Traditional Velcro production mainly relies on two methods, one is needle-and-thread sewing, sewing cloth between the cloth does not combine, just rely on a thin thread to bind them together, long-term use, the connecting line is easy to fracture, leading to the failure of the Velcro, and the sewing interface is clearly visible and poor appearance: the second is the adhesive connection, which this method has a higher aesthetic than needle-thread sewing, but there is also a phenomenon of degluing after long-term use, resulting in the failure of Velcro.Ultrasonic preparation without needlework without glue without any auxiliary materials can be a variety of cloth Velcro elastic belt woven belt welding together. Ultrasonic welding equipment is to be ultrasonic

The mechanical vibration energy of the wave is focused on the ultrasonic welding head, and the ultrasonic energy is transmitted to the welding area through the ultrasonic welding head. Due to the high acoustic resistance of the welding area, that is, the interface of the two welding surfaces,because this can produce local high temperature, cause the contact surface of two cloth to melt rapidly, after adding certain pressure, make its synthesize an organic whole. When the ultrasound stops working, let the pressure the force lasts for a few seconds, causing it to solidify into a solid chain of molecules that will weld the Velcro close to the original material the material strength.Compared with the two traditional ways of connecting the Velcro in the past, the bonding strength of ultrasonic welding is large, and the phenomenon of detachment will not occur after long-term use.

Velcro is not limited to the development of clothing, shoes and hats and other fabric fields. In recent years, the application of Velcro is optimistic about the electronic high-tech industry and closely related to scientific and technological products.One after another, Velcro related products have been developed and designed, and a large number of production put into use, Dell, Samsung, Apple, Lenovo and a large number of high-tech electronic products. Products are using Velcro tape, various design forms of products in the electronic life everywhere. With the development of Velcro in the high-tech field, the traditional magic the production technology of surgical patch has been unable to meet the needs of its aesthetic and long-term performance.Velcro ultrasonic welding machine is also known as nylon adhesive belt welding Velcro welding machine, Velcro ultrasonic welding machine is welding with ultrasonic technology, the production of teeth the ultrasonic mold will weld the Velcro tie belt firmly, and the welding effect is stable and firm. Velcro is generally made of nylon, polyester, and ultrasonic welding and processing these materials work best.
