spout with a board hand tool gently unscrew the nets, remove impurities, generally can be restored as new.
Now the faucet bubbler has been widely concerned in the market, its advantage is that it can slow down the speed of water flow, so that the water flow to keep in 8.3 liters per minute or less to achieve the purpose of water saving.
After reading the above introduction of the faucet, we should understand why the prices of different producing areas are different. Domestic first-line brand faucets are in Kaiping outlet branding. They do not go to other places labeling is a reason. Faucet from copper to plating to accessories, each kind of almost, out of the product price is certainly not the same. Especially to use a few years later to feel the difference between the good faucet and poor faucet.
The poor faucet, a take home also looks very beautiful. But after a year, the surface of the faucet will have oxidation, and the faucet valve core will not close tightly, dripping and leaking.
The following are real cases.
To say a small detail, once the factory came to a customer, take two faucet adapters, to the factory to request processing.
Our factory director saw at a glance which is the open flat goods, which is the goods of other unknown small factory. The customer was wondering why, the factory director could tell. That’s the crux of the matter. The goods looked the same from the outside. I couldn’t figure it out at the time. After the factory manager explained to us, we understood why he could guess correctly and why some products looked the same on the outside but were very cheap.
It is not that some small factories are not good at processing, but that these factories steal materials when processing joints. The study of mechanical processing friends will be able to understand. Miscellaneous enterprise processing, interface hole inside the tapping is L-bend, that is, the right angle. And Kaiping enterprises inside the tapping is a small rounded angle. Speaking from a mechanical point of view L-bend the opening, more likely to crack, although the cost of a small rounded copper, but the quality is more secure. Of course you buy back, may use up all the same good use, maybe you will not notice this small detail.
Here is not to denigrate some manufacturers goods are not good. It’s just that different manufacturers choose different paths, some manufacturers make cheap products, but also to meet the needs of low- and middle-income people. Existence is reasonable. I hope you will buy bathroom products that you are satisfied with!
