How to stitch and fix tpu airbag fabric?

tpu airbag cloth is a special material, with high strength, wear resistance, anti-leakage and other characteristics, is one of the important materials for airbag manufacturing. In the manufacturing process of the airbag, multiple layers of TPU airbag fabric need to be stitched and fixed to ensure the firmness and stability of the airbag. The following will introduce some commonly used TPU airbag fabric suture fixation methods.

1. Hot air welding

Hot air welding is a commonly used method of stitching TPU airbag fabric, in which two layers of TPU material are heated and fused together using a heat gun to form a strong connection. This method is suitable for large balloon and can achieve good suture effect.

2. High-frequency welding

High frequency welding is a fast and efficient suture method suitable for various sizes of airbags. The method uses heat generated by a high-frequency electric field to heat and melt TPU materials together to form a strong connection. The advantage of this method is that the suture can be completed in a short time, and the suture effect is good.

3. Rf welding

Radiofrequency welding is a fast and efficient method for the suture of airbag fabric. The method uses energy generated by a radiofrequency electric field to heat and melt TPU materials together to form a strong connection. This method is suitable for all kinds of airbags, especially for the manufacture of large airbags.

4. Ultrasonic welding

Ultrasonic welding is a commonly used method of stitching TPU airbag fabric. It uses high-frequency vibration to heat and melt two layers of TPU material together to form a strong connection. This method is suitable for all kinds of airbags, especially for the manufacture of small airbags.

5. Hot pressing welding

Hot pressing welding is a common method of stitching TPU airbag fabric. The method takes two layers of TPU material and places them in a hot press, applying high temperature and pressure so that they fuse together to form a strong connection. This method is suitable for thicker airbag materials and smaller airbags.

The above five methods are currently commonly used balloon fabric suture methods, each method has its advantages and disadvantages, it is necessary to choose the appropriate method for suture according to the actual situation. At the same time, when stitching work, also need to pay attention to keep the working area clean and dry, to ensure that the quality and performance of the air bag fabric is not affected.
