As a common sewing method, zipper expander machine is widely used in high-end products such as clothing, luggage, and car seats. By processing the zipper through the heating elements，and then stitching the fabric,makes fabric wrinkling free, the product can be more beautiful and durable. Zipper pre-expansion machines can improve production efficiency and reduce manual operations. They are suitable for pre-expansion of various zipper materials and types, such as nylon zipper, resin zipper, nylon / resin mixed zipper, etc. This wide applicability enables companies to flexibly choose zipper materials suitable for their products to meet diverse production needs. Therefore, the application value of zipper pre-expansion machines cannot be ignored. It can not only improve product quality and production efficiency for various industries, but also is an important means to promote industrial progress.

When using the traditional manual method to preheat the zipper belt, we often face the problem of unstable steam pressure, which makes it difficult to meet the expected standard requirements.But now, we can use advanced equipment to carry out the zipper extensions. The application of heating elements can not only avoid the problem of zipper closure, but also adjust the coefficient according to the pre-shrinkage rate of each batch of cloth, so as to achieve the uniformity of the pull-out ratio and the consistency of texture,make the garments anti-wrinkle.

Compared with the traditional air spray mode, the use of zipper pre-expansion machine can save time, be easy and easy to use. The traditional mode requires workers must standing and moving all the time, while the use of zipper pre-expansion machine can easily achieve efficient production while sitting, which makes the work more comfortable and convenient.

Therefore, it has become a trend to use high-tech equipment to process zipper pre-shrinkage, which can not only improve production efficiency, but also ensure stable quality, making us more confident and assured in the production process.

【main functions】
1. Heating: The zipper is preheat by the heating elements to soften its plastic material and create conditions for zipper pre-expansion.
2. Pre-expansion: Expand the zipper horizontally and maintain a specific expansion ratio in its length and width. This ensures that the zipper can be inserted into the fabric well and is more comfortable when worn.
3. Cooling: The zipper needs to be cooled after pre-expansion to maintain its shape and size.
4. Separation of the rack: After pre-expansion, the rack of the zipper is separated to improve the insertion performance of the zipper fabric while providing a certain degree of aesthetics.

We provide a zipper pre-expansion machine: KL-2471A Zipper Pre-expansion Machine, to help the factory manufacturers to solve the long-term problem of the zipper of the placket is arch.

KL-2471A Zipper Pre-expansion Machine

By pre-expanding the zipper belt, the placket will not arch and the zipper will not twist in the subsequent process, making the clothes look higher quality. The difference in the speed ratio of the differential wheel inside the machine makes the expansion ratio of the zipper belt very stable. Compared with the traditional method, the expansion ratio of pulling out the zipper is more stable, and the quality will not be affected by the worker's proficiency or force, and the efficiency is higher.

In general, the main function of the zipper pre-expansion machine is to provide a treatment that can optimize the relationship between the zipper and the fabric, further ensuring the quality and comfort of the garment. Solve the problem of zipper arching in daily sun protection clothing, down jackets, and jackets. The zipper is flat after pre-expansion, which is suitable for all kinds of clothing zippers, so that the zipper will no longer arch during the sewing process.
