Round copper medal

Buyers should distinguish between pure copper, bronze, and brass. While 'copper medal' is a broad term, most high-quality medals are made of H65 or H85 brass due to its excellent balance of malleability and corrosion resistance. Ensure the thickness is at least 2mm to 5mm to provide a premium hand-feel and structural integrity. For high-end awards, verify the electroplating process (e.g., real gold, silver, or antique copper plating) and ensure a clear lacquer coating is applied to prevent oxidation and tarnishing over time.

For 2D designs with sharp lines, die-striking (stamping) is the industry standard as it offers the highest level of detail and density. If the design involves 3D relief or intricate textures, die-casting (zinc alloy with copper plating) is often more cost-effective, though a true copper medal should ideally be die-struck. For colorful designs, specify whether you require soft enamel, hard enamel (cloisonné), or offset printing with an epoxy dome. Hard enamel is the most durable and prestigious option for commemorative medals.

Since medals are often handled frequently or worn by children, they must comply with REACH (EU) or CPSIA (US) regulations regarding lead and nickel content. Ensure the supplier provides SGS or Intertek test reports confirming that the base metal and the plating are lead-free and nickel-free. Additionally, if the medal includes a ribbon, the fabric should meet OEKO-TEX Standard 100 to ensure no harmful dyes are present.

Request samples to inspect the edge smoothness; high-quality medals should have polished edges without burrs. The attachment point (jump ring or bail) must be securely soldered or integrated into the mold to prevent breakage. For the ribbon, check the stitching density and the quality of the V-seam or H-seam. A weight consistency check across a batch is also a vital KPI for quality control.

When ordering custom designs, ensure you provide proof of authorization for any logos or trademarks. Conversely, protect your own designs by signing a Non-Disclosure Agreement (NDA) with the supplier before sharing CAD files. Professional suppliers on Made-in-China.com are accustomed to IP protection protocols and can provide 'Original Design Manufacturer' (ODM) agreements to secure your creative assets.

Medal pricing is heavily influenced by mold fees and volume. For new designs, expect a one-time mold charge ranging from $50 to $150. To optimize costs, aim for an MOQ of 100–500 pieces, where the unit price significantly drops. Negotiate for free mold fees on re-orders or if the initial order exceeds 1,000 units. Always request a pre-production sample (physical or high-res photo) before authorizing full-scale manufacturing.

Copper medals are dense and heavy, making air freight expensive. For orders over 100kg, sea freight or rail transport is significantly more economical. Ensure the supplier uses double-walled corrugated export cartons and that each medal is individually wrapped in a polybag or bubble wrap to prevent scratching during transit. For urgent event deadlines, consider DDP (Delivered Duty Paid) terms to avoid customs clearance delays in the destination country.

Always conduct transactions through secured payment channels provided by reputable platforms like Made-in-China.com. Utilize Audit Reports to verify the supplier's factory location, production capacity, and business license. Avoid paying 100% upfront; a standard 30% deposit and 70% balance payment after QC inspection but before shipment is the safest industry practice.
