Import 5# Metal Zipper Open-End — Buy in Bulk from Supplier in China

The 5# metal zipper open-end from Shenzhen Do-Well Industry And Trade ) Co., Ltd is a finished separating zipper with brass teeth and an auto-lock slider mechanism, supplied in 50 cm standard lengths with custom sizing available. The open-end construction features a pin-and-box bottom stop that allows the two zipper halves to fully separate, a format essential for jackets, coats, and other front-opening garments. The supplier specifies brass construction for corrosion resistance and an auto-lock feature to prevent involuntary opening under stress.

Brass zipper teeth in the 5# gauge typically contain a copper-zinc alloy with 58-68% copper content, offering good machinability and colour stability compared to aluminium alternatives. The auto-lock slider contains a small internal cam that engages the teeth when the pull tab is released, a mechanism tested to cycles of 5,000-10,000 openings in standard quality grades. Open-end zippers require precise alignment of the pin and retaining box, with typical insertion force below 25 N and separation resistance above 80 N for reliable garment performance. The 50 cm length cited suits standard adult jackets; deviations from this require confirmation of pin-box geometry compatibility.

This product serves apparel manufacturers, uniform suppliers, and outerwear brands who need ready-to-sew finished zippers rather than cut-from-roll components. The auto-lock function is particularly valued in active and children's wear where security of closure matters. Buyers should confirm with Shenzhen Do-Well Industry And Trade ) Co., Ltd whether the stated 50 pieces per pack configuration applies across all colours and lengths, and whether custom lengths incur tooling charges or extended lead times.
