Custom hard enamel keychains are made through a precise multi-step process.
First, your design is stamped or die-cast into a metal base (usually zinc alloy or iron), creating raised metal lines and low areas (Molding).
Next, colored resin is filled into these low areas by hand (Coloring). Then, the keychains are baked in a high-temperature oven to harden the colors (Baking).
Finally, the surface is carefully polished until it is completely flat and even with the metal lines. The base is then plated with your chosen finish like gold or silver, creating the smooth, jewelry-like look that hard enamel is famous for (Polishing & Plating).

Our custom hard enamel keychains start as low as $1.48, with prices changing based on your size, design, and order quantity. As a professional keychain manufacturer, we offer the best factory-direct wholesale rates for your custom enamel keychain projects.

You can choose from 4 premium metal plating finishes for free: Shiny Gold, Shiny Silver, Shiny Copper, or Black Nickel. For the enamel colors, we use standard Pantone numbers to match your artwork perfectly. This ensures your custom hard enamel keychains always have a clean, high-end, jewelry-grade look.

To ensure your final keychain perfectly matches your vision, please provide the following documentation: Vector File Formats: We highly prefer .AI, .PDF, or .EPS files. Vector files allow our production team to scale your design perfectly without any loss of quality.
Color Codes: Please specify your colors using the Pantone Matching System (PMS). This guarantees that the liquid enamel colors mixed in our factory exactly match your brand's colors.
Line Thickness Note: Ensure that the metal lines separating your colors are at least 0.2mm thick so the metal mold can be formed successfully.

Size Options: We offer 9 standard sizes based on the longest side of your design: 1" (25.4mm), 1.25" (31.8mm), 1.5" (38.1mm), 1.75" (44.5mm), 2" (50.8mm), 2.25" (57.2mm), 2.5" (63.5mm), 2.75" (69.9mm), and 3" (76.2mm). If you are not sure, you can just click "Recommended Size".

Standard Thickness: Our keychains are generally 3.0mm thick. This thickness is very strong, does not bend easily, and feels heavy and high-quality in your hand.

Smooth Surface: Hard enamel is polished until the surface is completely flat with the metal lines. There is no bumpy feeling, giving your custom hard enamel keychains a high-end, jewelry-like smooth look.
Long-Lasting Quality: Hard enamel goes through more baking and polishing steps. This makes the metal hard enamel keychain highly scratch-resistant, durable, and it will not fade over time.
Premium Metal Look: It works perfectly with shiny metal plating like gold or silver. As a professional keychain manufacturer, we highly recommend hard enamel to turn your custom artwork into clean, luxury-style retail merchandise.
