Judo medal

Professional Judo medals are typically crafted from Zinc Alloy, Brass, or Iron. Zinc alloy is the preferred choice for 3D designs due to its superior fluidity and detail retention. For the finish, ensure the supplier uses electroplating (Gold, Silver, Bronze) with an anti-oxidation coating to prevent tarnishing. High-end medals often feature soft enamel or hard enamel coloring to represent the specific colors of the Judo federation or event branding.

Standard competition medals usually have a diameter between 50mm to 70mm and a thickness of 3mm to 5mm. You must verify that the ribbon attachment (V-loop or jump ring) is reinforced to withstand the weight. For official events, ensure the supplier can provide SGS or RoHS certifications to guarantee that the metal alloys are lead-free and nickel-free, complying with international safety standards for wearable awards.

Buyers should look for suppliers offering 3D relief molding to capture the intricate details of Judo techniques (like Throwing or Grappling poses). Essential customization includes laser engraving for event dates on the back, sublimation printed ribbons with custom logos, and sandblasted textures to create a premium contrast between matte and polished surfaces.

For custom medals, the mold fee is a significant initial cost (typically $50-$150). To achieve optimal cost-efficiency, an MOQ of 100 to 500 pieces is recommended to amortize the mold cost. For large-scale tournaments exceeding 1,000 units, unit prices can drop by 30-50%. Always request a pre-production sample to verify weight and color accuracy before committing to bulk manufacturing.

To ensure quality, utilize the Secured Trading Service on Made-in-China.com to protect your payment until delivery. Request a Third-Party Inspection (such as V-Trust or QIMA) to check for surface scratches, plating consistency, and weight accuracy before the goods leave the factory. Avoid suppliers who refuse to provide high-resolution photos of the actual mass production run.

Focus negotiations on mold ownership and re-order discounts. Ensure the supplier agrees to store your custom mold for at least 2-3 years for future events without charging the fee again. Additionally, negotiate Incoterms clearly; for time-sensitive sports events, DDP (Delivered Duty Paid) is often preferred to avoid customs delays, though FOB offers more control over shipping costs for experienced buyers.

Medals are heavy; therefore, shipping costs can significantly impact the total cost of ownership. For urgent event deadlines, use Air Express (DHL/FedEx), but allow a buffer of at least 10-14 days for customs clearance. For non-urgent, high-volume orders, Sea Freight or Rail Freight is much more economical. Ensure the packaging includes individual polybags and bubble wrap to prevent metal-on-metal friction damage during transit.

Always sign a Non-Disclosure Agreement (NDA) if you are providing original artwork or federation logos to prevent unauthorized resale. Conduct transactions through verified 'Audit Suppliers' on Made-in-China.com who have undergone on-site factory checks. This ensures you are dealing with a legitimate manufacturer rather than an unregulated middleman.
