Where is the difference between forging and casting
2023-06-09
Casting: The process of melting metal into a liquid that meets certain requirements and pouring it into a mold, then cooling, solidifying, cleaning to obtain a casting (part or blank) with a predetermined shape, size and performance. The low cost of blanks produced by casting, especially for parts with complex shapes, especially those with complex cavities, shows their economy. At the same time, it has a wide range of adaptability and good comprehensive mechanical properties.
Forging: The forging press is used to apply pressure to the metal blank to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging, as one of the two major components, can eliminate loose casting and welding holes of the metal. The mechanical properties of forgings are generally better than castings of the same material.
The difference between forging and casting is the way of production and processing.
First of all, let's talk about cast wheels. Cast wheels are made by casting molten aluminum from sand molds, cooling and forming and then machining. The forged wheel uses a steel mold, and the heated and softened aluminum block is placed in the steel mold, stamped and formed, cooled and then processed.
Forged wheels are generally printed with the word FORGED, and cast wheels have no writing on them. Cast wheels can be mass-produced. Due to the complex production process of forged wheels and the high cost of wheel manufacturing, the price of forged wheels is relatively expensive.
After the forged hub is formed, the structural molecules of the hub are relatively tight, and it can withstand relatively large pressure during use. Due to the different materials used, forged wheels are lighter than cast hubs.
The appearance of the forged wheel hub is consistent, the front and back sides are bright and smooth with good metallic luster, and the back of the cast wheel hub is dark, which can be clearly distinguished in workmanship.
Forged wheels have light weight, good heat dissipation, high strength, not easy to break after impact, high safety, low cost, simple casting hub process, and can be mass-produced.
