Product Information：
This Bib Tap Valve is one of the R series taps. The model is R09. The raw material is CW617 brass. It can be called Bibcock or Water Tap.
The biggest feature of this Bib Tap Valve is similar to Bibcock R07. They all have a unique shape, special shape, smooth body, that is, disassembly and assembly, which is very convenient for disassembly and assembly. But this Bib Tap Valve and Bibcock R07 also have certain differences in appearance. The difference between the faucet and faucet of the two can be clearly seen.

Product Features:
"Hong Chong" is a new term, and the source of its name cannot be found in the dictionary. Because the red punching process is an advanced professional process that has just been developed on the basis of modern precision forging and hot extrusion. In addition, the name "Red Chong" is more closely related to the actual processing and is louder than other names, so it is easy to accept.
Advantages of red punching process:
Forming is basically not limited by the external shape of the product parts; production uses common equipment, easy to put into production, suitable for small and medium-sized enterprises production; high productivity, suitable for mass production; due to the use of core-pulling device, the inside of the pressed part is hollow Yes, the parts processed by the forging die are not solid inside, and the thickness of the burr of the small red die is about 0.5mm, while the thickness of the burr of the forging mold is generally more than 2mm, so the material utilization rate is better than that of the forging die. Much higher; red punching is a machining process with little and no cutting. The surface roughness is close to that of the mold, and the dimensional accuracy can reach 6-7, so its mechanical cutting volume is very small; the mechanical properties of the red punch are good, because the red punch After the metal blank is heated, squeezed, and cooled, its metal structure changes, eliminating the original defects caused by casting or drawing, making the internal crystal structure of the part linear from the inside to the outside, and improving the red stamping part. The mechanical properties of the parts after red punching, the internal grains of the metal have been refined, the density of the metal has been enhanced, and the corrosion resistance of the parts has been improved; it is suitable for various colored or black metal processing.
Because the red punching process requires less capital, high production efficiency, good quality of parts, and suitable for mass production, it has produced good economic effects. For example, the red punching process has been widely used in the production of daily hardware industry, such as various valves, pipe joints, nuts, etc. in the pipe hardware made of copper red punching, with its unparalleled quality advantages. , Has replaced the products that have been produced by die casting or casting in the past.
Red punch production process:
Copper ingot→dissolving→casting (low-grade casting with sand casting, high-quality faucet with gravity casting)→cleaning after casting→casting inspection→mechanical→tolerance inspection→grinding→surface inspection→plating→plating inspection→assembly→test pressure→finished product inspection→Packing→Factory.
Casting: low-end casting is made with sand casting, high-quality faucets are made with gravity casting, and the relatively new technology is die-casting. One-time pressure grinding is similar to the current zinc alloy die-casting process.
