Invisible Zipper Welded Bottom Stop Machine

Designed for precision and efficiency, our Invisible Zipper Welded Bottom Stop Machine utilizes high-frequency vibration from an ultrasonic horn to seamlessly melt and reform zipper teeth into a durable bottom stop. By directly applying ultrasonic energy to the teeth, the process eliminates the need for additional consumables-such as wire or separate stop parts-significantly lowering operational costs and simplifying material management.

At the core of its automation is an integrated sensor-based hook needle system. This intelligent feature automatically detects the zipper's gapping space, ensuring accurate positioning of each bottom stop without manual measurement or length input. The result is consistent placement, reduced setup time, and enhanced production flow-ideal for continuous, high-volume manufacturing environments.

The machine produces bottom stops that excel in both aesthetics and performance. Each stop is molded to a smooth, uniform shape with high structural integrity, free from burrs or rough edges. The ultrasonically fused finish provides superior resistance to washing, abrasion, and daily wear, extending the lifespan and reliability of the final zipper product.

Engineered for modern factories seeking to improve quality and reduce costs, this system combines advanced ultrasonic technology with smart automation to deliver a cleaner, stronger, and more cost-effective solution for bottom stop application. It is an ideal upgrade for zipper manufacturers focused on precision, durability, and streamlined production.
