The electronic equipment shell is a precision-engineered enclosure with dimensions of 30x150x220mm, constructed from durable materials such as cold-rolled sheet (SPCC), hot-rolled sheet (SHCC), galvanized sheet (SECC, SGCC), aluminum, and stainless steel plates. Designed with a precision tolerance of 0.05mm, the shell is manufactured using advanced processing techniques, including laser cutting, stamping, bending, and riveting. To ensure superior surface quality, durability, and aesthetics, it undergoes specialized treatments such as sandblasting, spraying, anodizing, plating, laser engraving, silk screening, and pad printing. These processes guarantee reliability and visual appeal, meeting the requirements of modern electronic applications.
