What does red rush mean?

What does red rush mean? Introduction is as follows:

"Red punching" is actually a hot extrusion process, because in Zhejiang coastal manufacturing industry, especially pipeline hardware production industry, if someone talks about "hot extrusion", not many people can immediately notice its meaning. If the word "red punch" is mentioned, then people in the industry will know what kind of process this is. What kind of mold? What kind of products are produced? In addition, because the name "red rush" is closer to the actual treatment and louder than other names, it is easy to be accepted.

"Hongchong" is a new term, and it is difficult to find its source in the dictionary. Because the red punching process is an advanced professional process just developed on the basis of modern precision forging and hot extrusion. With the progress of society and the development of science and technology, the mechanical industry has put forward new mechanical strength requirements for mechanical parts. There are generally two ways to improve mechanical strength, one is to change the material of the part, and the other is to change its processing method.

Red stamping process is one of the effective methods to improve the mechanical properties of parts by changing the processing method, so it has strong vitality and good development prospects as forging process. The process of red stamping is like precision forging, which heats the metal blank and forms it in the mold. However, except for large-scale red stamping parts, red stamping is generally formed at one time, while precision forging is generally formed by multiple times.

Compared with hot extrusion, the red stamping process also needs to heat the metal blank, and the hot extrusion die is basically the same as the cold extrusion die. The flow of metal material in the die cavity is relatively simple, the shape of the formed part is almost the same as that of the cold extrusion part, and the structure of the red punching die is more complicated than that of the hot extrusion die. Its structural feature is that the stamping method is organically combined with the molding method of the cavity mold, which can not only extrude the cavity extrusion mold on the press,

Moreover, the multi-directional demoulding action can be carried out at one time, and the metal material is forced to flow in the mold cavity through complex flow under strong enough pressure, and the complex parts in the shape of the imaging cavity mold (injection mold) are extruded. Therefore, the red punching process is a deeper and wider development of precision forging and hot extrusion process.
