DST (Dye Sublimation Transfer). It is a process that transfers color patterns to the surface of products through thermal sublimation. The surface of the transferred products is rich in color and durable. The pattern and color can be changed at any time during production; the pattern can be reversed, the surface is smooth, and has excellent scratch resistance; the production batch quantity is flexible and suitable for multi-variety batch production. It is used for products with complex surfaces. This technology can be applied to surface decoration in industries such as home appliances, beauty, games, and 3C electronics.
