Faucets are those devices which are used for supplying water from a plumbing system. These devices are made of the following components: lift rod, water inlet, spout, handle, cartridge, mixing chamber and an aerator. The body of most faucets is made of brass, but zinc or chrome-plated plastics can also be used. Most residential faucets are dual control or single cartridge faucets. The system of plumbing has been in existence since the ancient times, around 1700 B. C. Since then, the plumbing system has changed drastically which has affected kitchen faucets and bathroom faucets. For several years, faucets were designed to have two handles, one for hot water and the other one for cold water. This design was changed in 1937. The main raw materials for making faucets are brass, which is an alloy of zinc and copper because it is resistant to water corrosion and calcification. In order to meet customers needs, local faucets are designed to come in a wide range of colors, finishes and styles. Some are designed to come with longer spouts and handles which are easier to operate. The manufacturing process of faucets will be affected by the shape and the finish in that some designs will be harder to forge or machine them than others. There are several finishes of kitchen faucets which include polished nickel, platinum, satin black, gold and several other colors. In addition, the consumers can customize the look of their faucets in that they can combine more than one finish. Bathroom faucets, also known as lavatory faucets are devices used for controlling the release of water to bathroom sinks. If you want to remodel your bathroom, the bathroom faucet is a key element. In order to create a stylish and unique design in your bathroom, this device is a must have. The manufacturing process for bathroom faucets and kitchen faucets has become increasingly automated in that computers are used to control most of the machines in use. Efficiency and productivity in this case have improved over the years. The main process involves making the main body of the faucet, which in some cases includes the spout if swivel is not needed, then followed by assembling the various parts then suction and finally packaging.
