What conditions must high-end luggage hardware meet?

With the continuous growth of the luxury goods and high-end travel bag market, consumers' demands for product quality have been constantly rising. Among them, the hardware accessories, as the highlight and core supporting components of the bags, their quality directly determines the product's grade, durability, safety and user experience. As a production factory, we have summarized the core quality requirements for high-end bag hardware as follows:

1.Outstanding material properties:

Stainless steel: Preferentially use high-grade stainless steel such as 304 or 316L.
Zinc alloy: Utilize high-quality die-cast zinc alloys such as Zamak 3, 5.
Aluminum alloy: Employ high-strength aviation aluminum or forged aluminum.
Copper alloy: Require the use of materials with good wear resistance and conductivity. Environmental compliance: Must comply with environmental regulations such as RoHS and REACH, without harmful substances (such as lead, cadmium, mercury, hexavalent chromium, specific phthalates, etc.)

2.Precise Dimension and Tolerance Control:

High Precision: All critical dimensions must be strictly controlled within extremely small tolerance ranges (such as ±0.05mm or more stringent).
Consistency: Ensure high dimensional consistency in mass production.
Compliance with Drawings: 100% production is carried out in accordance with the customer-approved engineering drawings and technical specifications.

3.Top-notch surface treatment effect:

The surface must be smooth, free of scratches, burrs, pits, water marks, bubbles, missed plating, and color differences.
The glossiness and color saturation must be uniform and consistent, meeting the customer's signed sample standards.
The coating should be super hard, super wear-resistant, rich in color, and environmentally friendly, with strong adhesion and high corrosion resistance, meeting the test requirements.

4.Outstanding mechanical performance and functionality.

such as smooth opening and closing without abnormal noise, wear resistance, and tensile strength meeting the requirements.

5.Strict Packaging and Protection

The packaging method must be resistant to scratches and impacts, prevent oxidation and moisture, have clear labels, and be easy to trace
