Advantages of hot forging
➤ 1. Forming is basically not restricted by the external shape of product parts.
➤ 2. production and use of common equipment, easy production, suitable for small and medium enterprises production;
➤ 3. High productivity, suitable for mass production;
➤ 4. Because of the use of the core pulling device, the inside of the pressed parts is hollow, not as solid as the part produced by the forging die, and the thickness of the edge of the general small hot forging die is about 0.5mm, and the thickness of the blank of the forging die is generally above 2mm, and the utilization ratio of the material is much higher than that of the forging die.
➤ 5. Hot extrusion is a kind of machining technology with little cutting. The surface roughness is close to the mold, and the dimension accuracy can reach 6-7, so its mechanical cutting capacity is very small.
➤ 6. The mechanical properties of hot extruded parts are good because the metal structure of the metal blank after hot extrusion is changed after heating, extruding and cooling. The defects caused by casting or drawing are eliminated, and the internal crystal structure of the parts is from inside to outside, which improves the mechanical properties of the hot forging parts.
➤ 7. After hot extrusion, the grain inside the metal is refined, which enhances the density of the metal and improves the corrosion resistance of the parts.
➤ 8. It is suitable for all kinds of colored or black metal processing.
