What does the red flush of the red triangle valve mean?
6) mechanical properties of the red, because red after the metal after heating, extrusion, cooling, the metal structure changes, to eliminate the defects due to the original casting or drawing parts caused by the internal crystal structure is from the inside to the outside line, improve the mechanical properties of red parts; 7) the red after the internal metal parts, the grains were refined and enhanced the density of metal parts, improve the ability to resist;8) apply to all kinds of colored or black metal processingBecause the red technology investment, high production efficiency, product quality, and is suitable for mass production, resulting in a good economic effect. For example, red in the daily hardware industry in the production process, has been widely used, such as all kinds of valves, pipe hardware with red copper. Pipe fitting, nut etc., to the quality of its unparalleled advantage, has replaced the past has been used in die casting or casting production.Red washed, generally in Zhejiang's manufacturing industry, especially in the pipeline hardware production industry, used in a wide range of terms
3) high productivity, suitable for mass production;4) due to the core pulling device, the internal part is pressed out of the hollow, not forging processed parts as internal is solid, and the thickness of small red flash dies in about 0.5mm, and the thickness of mold forging burr is higher than 2mm, so the material utilization rate is much higher than the forging die;5) red stamping is a kind of machining process without less cutting. The surface roughness is close to the mold and the dimension accuracy can reach 6-7 grade. Therefore, its mechanical cutting is very small;
"Red rush" is a new term, and its name can not be found in the dictionary, because the red stamping process is an advanced professional process developed from the modern precision forging and hot extrusionIn addition, the name of "red punch" is closely related to the actual processing and is more easily accepted than other namesThe advantage of the red stamping process) 1) the forming is basically free from the external shape of the part of the product;2) production and use of common equipment, production is easy, suitable for small and medium enterprises production;
