What is the difference between aluminum forgings and die castings? Please use a practical production case to illustrate and write an article in Chinese and translate it into English.
Aluminum forgings and die castings are both common metal processing products, but they have significant differences in production process, structural form, and application scope.
Aluminum forgings are made by compressing metal billets into various shapes under high temperature and pressure. Aluminum forgings have excellent physical properties, high mechanical strength, high temperature resistance, light weight, and strong corrosion resistance. At the same time, aluminum forgings have no pores, inclusions, shrinkage or deformation, especially suitable for producing small and high-precision parts. It is commonly used in aviation, aerospace, automobiles, machine tools, engineering machinery and other fields.
Die castings are formed by injecting molten metals into molds under high pressure to form the required products. Die castings have smooth surfaces, uniform and fine internal structure, precise dimensions, high reliability, and high production efficiency. Due to its convenience, good effect, and low cost, it is widely used in electronics, communication, transportation and other fields.
Case analysis: A certain automobile parts production enterprise needs to produce an oil tank cover. Because the oil tank cover has high requirements for shape, sealing, corrosion resistance, etc., it was decided to use die casting production after comparison. For other aluminum alloy parts produced by the company, such as engine brackets and wheel hubs, they need to bear large loads and torques, so the forging process is adopted. Through such choices, the enterprise can choose the most suitable processing technology and obtain the best economic benefits when encountering different types of parts.
