Medal with sublimation ribbon

When sourcing medals, the base material determines the weight, perceived value, and durability. Zinc Alloy is the most common choice for 3D designs due to its excellent fluidity during die-casting. For premium awards, Solid Brass or Copper offers a heavier feel and superior plating finish. Ensure the supplier uses Eco-friendly plating (nickel-free/lead-free) to comply with international safety standards like EN71 or CPSIA.

The ribbon should be made of High-Density Polyester to ensure a smooth surface for heat transfer. Check for a GSM (Grams per Square Meter) of at least 150-200 to prevent transparency. The sublimation printing must show vibrant colors and sharp edges without bleeding. Crucially, verify the colorfastness rating (Grade 4 or higher) to ensure the design does not fade when exposed to sweat or sunlight during outdoor events.

The connection point is a common failure zone. Specify a Jump Ring or V-sewn attachment that can withstand a pull test of at least 5-10kg. For sublimation ribbons, a continuous loop (V-stitch) is preferred over simple clips for a professional look. Ensure the ribbon width (typically 20mm, 25mm, or 38mm) matches the medal's loop size to prevent bunching or excessive sliding.

Beyond the ribbon, the medal itself can feature Soft Enamel, Hard Enamel, or Sandblasting effects. For complex logos with gradients, ask for Offset Printing with an Epoxy Dome. If you require rapid prototyping, inquire if the supplier offers 3D Mold Rendering before physical mold carving to save on revision costs and time.

When providing custom logos or event branding, ensure you have the Authorization Letter for the artwork. Conversely, protect your own designs by signing a Non-Disclosure Agreement (NDA) with the supplier. On Made-in-China.com, prioritize Audited Suppliers who have a verified track record of producing licensed merchandise to avoid customs seizures.

Medals are weight-heavy items; therefore, Unit Price is highly sensitive to raw material (Zinc/Copper) market fluctuations. Negotiate a fixed price for a 3-6 month window if you have recurring events. For lead times, always factor in a 10-14 day buffer for custom mold creation and 7 days for air freight. Request a Pre-production Sample (PPS) to be approved via high-resolution video or physical mail before the mass production clock starts.

Due to the high weight-to-volume ratio, Sea Freight (LCL) is the most economical for orders over 500kg. However, for time-sensitive sports events, International Express (DHL/FedEx/UPS) is safer. Ensure the supplier uses Individual Polybags and Double-Wall Corrugated Cartons (K=K) with inner dividers to prevent the medals from scratching each other during transit.

Use Secured Payment services provided by professional platforms to ensure funds are only released upon proof of shipment. For large orders, hire a Third-Party Inspection (TPI) service to conduct a Random Sampling Inspection (AQL 2.5/4.0) at the factory to check for plating bubbles, enamel overflow, and ribbon print alignment before final payment.
