Open-End Zipper Pin-Box Introduction

Our open-end zipper pin-box accessories are professionally manufactured for separating open-end zippers and produced in strict accordance with industrial standards. Using high-purity zinc alloy raw materials and precision die-casting with integrated molding, the product features a uniform surface texture, strong structural stability, and a high load-bearing capacity. The pin and box are precisely matched with a secure clamping fit, helping ensure the zipper closes firmly without loosening or slipping during use, while allowing smooth, low-effort separation when the zipper is opened.

After fine electroplating and surface polishing, the pin-box effectively helps resist rust and oxidation, significantly extending the service life of the zipper components. Available in complete standard sizes, the product is designed to match nylon zippers, metal zippers, and plastic zippers of corresponding models. It is widely used in a range of medium- and high-end textile finished products. We also support personalized customization of size, color, and surface finish, and we provide stable mass supply for global merchants and manufacturers—backed by reliable quality and a cost-effective pricing approach.
