In the current production fields of footwear, outdoor equipment, and various textile products, waterproof and sealing performance are of utmost importance. As a key component for product opening and closing, the sealing effect of zippers directly impacts the overall quality.

The traditional zipper gluing process often involves manually applying glue and then hot pressing, which is not only inefficient but also results in uneven glue application, easily leading to poor sealing. In harsh outdoor environments, rainwater is prone to infiltrate the shoes, affecting the user experience. The emergence of Dongguan Qichang's hot air sewing and sealing machine has brought revolutionary changes to the zipper gluing process.


The hot air sealing machine primarily achieves zipper tape attachment through the synergistic action of the hot air nozzle and the roller. The device is equipped with a built-in heating element that can quickly heat the air to an appropriate temperature (typically between 150°C and 300°C, which can be precisely adjusted according to different materials and process requirements). High-temperature hot air is sprayed out from the nozzle, instantly softening the waterproof tape and the material around the zipper. Simultaneously, the roller applies pressure on the tape, ensuring it adheres tightly to the zipper, achieving a seamless seal.

Compared to traditional processes, the hot air stitching and sealing machine possesses significant advantages

High efficiency and speed: The equipment features a high degree of automation, with a gluing speed of several meters per minute or even higher, resulting in a several-fold increase in production efficiency.

Excellent sealing performance: Precisely controlled hot air temperature and roller pressure ensure a perfect fit between the waterproof patch and the zipper, leaving no gaps at the seal, effectively preventing moisture infiltration.

Material saving and environmental protection: The use of TPU hot melt adhesive reduces production costs and minimizes environmental pollution caused by chemical adhesives, aligning with the current concept of green production.

Adapt to various materials: Whether it's the common nylon zippers, plastic steel zippers, or various waterproof patch materials such as TPU, PU, etc., the hot air sewing and sealing machine can achieve a good fit effect, meeting the diverse needs of different products.
