The choice of base material significantly impacts the perceived value and durability. Zinc Alloy is the most popular choice for 3D designs due to its high fluidity during injection molding. Brass and Copper are preferred for high-end commemorative medals requiring struck-die precision. For budget-friendly options, Iron is common but must be treated with electroplating to prevent rust. Always verify the plating thickness (measured in microns) to ensure the finish does not peel or tarnish over time.

The process depends on your design complexity. Die Casting is ideal for multi-dimensional or hollowed-out designs. Die Striking is best for sharp, 2D high-relief details. For coloring, Soft Enamel offers a recessed textured feel and is cost-effective, while Hard Enamel (Cloisonné) provides a smooth, premium level surface that is scratch-resistant. If your design involves gradients or photos, request Offset Printing with an Epoxy coating.

Medals, especially those intended for schools or youth sports, must comply with chemical safety regulations. Ensure the products are Lead-Free and Nickel-Free to meet CPSIA (US) or REACH (EU) standards. Additionally, the neck ribbons should be tested for colorfastness to prevent staining on clothing and, in some jurisdictions, must feature a breakaway safety attachment to prevent choking hazards.

Request samples to inspect for polishing marks, air bubbles in the enamel, and plating consistency on the edges. The ribbon should be high-density polyester or nylon with a minimum width of 25mm-30mm for standard awards. Check the stitching strength at the V-join where the ribbon connects to the medal loop to ensure it can support the weight of the metal.

When ordering custom medals featuring logos or trademarks, ensure you provide proof of authorization. Conversely, verify that the supplier is not using copyrighted designs from other clients for your order. Professional suppliers on Made-in-China.com usually sign Non-Disclosure Agreements (NDAs) to protect your original artwork and molds.

Medal production involves a significant initial mold fee. To optimize costs, negotiate for a refund of the mold fee once your cumulative order volume reaches a certain threshold (e.g., 5,000 units). For recurring annual events, ask the supplier to store the mold for at least 2-3 years to avoid repeat setup charges.

Medals are high-density and heavy, making shipping costs a major factor. For orders over 100kg, Sea Freight or Rail Freight is significantly more economical than Air Express. Ensure the supplier uses double-walled corrugated cartons and individual polybags for each medal to prevent scratching during transit. Always clarify the Incoterms (e.g., FOB or DDP) before finalizing the contract.

Use secure payment methods and prioritize suppliers with Audited Supplier reports. Conduct a Pre-shipment Inspection (PSI) to verify the quantity and quality match the Proforma Invoice. Utilizing the trading security services on Made-in-China.com can provide an extra layer of protection for your payment and ensure the supplier adheres to the agreed-upon lead times.
