Zinc alloy usb drive are suitable for simple logos or patterns with clear lines. Customization of logos or images in up to 4 colors can be achieved through color printing. In addition, printing can also be done on the packaging boxes.

1. Customization for Stock Items (No Mold Required)
1. Basic Stock Item Production
Production Cycle: 1-3 days (for logo engraving or single-color screen printing only).
Process Details: Laser engraving takes approximately 2 hours per 100 pieces; screen printing requires an additional 1-2 days (including plate making).
Suitable Scenarios: Corporate events, short-term promotions, and urgent needs requiring rapid response.
2. Functional Upgrade Off-the-Shelf
Production Cycle: 3-7 days (e.g., dual interfaces, encryption features).
Dual interfaces (Type-C + USB 3.0) require an additional day for soldering and debugging. Hardware encryption modules (AES-256) require 3 days for integration testing.
2. Mold-Based Customization (New Designs)
1. Standard Mold Development
Production Cycle: 20-30 days (includes mold fabrication, sample confirmation, and mass production).
Mold Phase: Zinc alloy die-casting mold takes approximately 12 days to complete; prototyping requires 5-7 days (including plating and engraving).
Mass Production Phase: 500–2000 units require 7–10 days, with an average daily output of approximately 200 units.
2. Custom Shape Design Development
Production Cycle: 30–45 days (complex structures + specialized processes).
Example: Animal-shaped USB drives require an additional 5 days for mold detail debugging, and surface embossing processes add 3 days.

Silver: The most versatile color, offering a refined metallic matte or mirror finish after electroplating. It complements any brand style, making it suitable for both corporate logo customization and personal daily use. It features ample inventory and low customization costs.
Gunmetal (Dark Gray): Offers a more sophisticated look than silver with a subtle cool-toned metallic sheen. Ideal for business settings (e.g., bank or tech company gifts), it visually resists dirt and hides scratches well.
Gold: Primarily “bright gold” or “matte gold,” exuding inherent luxury. Commonly used for premium gifts (e.g., anniversary celebrations, client appreciation).
Black: Typically “electroplated black” or “brushed black,” featuring a minimalist, understated style. Suitable for pairing with dark packaging or tech brands, concealing minor wear, and maintaining a durable appearance over time.
Rose Gold: A trending color in recent years, featuring soft pinkish-gold tones. Primarily appeals to younger demographics or female users, commonly used for customized gifts in the beauty and fashion industries. However, the plating may show slight wear revealing the base color with prolonged use.

The primary metal finishes for custom zinc alloy USB drives refer to classic color schemes achieved through electroplating that mimic natural metallic hues. These finishes preserve the inherent texture of zinc alloy while aligning with universal aesthetic preferences for business and gifting applications.
