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 ultrasonic mechanical vibration can focus on ultrasonic welding head, by ultrasonic welding head sends the ultrasonic energy to the welding area, due to the welding area is two welding interface of the acoustic resistance is big, so can produce local high temperature, the two fabric contact rapidly melting, coupled with a certain pressure, the synthetic one. When the ultrasound stops, the pressure is allowed for a few seconds to solidify and form a strong molecular chain that can be welded to a Velcro that is close to the strength of the raw material.

Compared with the traditional sewing or glue Velcro connection in the past, ultrasonic welding bonding strength, long-term use will not appear out of the phenomenon.

Velcro is not confined to the development of the clothing, shoes and hats, and other areas of the fabric, in recent years, the application of Velcro favored by electronic technology industry closely related to science and technology products, after another Velcro related products are research and development design, and put into use in mass production, dell, samsung, apple, lenovo and so on a large number of high-tech electronic product using Velcro cable tie, All kinds of products with different design forms can be seen everywhere in electronic life. With the development of the Velcro in the field of high technology, the traditional production technology of the Velcro 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 the use of ultrasonic technology for welding, the production of teeth of the ultrasonic mold Velcro binding belt welding firm, stable and firm welding effect. Velcro is generally made of nylon, blend and polyester, and ultrasonic welding and processing of these materials is the best.

The mold making of ultrasonic welding of Velcro tie belt is very important. Some teeth can be produced. The welding marks of teeth are the marks of Velcro tie belt. Adjust welding time, fixed line time, delay time.
