How to check the quality of brand tag

As a professional manufacturer of bag hardware, we provide you with the following quality inspection guidelines for bag logo label hardware to help you identify high quality hardware.How to check the quality of brand tag? How to check the quality of brand tag? Via Material and process standard Alloy formula is made of aviation grade zinc alloy/copper alloy, which has passed the salt spray test for 48 hours without oxidizing (only 24 hours for ordinary alloy). The thickness of gold plating layer reaches 0.5μm (industry standard 0.3μm), and the vacuum ionized gold plating process is adopted, which improves the wear resistance by 30%. Surface treatment process Quality inspection points Physical property test Detailed process control Welding precision laser welding, welding spot diameter ≤ 0.3mm, no air holes under the microscope.Polishing treatment: through six polishing processes, the surface roughness Ra≤0.2μm, to achieve the mirror effect. Environmental protection standard All hardware meets EU REACH environmental protection standard, nickel release ≤ 0.2μg/cm²/week (luxury standard). Salt spray test 96 hours without corrosion in neutral salt spray environment (common hardware only 24-48 hours). How to check the quality of brand tag by Authentication method Brand exclusive process LOGO engraving: CNC precision engraving, font depth 0.15mm, edge slope 45° (fakes are mostly flat printing).Anti-counterfeiting marking: each piece of hardware is embedded with invisible QR code, which can trace the production batch through brand APP scanning.Identification of material propertiesDensity test: the density of genuine copper alloy is 8.5-8.9g/cm³, which can be verified by measuring the ratio of weight to volume with an electronic balance.Magnetic absorption test: stainless steel hardware with a magnet adsorption without reaction, fake goods containing iron components are easily attracted. Production process verification Advantages of cooperation Customization ability support LOGO laser engraving, color PANTONE customization (such as Hermes orange, Chanel black).Provide special texture development…
