China's faucet origin, according to quality rankings, Guangdong Kaiping Shuikou Town Heshan site Shanzhen two towns are linked together, down is Fujian Nanan, the domestic four major brands of faucet is Fujian, Jiumu, Zhongyu, brilliant, Shenlu. The rest is Wenzhou, Zhejiang. Kaiping also has more famous brands. But why are the leading four brands in Fujian? For example, the content of copper, Kaiping than in Fujian, Zhejiang high content....
In the brand market, 95% of the products of the previous Kaiping were orders from foreign countries, unlike the domestic market, because domestic orders were small and the manufacturing was troublesome. Therefore, there are almost no big brands in Kaiping. Why is there a big brand in Foshan?
Because Foshan's big brand is opened by mature marketing channels opened by the sales of tiles. Therefore, many large companies are not well-known in the country. It is said that the Kaiping faucet in Guangdong is good, but in fact there is a key point is the Kaiping faucet plating process is good. The design concept is in line with the European market, and all production processes are also done according to European standards. All costs and quality are high.
Faucet manufacturing process
Gravity casting, low pressure casting, machining welding faucets, sand casting (no gravity casting), casting, or welding are just different manufacturing processes, regardless of quality. There is now a new copper alloy die-casting process, but with high technological content. Not yet universal. It is said that this kind of cost is low and the quality is very good.
Water tap material classification
1 Brass: Brass is the most common material for faucet manufacture. It is made of international standard H59/H62 copper. It is cast by steel die for gravitational casting. Its wall thickness is uniform, generally 2.5-3.0 mm. Made of brass. The characteristics of the taps are: no rust, durability, anti-oxidation, bactericidal 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 shall not exceed 2.5%.
2 Zinc alloy: low-grade materials, zinc alloy density is less than copper, copper faucet does not feel heavy, from the inner wall to see the surface of zinc alloy is easily oxidized, the surface will appear white oxide powder. 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 oxidized and rotted in only one to two years, the zinc alloy is mainly used for manufacturing faucet handles. It is made of zinc alloy die-casting, and then Chrome plated. Most of the faucet handles in the market are zinc alloy.
3 Engineering Plastics: ABS plastic faucets are corrosion resistant, anti-aging, non-rust, lead-free, non-toxic, odorless, resistant to high pressure, light weight, simple construction, low price, etc. It is a new type of green environmental protection product. The danger of rust-free water pollution; the taps made of plastics are non-toxic, non-polluting, compact in shape, simple and convenient to install, and in line with national drinking and drinking water standards. This green product will be used in the faucet industry. It is a kind of impetus that should be vigorously promoted.
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 health material that can be implanted into the human body. Therefore, kitchen and bathroom products made of stainless steel have 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 taps. Therefore, the price of genuine 304 stainless steel taps is even higher than that of copper. Its characteristics are: Health, environmental protection; All materials use high-quality 304 stainless steel, no rust, no lead, the lead itself will not produce secondary lead pollution on the water, damage people's health, can give us a healthy kitchen and bathroom life water environment .
Faucet surface treatment
1. Chrome plating: The chrome plating of the faucet is the most common treatment method. The first layer of copper plating, the second layer of nickel, the third layer of chrome plating three-plating process, the international standard is 8 microns, the maximum thickness of the faucet plating up to 0.12 -0.15 mm.
The electroplating layer has good bonding, fine adhesion, uniform color, excellent corrosion resistance, ensuring the shiny and bright surface of the product, and long-term constant. Electroplating detection method: After the acidic 24H and 200H neutral salt spray test, no foaming, no oxidation, Peeling, crack (for qualified)
2. Brushed: Brushed nickel plating, the product surface to form irregular lines
3. Plated bronze: brushed copper after plating
4. Spray paint, paint, porcelain
5. Titanium-plated gold: shiny golden surface
Spool of valve
Leading valve core, from 2 blocks of 3 dollars to more than 10 dollars. Of course, we can't see the old in the faucet. The cheap spool does not say 500,000 switches, and it may leak for 1-2 years. Now the valve core of the faucet adopts the ceramic valve core, which is characterized by: The ceramic valve core with diamond-like hardness can withstand the long-term test of high temperature of 90 degrees, the pressure strength of the valve body is 2.5MPA. Even if the water pressure is unstable Regional use, the actual service life can still reach more than 500,000.
Tap water pressure requirements
The general household water pressure requirement is not lower than 0.05Mpa (ie 0.5kpf/cm). After using for a period of time not lower than this water pressure, if the water volume is found to be reduced and there is no foam at the outlet nozzle, it can be at the water outlet of the faucet. Gently unscrew the net nozzle with a wrench to remove impurities and generally recover as new.
Water saving faucet
The average tap water output per minute is 16kg. Nowadays, the faucet bubbler has been widely studied in the market. Its advantage is that it can slow the flow of water and keep the water flow below 8.3 liters/minute to save water.
to sum up
After reading the above introduction to the leader, we should also understand why the prices in different production areas are different. Domestic first-line brand faucets are all branded at Kaiping outlets. There is a reason why they do not go to other places for branding. Faucets range from copper to electroplating to fittings. For each type of product, the price of the product is definitely not the same. In particular, it takes a few years to feel the difference between a good faucet and a bad faucet.
The poor leader, when taken home, looks very beautiful. However, after one year, the surface of the plating will be oxidized, and the tap valve core will not be closed tightly.
The following is a real case:
Speaking of small details, a customer came to the factory and took two leading mixers to the factory for processing.
Our manager at a glance saw which was Kaiping, which is the goods of other unknown small factories. The customer is wondering why the director can see it. This is the key to the problem. Things look the same from the outside. I could not think of it at the time. Later, the director explained that we understand why we can guess why he can guess and why many products that look the same are very cheap.
The director is aware of the processing technology above. It is not that some small factories do not process well, but these factories use the jargon to say that they are stealing materials when processing joints. A friend who learns mechanical processing will understand. No-name companies processing, the interface hole is attacked inside the L-bend, which is right-angled. The Kaiping company attacked the small rounded corners. From the mechanical point of view, the opening of the L-bend is easier to crack. Although the small fillets cost copper, the quality is more secure. Of course, if you buy it back, it may be as easy to use. Maybe you will not notice this small detail.
It is not a bad idea to dismantle certain manufacturers here. Just different manufacturers choose different ways, some manufacturers make cheap products, but also meet the needs of low-income people. Existence is reasonable. I hope you can buy your own sanitary products!
