How to Produce: About Faucets
Every household needs to install faucets to ensure our living water, so do you know how kitchen faucets and bathtub faucets are produced?
What materials are needed to produce the main body of the faucet?
1. Brass
Brass material faucets made of good quality, novel style, high price, and low lead content, are the most popular mainstream products sold in the market.
2. Zinc alloy
Zinc alloy material faucets made of general quality, style, and cheap, are the main product of the low-end sales market.
3. Stainless steel
Stainless steel faucets made of good quality, style changes, and low lead content, are one of the most popular products in recent years.
4. Plastic
Plastic material faucets with a certain degree of beauty, are affordable, but the use of short life, especially in outdoor use is very easy to age.
What steps are needed to produce kitchen &bathroom faucets?
1. Product design
The faucet designer designs a beautiful product.
2. Mold making
The designer designed the product to make a suitable mold.
a. Casting
The manufacturing process of the main body of the faucet is sand casting, manual metal mold casting, gravity casting machine, and low-pressure casting four categories, through one of the processes to create the faucet embryo, and after casting cleaning as well as casting product inspection.
The low-end faucet is sand casting, also known as sand casting. This production process casting faucet structure will be relatively sparse, very easy to form trachoma and porosity, and product quality is difficult to ensure.
The high-end faucet is gravity casting, this production process casting faucet internal structure is tight, the quality of the product than the sand casting well. A more advanced faucet is using die-casting, that is, a one-time pressure grinding molding.
What is the sand turning process like for a regular faucet?
Sand mold casting: the casting method of compact molding with sand. With a variety of shapes, sizes and a variety of commonly used alloy castings for the production of equipment investment is small, raw materials are easy to obtain and inexpensive.
Sand casting is a kind of sand as the main modeling material, the production of casting the traditional casting process. Sand casting is generally used in gravity casting, with special requirements can also be used in low-pressure casting, centrifugal casting and other processes.
Sand casting adaptability is very wide, small pieces, large pieces, simple pieces, complex pieces, single pieces, large quantities can be used. Sand casting molds, used to be made of wood, commonly known as wood mold.
Later, the casting factory to change the wooden mold easy to deformation, easy to damage and other shortcomings, in addition to single piece production of sand castings, all changed to higher dimensional accuracy, and longer service life of aluminum alloy molds or resin molds.
Although the price has increased, but still cheaper than metal casting molds, in small quantities and large production, the price advantage is particularly prominent. In addition, the sand type than the metal type fire resistance is higher, so such as copper alloys and ferrous metals and other materials with high melting points are also used in this process.
However, sand casting also has some shortcomings: because each sand casting can only be poured once, get casting casting that is damaged, must be re-modeling, so the production of sand casting teach rate is low.
And because of the overall nature of the sand is soft and porous, so the sand casting castings lower dimensional accuracy, the surface is also rougher, however, modern technology has greatly improved the surface condition of the sand castings, the effect of polishing can be comparable with the metal castings.
It is worth noting that a variety of chemical bonded sand flourished, clay wet sand is still the most important modeling material, its wide range of application, consumption of large, is any other modeling material can not be compared with it.
“Sand casting” when the first half-type on a flat plate, put the sand box to fill the sand to tighten and scrape flat, under the type of manufacturing is complete, will create a good sand mold turned 180 degrees.
Put the upper half-type, sprinkle the parting agent, put on the sand box, fill the sand and tighten and scrape flat, will be on the sand box turned 180 degrees, respectively, take out the upper and lower half-type, and then the upper type turned 180 degrees and the lower model Combined, sand molding is completed, waiting for casting.
This process is commonly known as “sand turning”.
Sand turning is a production method in which molten metal is poured into the casting cavity and cooled and solidified to obtain a product. In the faucet manufacturing process, cast iron is used to make blanks, and sand molding is usually used to manufacture cast iron parts. The raw material of sand mold is mainly sand, and mixed with binder, water and so on.
The sand molding material must have a certain bonding strength in order to be molded into the desired shape and to be able to withstand the washout of hot copper water without collapsing. In order to create a cavity within the sand mold that matches the shape of the casting, a model must first be made from wood, called a wood mold.
The volume of the hot copper water will shrink after cooling, therefore, the size of the wooden mold needs to be increased according to the shrinkage rate on the basis of the original size of the casting, and the surface that needs to be cut and processed is thickened accordingly. Hollow castings need to be made of sand core and the corresponding core wooden mold (core box). With a wooden mold, you can turn the cavity sand mold.
In the manufacture of sand mold, to consider how to separate the upper and lower sand box in order to take out the wooden mold, but also to consider where the copper water from the inflow, how to fill the cavity in order to get a good quality castings.
After the sand mold is made, it can be poured, that is, the copper water is poured into the cavity of the sand mold. Then there are also sand removal, repair, polishing and other processes, to become a qualified faucet body.
Sand casting has a long history and is the most widely used process. Speaking of long history, can be traced back to thousands of years ago; on the scope of its application, it can be said that there is no place around the world do not use.
b.Finishing
Faucet embryo after all kinds of machine tools for its turning, milling, planing, grinding, boring, and other types of machining, in order to achieve precision, and tolerance inspection.
c.Polishing
After finishing the faucet needs to be polished, first to burr, then need to first rough polishing and then fine polishing, followed by over sand and then repair the light version, you get a mirror gloss faucet body.
d. Electroplating
The polished body needs to be plated with copper first to enhance the adhesion of electroplating, and then plated with a nickel layer (including semi-bright nickel and bright nickel) nickel layer plays the role of corrosion resistance, and because nickel itself is a soft material and dark color, so the last will be plated with a layer of chromium layer on the nickel layer to play a role in hardening the surface while improving the brightness.
e. Prepare the whole set of product assembly accessories
Handle, handle screws, red and blue beads, spool, pressure cap, half circle, bend, O-ring, outlet, bubbler, outlet gasket, bottom ring, bottom ring gasket, sleeve right angle, sleeve gasket, sleeve nut, braided tube, cotton bag, color box, outer box. Assemble into a complete set of kitchen faucets on the assembly line.
f. After the faucet is assembled
it needs to go through a machine pressure test and water test, and after the finished product is inspected, the packaging is completed and finally shipped to consumers all over the world. You can use the new faucet in the bathroom with water supply lines. It can make you homeowners save water. You can use a soap dispenser if you want clean bathroom sink faucets.

What steps are needed to produce faucet parts?
1. Faucet cartridges
There are many kinds of material of the cartridge, the most used is still stainless steel cartridge or ceramic cartridge. cartridge is used to adjust the water flow speed and size of the faucet, is an important component of the faucet.
Through professional production equipment to produce. cartridge shell inserted with a rotary core, the lower end of the rotary core through the fork stuck in the valve piece, the valve piece and the static valve piece fit each other, the static valve piece is fixedly mounted in the cartridge shell.
In the static valve piece is also mounted below the pressure piece and the gasket, the static valve piece on the opening of the two opposing inlet holes, the valve piece with the inlet holes corresponding to the outlet holes, the rotary core on the opening of the through-hole and its center axis in the same direction.
2. Braided tube
Braided tube is used to enter the water out, generally with 50 cm long braided tube, braided material there are many kinds of, of which the quality of a little better to belong to the stainless steel braided tube, the quality of aluminum wire braided tube is a little worse.
The wire is first braided around the inner core so that the wires cross each other to form a braid, and then the braid is heated and shaped and removed from the core to obtain a braided tube.
Due to the wire in the weaving in the tensile state, heat shaping of the braided body in the role of wire tension tightly wrapped around the surface of the inner core, resulting in the two are difficult to separate, if not properly operated will destroy the structure of the braided tube, reducing the yield of manufacturing.
3. Hose
The hose is used to connect the water out of the shower, usually with 1.5 meters of hose, the hose has a variety of materials:
1)PVC hose is rich in color, good quality and high price.
2)Stainless steel hose with stable quality and affordable price, most products are equipped with stainless steel hose.
3)Nylon hose, most of the pull-out faucet is mostly used nylon hose.
4. Installation of accessories
1) Horseshoe piece: Horseshoe piece is divided into single-pole horseshoe piece and double-pole horseshoe piece, with copper, stainless steel, iron and so on.
2) Installation sleeve: the upgraded version of horseshoe piece, easier to fix the installation parts.
3) Angle: the angle is mainly applicable to the connection of shower faucet, bathtub faucet and water pipe.
4) Wall cover: decorate the threads of shower faucet, bathtub faucet and water pipe connection, make the faucet more beautiful.
