Ag glass case

When evaluating Ag Glass cases, the primary focus should be on the surface treatment process. Ensure the glass uses chemical etching rather than simple spray coating, as etching provides a more permanent matte finish with a gloss level typically between 35-60 units. Additionally, verify the glass hardness (9H scale) and the presence of an oleophobic coating to ensure fingerprint resistance and smooth touch sensitivity.

You should request SGS or Intertek drop-test reports, specifically looking for MIL-STD-810G compliance. Pay close attention to the TPU/PC frame integration; the bond between the Ag glass backplate and the bumper must be reinforced to prevent delamination. High-quality suppliers on Made-in-China.com often use secondary injection molding to ensure structural integrity.

For the US market, ensure the materials are CPSIA compliant and free from harmful phthalates. For the EU, REACH and RoHS certifications are essential to prove that the chemical etching process and the plastics used do not contain restricted hazardous substances. Always ask for updated lab test reports dated within the last 12 months.

Yes, but you must specify the glass thickness, which should ideally be between 0.5mm to 0.8mm to maintain charging efficiency. If MagSafe is required, ensure the supplier uses N52 neodymium magnets with a magnetic force of at least 800-1100g to prevent accessories from slipping off the matte surface.

The biggest risk is fragility and breakage during transit. You should mandate drop-tested retail packaging and ensure the outer cartons are double-walled (K=K) with corner protectors. For large volumes, specify palletized shipping to minimize manual handling. It is highly recommended to use Made-in-China.com's Secured Trading Service to protect your payment until the goods are inspected.

Ag Glass requires specific tooling. For custom colors or logos, expect an MOQ of 500-1000 units per model. Negotiate for a sample credit, where the sample fee is deducted from the final bulk order. Always clarify the defective rate allowance; in the glass industry, a 1-2% AQL (Acceptable Quality Limit) is standard, and you should negotiate for free replacements in the next shipment for any units exceeding this limit.

Always conduct transactions through verified channels. Before paying, check the supplier's Audit Reports on Made-in-China.com to verify their factory location and production capacity. Use Escrow-based payment terms or Letters of Credit (L/C) for large orders, and never transfer funds to personal bank accounts.

Matte finishes can vary due to acid concentration during etching. To ensure consistency, require the supplier to provide a Golden Sample for your approval and use a gloss meter during the Pre-shipment Inspection (PSI). Specify the Haze value (typically 3%-8%) in the purchase contract to have a measurable standard for quality control.
