Look at the differentiated route of each production area from the technology of the faucet
According to the quality ranking of the faucet production areas in my country, the two towns of Shuikou Town, Kaiping, Guangdong, and Zhishan Town, Heshan are connected together. The next one is Nan’an, Fujian. The four major domestic faucet brands are Fujian.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.
In the brand market, 95% of Kaiping’s products used to be made for foreign orders, unlike the domestic market, because domestic orders are small and it is troublesome to manufacture. Therefore, Kaiping manufacturers have almost no major domestic brands. And why are there big brands in Foshan in China?
Because Foshan’s big brands are the market opened by mature sales channels opened by the sales of ceramic tiles. Therefore, many large companies are not very famous in China. It is said that Guangdong Kaiping faucet is good, but the key point is that Kaiping faucet electroplating process is good. The design concept is in line with the European market, and all production processes are also made in accordance with European standards. All costs and quality are high.
Leading manufacturing process
Divided into gravity casting, low pressure casting, mechanical processing welding faucet, foundry casting (not good for gravity casting), casting or welding are just different manufacturing processes, regardless of good or bad. There is a new copper alloy die-casting process, but it has a high technical content. It’s not popular yet. It is said that the cost is low and the quality is very good.
Material classification of faucet
①Brass: Brass is the most common material for faucet manufacturing. It is made of international standard H59/H62 copper. The casting adopts steel mold for gravity casting, and its wall thickness is uniform, generally 2.5-3.0 mm. Made of brass The characteristics of the faucet are: no rust, durability, anti-oxidation, and sterilization effect on water (the disadvantage is: lead is a metal that is harmful to health, and the international standard requires that the lead content in copper should not exceed 2.5%.
②Zinc alloy: a low-grade material. The density of zinc alloy is lower than that of copper, and the faucet that feels less than copper is heavier. The surface of zinc alloy is easy to oxidize from the inner wall, and white oxide powder will appear on the surface. The strength is much worse than copper. , The service life is not long, and the lead content is high. If the faucet made of zinc alloy is only 1 to two years old, it will oxidize and rot. Now zinc alloy is mainly used to make the handle of the faucet. It is made of zinc alloy die-casting. Chrome plated. Most faucet handles on the market are made of zinc alloy.
③Engineering plastics: ABS plastic faucet has the characteristics of corrosion resistance, aging resistance, no rust, lead-free, non-toxic, odorless, high pressure resistance, light weight, easy construction, and low price. It is a new type of green and environmentally friendly product. The water quality is free from the risk of rust pollution; the faucet made of plastic 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 environmentally friendly product will be used in the faucet industry It is a stimulus and should be promoted vigorously.
④Stainless steel: In the 21st century, health and environmental protection have gradually become the new themes of modern life. Stainless steel is an internationally recognized healthy material that can be implanted into the human body. Therefore, kitchen and bathroom products with stainless steel as the main material have begun to become 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 materials. Its characteristics are: Healthy and environmentally friendly; all product materials are made of high-quality 304 stainless steel, rust-free and lead-free. The faucet itself will not cause secondary lead pollution to the water source and harm human health. It can create a healthy kitchen and bathroom water environment for us .
Surface treatment of faucet
1. Chrome plating: faucet chrome plating is the most common treatment method, adopting a three-layer electroplating process of 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 faucet plating is the highest thickness It can reach 0.12-0.15 mm.
The electroplating layer is well bonded, densely attached, uniform color, and excellent corrosion resistance, ensuring that the surface of the product is bright and lasting. Electroplating detection method: after the acid 24H and 200H neutral salt spray test, there is no foaming, no oxidation Peeling, cracks (for qualified)
2. Wire drawing: Wire drawing after electroplating nickel, forming irregular lines on the surface of the product
3. Bronze plating: wire drawing after plating bronze
4. Spray paint, bake paint, porcelain
5. Titanium-plated gold: the surface is as bright as gold
Spool of faucet
The faucet spools range from 2 yuan to more than 10 yuan. Of course, we can’t see the old in the faucet. The cheap spool, let alone switch 500,000 times, may leak water after 1-2 years. Nowadays, the valve core of the faucet adopts ceramic valve core, which is characterized by: a ceramic valve core with diamond-like hardness, which can withstand a long time test of 90 degrees high temperature, and the pressure resistance of the valve body is 2.5MPA. Even in unstable water pressure The actual service life can reach more than 500,000 times when used in regions.
Water pressure requirements for faucets
Generally, the domestic water pressure requirement is not less than 0.05Mpa (ie 0.5kpf/cm). After using for a period of time under this water pressure, if the water output is found to be reduced and the water spout has no foam, it can be placed at the water outlet of the faucet Use a wrench tool to gently unscrew the mesh nozzle, remove impurities, and generally restore it as new.
Water saving of faucet
The water output of a general faucet per minute is 16kg. Now the faucet bubbler has been widely concerned in the market. Its advantage is that it can slow down the flow of water and keep the water flow below 8.3 liters/minute to achieve the purpose of saving water.
to sum up
After reading the introduction to the leader above, everyone should understand why the prices are different in different production areas. Domestic first-line brand faucets are all OEM in Kaiping Shuikou. There are reasons for them not to go to other places to OEM. From copper to electroplating to accessories, the price of the faucet is definitely different. Especially the difference between a good faucet and a poor faucet can only be felt after several years of use.
The poor faucet looks very beautiful when taken home. However, after one year of use, there will be oxidation on the electroplated surface, loose valve core of the faucet, dripping, etc.
The following is a real case:
To talk about a small detail, a customer came to the factory once, and he took two adapters from the faucet and asked for processing.
Our factory manager can see at a glance which is Kaiping and which is from other unknown small factories. The customer wondered why, the factory manager could see it. This is the crux of the problem. Things look the same from the outside. I also couldn’t figure it out. Later, as soon as the director explained, we understood why he could guess accurately, and why many products that look the same are cheap.
The factory director can see from the processing technology. It is not that some small factories have poor processing technology, but that when these factories process joints, they use the jargon to say that they steal materials. Friends who learn mechanical processing can understand. In the processing of a miscellaneous brand, the interface hole is L-bend, which is a right angle. The Kaiping enterprise is attacking small fillets. From a mechanical point of view, the opening of the L-bend is easier to crack. Although the small fillet uses copper, the quality is more guaranteed. Of course, if you buy it back, it may be equally easy to use, and perhaps you will not notice this little detail.
This is not to discredit some manufacturers for bad products. It’s just that different manufacturers choose different paths. Some manufacturers make cheap products to meet the needs of low- and middle-income groups. Existence is reasonable. I hope you can buy the sanitary products you are satisfied with!
