Notebook computers and PAD products, using metal casings, and sandblasting and oxidation technology for surface treatment have become the mainstream technology used by manufacturers in the industry. The lightweight metal material is used as the outer square meter of the notebook computer, and its protective performance, heat dissipation performance and high-end appearance and texture have outstanding advantages.
