Wholesale pure titanium frame

Pure titanium contains at least 99% titanium, offering the highest biocompatibility and corrosion resistance. Beta Titanium is an alloy (often with vanadium and aluminum) that provides greater flexibility and memory properties, making it ideal for thin temples. Always check for the 'Titanium' or 'Ti-P' stamp on the bridge or temples. For bulk orders, request a Material Test Report (MTR) to verify the grade (typically Grade 1 to Grade 4 for pure titanium) to ensure you are not paying pure titanium prices for cheaper alloys.

Focus on Vacuum Plating (IP - Ion Plating) technology, which ensures the color does not peel and is hypoallergenic. Check the hinge durability; high-end frames should withstand 30,000+ opening/closing cycles. Additionally, verify the weight-to-strength ratio—a standard pure titanium frame should weigh between 10g to 15g (without lenses). Ensure the nose pads are made of medical-grade silicone or titanium to complement the frame's anti-allergic properties.

For the US market, frames must be registered with the FDA as Class I medical devices and comply with ANSI Z80.3. For the EU market, CE Marking is mandatory, and the product must meet ISO 12870 standards, which include tests for nickel release (EN 16128) to ensure they are safe for sensitive skin. Ensure your supplier on Made-in-China.com can provide these specific test reports before finalizing the contract.

Titanium requires specialized welding in an argon-shielded environment and high-pressure stamping, which increases production costs compared to Monel or Acetate. To optimize costs, look for suppliers who utilize CNC precision cutting to reduce material waste. MOQs (Minimum Order Quantities) for custom titanium designs usually range from 300 to 500 pairs per model; however, sourcing Ready-to-Ship (RTS) designs from established manufacturers can lower your initial investment risk.

The primary risk is material substitution, where suppliers use 'titanium-plated' steel instead of solid titanium. To mitigate this, use Third-Party Inspection services (like SGS or Intertek) to perform a density test or salt spray test before shipment. Another risk is intellectual property infringement; ensure the designs do not violate existing brand patents in your target country.

Focus on Tiered Pricing—ask for price breaks at 500, 1,000, and 5,000 units. Negotiate for OEM branding (laser engraving your logo) to be included in the unit price. Request a 2%-3% spare parts allowance (screws, nose pads, extra temples) to handle minor after-sales issues without needing international returns.

Always utilize Secured Payment services provided by the platform to ensure funds are only released upon proof of shipment. Use Letter of Credit (L/C) for very large volumes or Telegraphic Transfer (T/T) with a 30% deposit and 70% balance against the Bill of Lading (B/L). Never wire money to personal bank accounts; ensure the account name matches the registered business name on the supplier's profile.

Eyewear is high-value but low-volume. Air Freight or Express Couriers (DHL/FedEx/UPS) are recommended for batches under 100kg to ensure fast turnover and reduced risk of crushing. Ensure the supplier uses individual polybags and rigid inner boxes with double-walled outer cartons. For larger sea freight orders, insist on palletization and moisture-proof wrapping to prevent corrosion of metal components during long transit times.
