Case parts made of sheet metal

　　What are the technical requirements for the case parts made of sheet metal？
　　①The case made of sheet metal should have good technical performance. For example, the structure of the power cabinet should be designed physically and chemically according to the requirements of the electrical and mechanical properties and the use environment of the equipment, so as to ensure that the structure of the hardware cabinet shell has good stiffness and strength, as well as good electromagnetic isolation, grounding, noise isolation, ventilation and heat dissipation. In addition, the shell of the hardware case shall be vibration resistant, impact resistant, corrosion-resistant, dust-proof and radiation-proof, so as to ensure the stable and reliable operation of the equipment。
　　②The case parts of sheet metal manufacturing should have good usability and protective facilities, which are easy to operate, install and maintain, and can ensure the operator。
　　③The case made of sheet metal should be convenient for production, assembly, debugging, packaging and transportation。
　　④The case parts made of sheet metal should meet the requirements of standardization, standardization and serialization. ⑤ The shape of sheet metal shell is beautiful, applicable and color coordinated。
　　The case shell is divided into two basic structures: profile and sheet。
　　①There are two kinds of case parts: steel case and aluminum case. The shell of steel case is composed of special-shaped seamless steel pipe as column. This kind of case shell has good rigidity and strength, and is suitable for heavy equipment. The case shell composed of aluminum alloy profiles has the rigidity and strength, which is suitable for general or light equipment. The case is light in weight, less in processing, beautiful in appearance and widely used。
