Zinc medal

Zinc medals are primarily made from Zinc Alloy (typically ZAMAK 3 or 5) due to its excellent fluidity for intricate 3D designs. Buyers should ensure the alloy is lead-free and nickel-free to meet international safety standards. The die-casting process should result in a smooth surface without burrs or air bubbles, providing a high-quality base for subsequent plating.

The most common finishes include Gold, Silver, and Copper plating, which can be applied in shiny, antique, or matte (sandblasted) styles. For high-end medals, ensure the supplier uses electroplating rather than spray painting to prevent peeling. A protective lacquer coating is essential to prevent oxidation and maintain the shine over long periods of storage.

For the US market, products must comply with the CPSIA (Consumer Product Safety Improvement Act), specifically regarding lead content in children's products. For the EU, REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) compliance is mandatory to ensure the absence of hazardous substances like cadmium and phthalates. Always request SGS or Intertek test reports from the supplier.

A professional manufacturer should offer Soft Enamel, Hard Enamel (Cloisonné), or Offset Printing for color application. Additionally, they should provide various attachment options such as V-stitched ribbons, sublimated lanyards, or safety pins. The ability to provide 3D mold proofs (CAD drawings) before production is a critical indicator of a supplier's technical capability.

Always request a pre-production sample (PPS) for physical approval before the mass production run. For large orders, hire a third-party inspection service to conduct a During Production Check (DUPRO) and a Final Random Inspection (FRI) to verify weight, plating thickness, and color matching against the approved sample.

Zinc medals involve a one-time mold fee, which can range from $50 to $150 depending on complexity. Negotiate to have the mold fee waived if the order quantity exceeds a certain threshold (e.g., 500 or 1,000 pieces). For long-term cooperation, use Made-in-China.com's Star Suppliers to ensure you are dealing with audited factories rather than small trading intermediaries.

Zinc is heavy; therefore, shipping costs can significantly impact the unit price. For urgent events, Air Express (DHL/FedEx) is suitable for small batches, but for bulk orders, Sea Freight (LCL) or Rail Freight (for Europe) is much more cost-effective. Ensure the supplier uses double-corrugated export cartons and individual polybags to prevent scratching during transit.

Utilize Secured Trading Services provided by reputable platforms like Made-in-China.com to protect your payment until the goods are shipped. Avoid using high-risk payment methods like Western Union for first-time transactions; instead, opt for Letters of Credit (L/C) for very large orders or Telegraphic Transfer (T/T) with a 30% deposit and 70% balance against the Bill of Lading.
