What is the introduction to the NCVM process for the middle frame of the Xiaomi Smart Band 8?

Using NCVM surface treatment technology, the product surface does not have conductivity. Its surface layer is insulating material, the middle layer is metallic luster material, and the bottom surface is colored material. Lightweight is one of the characteristics of band products. The middle frame adopts NCVM technology, which not only ensures the lightweight of the band, but also has a delicate metallic texture. At the same time, wearing it in a low-temperature environment will not give you a metallic chill.
