Metal key USB drives can feature multi-layer gradient screen-printed logos, but this technique is only suitable for glossy or polished metal surfaces. Brushed finishes are not compatible with gradient printing. Additionally, logo designs should not be overly complex, and color palettes should be kept minimal to ensure optimal print quality.
Laser Engraving Fee: ¥0.20 per side, no additional plate-making charges.
Screen Printing Fee: ¥1.00 per unit (includes automated equipment setup costs), plus ¥100 per design for screen plate creation.
The USB 3.1 interface (including Gen1 and Gen2 standards) is compatible with the structural design of metal key USB drives. There are no technical barriers to implementing the USB 3.1 interface (with transfer rates up to 5Gbps/10Gbps) in metal key USB drives.
The core challenge lies in matching the controller chip with the interface module. Mainstream USB flash drive controller chips (such as Phison’s PS2251-17 and Silicon Motion’s SM3281) all support the USB 3.1 protocol and can be directly integrated onto the circuit board of a metal key USB flash drive. Furthermore, the physical dimensions of the interface are identical to those of USB 3.0/3.2, eliminating the need to modify the key-shaped casing structure.
