Zipper Making Machine

Key Components and Processes of Zipper Machines

Zipper Cord Tape Manufacturing

1- Needle Looms: High-speed needle looms are used to weave the zipper tape from yarns like dyeable polyester roto yarn. This tape serves as the foundation for the zipper.

2- Suitable Models: Examples include Jiayi (JY) models like JYZ 10/27, JYZ 12/20, and JYW 14/27, each equipped with grooved rollers for single tape production.

Monofilament Coil Making

·      *  Coiling Machines: These machines create the continuous coil of polyester monofilament, which forms the teeth of the zipper. The coil is stitched onto the zipper tape using specialized needle looms.

Stitching

* High-speed Sewing Machine : The monofilament coil is stitched onto the zipper tape using high-speed sewing machines. Thes machines ensure precise and durable attachment of the zipper teeth.

* Suitable Models : Sting ling models like SSL860 with clutch, SL 860 with servo motor are commonly used for this process.

Dyeing

* Dyeing Machines: After the zipper cord tape is manufactured, it is dyed to the desired color. Dyeing machines come in various capacities, such as 5 kg, 10 kg, 25 kg, 50 kg, and even 500 kg, allowing for flexibility in production volumes.

* Brand: Wenli is a notable brand providing dyeing machines.

Finishing/Pressing
