Product Description

Product Overview

Redefine belt customization with our 20mm Adjustable Fashion Pin Buckle for Bag Belts, a seamless fusion of zinc alloy durability and ergonomic precision engineered for modern accessory needs. Crafted through a high-pressure die-casting process, this buckle maintains structural integrity while achieving a sleek profile ideal for 18–22mm wide belts. Its standout feature is the spring-loaded pin mechanism—calibrated with a 0.5mm tolerance—that enables instant length adjustments without tools, perfect for on-the-go users. The triple-layer electroplating system (copper underlayer for adhesion, nickel barrier for corrosion resistance, and 24K gold topcoat for luster) delivers 500+ hours of salt spray resistance (per ASTM B117 standards), ensuring longevity in humid or coastal environments. With a textured grip surface (0.3mm raised patterns) to prevent slippage, this buckle supports laser-engraved logos (up to 3 colors) and offers 12+ finish options, striking the perfect balance between industrial strength (80kg tensile load) and sleek aesthetics for fashion-forward designs.

FAQ

Q: Can this buckle be used with synthetic leather?

A: Yes. The non-abrasive POM slider (food-grade, FDA-compliant) features rounded edges that prevent tearing or marking on polyurethane (PU), PVC, or vegan leather surfaces.

Q: What’s the minimum order quantity for custom colors?

A: MOQ is 500 units for standard finishes (7-day lead time); 1,000 units for custom PMS color matching, which includes a digital proof and physical sample approval (10-day lead time).

Q: Does the metal frame rust?

A: No. The zinc alloy core is protected by a nickel barrier layer (3μm thickness) and topcoat, forming a corrosion-resistant barrier that withstands saltwater, sweat, and moisture exposure.
