Red Punching: Advantages of Red Punching

Red stamping is a technology mainly used in metal processing, which uses universal equipment in the production process and is suitable for small and medium-sized enterprises, with high productivity and low capital investment. There are many advantages of red punch forming, and the following points are detailed below:

First, red punching is basically not limited by the shape of the product part itself. This is because the principle of punching is to press the part into the desired shape by means of extrusion plastic deformation, so it has a greater degree of freedom in shape. This flexibility makes red punching processing flexible, allowing the production of parts with standard specifications as well as parts with shaped structures.

Second, due to the core extraction device used in red punch forming, the inside of the part being pressed is hollow. This is different from the part processed by the forging die. The burr thickness of forged parts is usually more than 2 mm, so the burr thickness of red punch forming is only about 0.5 mm, and the material utilization rate is much higher than that of the forging die. This design also makes the internal structure of the machined part more robust, thus improving mechanical strength and corrosion resistance.

Third, the mechanical properties of red punch forming are good. After punching, the metal blank is heated, extruded and cooled so that the internal crystal structure of the part becomes more uniform in shape from the inside to the outside of the part in a linear fashion. This eliminates the original defects produced by processes such as casting or drawing and makes the mechanical properties of the part improved.

Fourth, red punch forming is suitable for processing various non-ferrous or ferrous metals. Whether it is brass, aluminum alloy, stainless steel, carbon steel and other various materials, all of them can be processed by the red punch forming process. Therefore, red punch forming has sufficient applicability and wide application prospects.

In conclusion, the advantages of red stamping include its production using universal equipment, ease of production, high productivity, low cutting volume, suitability for mass production, and the ability to improve the mechanical strength and corrosion resistance of parts. Such superiority makes red stamping widely used in many manufacturing industries, and it has become one of the mainstream technologies. The development of this technology is promising and the application prospects are promising.

1, red punch forming is basically not limited by the shape of the product parts themselves;

2, production using common equipment, easy to produce, suitable for small and medium-sized enterprises;

3, high productivity, suitable for mass production;

4, due to the use of core extraction device, the internal part of the pressed part is hollow, unlike the part processed by forging die, the internal is solid, the general burr thickness of small punching die is about 0.5mm, while the burr thickness of the parts of forging die is generally above 2mm, so the material utilization rate is much higher than that of forging die;

5、Red punching is a process with little cutting and no cutting. Surface roughness close to the surface roughness of the die, dimensional accuracy can reach 6-7, so the amount of mechanical cutting is very small;

6, the mechanical properties of good. After punching the die, the metal blank is heated, extruded and cooled, and its metal structure is changed, eliminating the original defects caused by casting or drawing, so that the internal crystal structure of the part is improved from the inside to the outside of the linear shape Mechanical properties of red punched parts;

7, after punching, the internal grain of the metal is refined, thus increasing the density of the metal and improving the corrosion resistance of the parts;

8、It is suitable for processing various non-ferrous or ferrous metals.

Since the punching process requires less capital, high production efficiency, high quality parts and is suitable for mass production, it has produced good economic benefits. For example, the punching process has been widely used in the production of daily hardware industry, such as various valves, pipe fittings, nuts, etc. In the pipe fittings made of copper punching, with its unparalleled quality advantages, has replaced the products produced by die-casting or casting in the past.
