Faucet 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. Now there is a new copper alloy die-casting process developed by the leader, 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 a common material for faucets made of faucets. 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 faucet is characterized by: no rust, durability, anti-oxidation, and has a sterilization effect on water.
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 that of copper. , The service life is not long, and the lead content is high. If the water** made of zinc alloy is only 1 to two years old, it will oxidize and rot. Now zinc alloy is mainly used to make water** handles. It is made of zinc alloy die-casting It is made and then chrome-plated. Most of the ** handles on the market are made of zinc alloy.
③Engineering plastics: ABS plastic water** has the characteristics of corrosion resistance, aging resistance, no rust, lead-free, non-toxic, odorless, high pressure resistance, light weight, easy construction, low price, etc. It is a new type of green environmental protection 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 green and environmentally friendly product is in water** It will be a kind of urging trend in the industry 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 material, it is difficult to manufacture and process, which seriously affects the mass production of stainless steel**. Therefore, the price of real 304 stainless steel** is higher than that of copper. Its characteristics Yes: 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, harm human health, and create a healthy kitchen and bathroom life for us Water environment.
Surface treatment of faucet
1. Chrome plating: faucet chrome plating is a common treatment method for faucets. It adopts a three-layer electroplating process of acid copper plating on the faucet layer, nickel plating on the second layer, and chrome plating on the third layer. The international standard is 8 microns, and the thickness of the faucet electroplating faucet can reach 0.12. -0.15 mm.
The electroplating layer is well combined, densely attached, uniform color, and corrosion-resistant faucet to ensure that the surface of the product is bright and lasting. Electroplating detection method: after the acid 24H and 200H neutral salt spray test, no blistering, no oxidation, peeling , Crack (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
The spool of the faucet
Faucet spools, from 2 yuan to 3 yuan to more than 10 yuan. Of course, we can’t see it 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: the ceramic valve core with diamond-like hardness can withstand the test of 90 degrees high temperature for a long time, and the pressure resistance of the valve body is 2.5MPA. Even in unstable water pressure For regional use, the actual service life can still reach more than 500,000 times.
Water pressure requirements for the use of 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 to remove impurities, and generally it can be restored as new.
Water-saving faucet
A general faucet has a water output of 16kg per minute. 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.
Summarize
After reading the introduction to the leader above, everyone should understand why the prices in different production areas are different. Domestic first-line brand faucets are all OEM in Kaiping Shuikou. There is a reason 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 you take it home. But after one year of use, there will be oxidation on the electroplated surface, loose valve core of the faucet, dripping and so on.
