Brass Alloy Teeth
The zipper uses brass alloy teeth with a firm metal construction suited to regular opening and closing.
The teeth are evenly arranged along the tape to maintain consistent engagement with the slider. The metal construction provides the strength needed for denim and other garments where the zipper is subject to repeated use.
For bulk production, tooth alignment, tooth spacing and surface appearance can be checked against the approved sample and product specification.
Spring Auto-Lock Slider
The zipper is fitted with a spring auto-lock slider and matching pull tab.
The spring mechanism helps hold the slider in position after pulling, reducing unintended movement during normal wear. The slider is designed to engage smoothly with the metal teeth without excessive resistance.
The pull tab also provides a practical grip for opening and closing the zipper, making it suitable for frequently used garment openings.
Woven Fabric Tape
The brass alloy teeth are attached to a woven fabric zipper tape. The tape provides the flexibility needed for sewing onto denim, trousers and other garment fabrics.
Multiple solid tape colors are available, including neutral and fashion shades shown in the product range. Custom colors can also be discussed according to the garment fabric and production requirements.
Quality Control
For bulk orders, the zipper can be checked according to the approved specification, including size, tooth alignment, tooth spacing, surface finish, tape width, slider movement, auto-lock function, pull tab structure, zipper length and overall appearance.
An approved sample can be used as the reference for bulk production to help maintain consistency in dimensions, color, metal finish and zipper function.
Before shipment, finished zippers can also be inspected for visible defects such as damaged teeth, uneven alignment, abnormal slider movement and tape defects.
Applications
This Size 4 brass alloy zipper is suitable for jean fly plackets, trousers, casual garments, fashion outerwear and small leather pouches.
The metal teeth provide a more substantial appearance and construction for garments where a stronger zipper is preferred.
