Wholesale bag metal plate manufacturers

The most common material is Zinc Alloy (Die-casting) due to its ability to hold intricate 3D details and its weight-to-strength ratio. For high-end luxury brands, Stainless Steel (304 or 316L) is preferred for its superior corrosion resistance and hypoallergenic properties. Ensure the plating process uses Electroplating with an electrophoresis coating to prevent oxidation and color fading. Popular finishes include Shiny Gold, Gunmetal, Rose Gold, and Brushed Nickel.

When ordering custom metal plates, specify the logo technique: Engraving (Laser or CNC), Embossing (Raised), or Debossing (Sunken). For colored logos, Soft Enamel or Hard Enamel filling is standard. Ensure the mold precision is within ±0.05mm to maintain brand integrity. Always request a 3D CAD drawing for approval before the mold-making stage to verify dimensions and attachment hole placements.

Products must be Lead-free and Nickel-free to comply with REACH (EU) and CPSIA (USA) regulations, as these chemicals can cause skin irritation. Additionally, the hardware should pass a 24 to 48-hour Salt Spray Test (ASTM B117) to ensure it won't rust during maritime transport or in humid retail environments. Request SGS or Intertek certification reports from the supplier.

Selection depends on the bag material. Prong-back plates are ideal for leather and thick fabrics, while Screw-back plates offer the highest security for luxury handbags. For lightweight or promotional bags, Hollow rivets or adhesive backing might be used. Ensure the backing plate (washer) is included to prevent the metal from tearing the bag fabric under stress.

The biggest risk is surface scratching and oxidation. Insist on individual polybag packaging or tissue paper wrapping for every single piece to prevent friction during transit. Use Made-in-China.com's Secured Trading services to ensure payment is only released after a Pre-shipment Inspection (PSI) confirms the plating quality and quantity.

Since metal plates involve Mold Costs (Tooling Fees), negotiate for a refund of the mold fee once the cumulative order volume reaches a certain threshold (e.g., 5,000 or 10,000 units). For recurring orders, lock in a raw material price formula based on current Zinc or Copper market rates to avoid sudden price hikes.

Metal plates are heavy but small, making them high-density cargo. For orders under 100kg, Air Express (DHL/FedEx/UPS) is most efficient. Ensure the HS Code (typically 8308.90) is correctly declared to avoid customs delays. For large wholesale volumes, LCL (Less than Container Load) sea freight is more economical, but ensure the outer cartons are double-walled and palletized to handle the weight.
