Introduction to the advantages of Velcro ultrasonic welding machine

With the changes of the times, Velcro is not only limited to the development of clothing, shoes and hats and other fabrics. In recent years, the application of Velcro has been favored by the electronic high-tech industry and is closely related to technological products. Velcro related products have been developed one after another. Designed and mass-produced and put into use, a large number of high-tech electronic products such as Dell, Samsung, Apple, and Lenovo have used Velcro straps, and various products with different designs can be seen everywhere in electronic life. With the development of Velcro in the high-tech field, traditional Velcro production technology can no longer meet people’s needs for its beauty and long-term performance.

Traditional Velcro production mainly relies on two methods. One is needlework. There is no bond between the cloth and cloth sewn with needlework, but a thin thread is used to tie them together. After long-term use, the connecting line is easy to break. Causes the magic tape to fail, and the stitched interface is clearly visible and has poor aesthetics: the second is the adhesive connection. This method has a higher aesthetics than needlework, but it also has degumming after long-term use, which causes the magic tape to fail. .

Ultrasonic equipment does not require needles and threads, does not require glue, does not require any auxiliary materials, and can weld all kinds of fabrics, such as velcro, elastic band, and webbing. Ultrasonic welding equipment focuses the mechanical vibration energy of the ultrasonic on the ultrasonic welding head, and transmits the ultrasonic energy to the welding area through the ultrasonic welding head. Because the welding area is the large acoustic resistance at the interface of the two welding, it will generate local high temperature, resulting in The contact surface of the two cloths melts quickly, and after a certain pressure is applied, they become one. After the ultrasonic stops, let the pressure continue for a few seconds to make it solidify and shape, thus forming a solid molecular chain to achieve the purpose of welding Velcro, the welding strength can be close to the strength of the Velcro material.

Compared with the two traditional ways of connecting with Velcro to insert wings, ultrasonic welding has high bonding strength, and it will not be detached after long-term use.
