Ultrasonic Velcro Welding

Velcro is commonly used as a clothing attachment materials, both sides of the molecular mother. It is a fine, soft fiber and on the other side is the harder hooked bristles. In addition to clothing, widely used in various fields, life can be seen everywhere.

With the changes of the times and the progress of science and technology, the traditional Velcro production technology has been unable to meet the requirements of people for its beauty and long-term use performance. Traditional Velcro mainly rely on the production of two ways: one is the needle sewing, needlework sewing cloth with no binding between, but by a thin line to tie them together after long-term use of the connecting wire is easy to break, resulting in Velcro failure, and the sewing interface is clearly visible, poor aesthetics; the second is the adhesive connection, this way Velcro aesthetics than sewing needle high, but there will be degumming after long-term use, Lead to Velcro failure.

CHEERSONIC understanding of the customer's needs, we recommend using CHEERSONIC ultrasonic independent research and development of ultrasonic welding equipment.

Needless sewing equipment, no glue, without any auxiliary material can be Velcro elastic ribbon or ribbon welding together. Ultrasonic welding equipment is the mechanical vibration of ultrasonic energy can be focused on the ultrasonic horn, the ultrasonic horn through the ultrasonic energy transmitted to the weld zone, as the two welding at the interface acoustic resistance, it will have a local high temperature, resulting in two fabrics The contact surface melts quickly, plus a certain pressure, make it integrated into one. When the ultrasonic stop function, let the pressure continued for a few seconds, so that its solidification molding, thus forming a solid molecular chain, to achieve the purpose of welding Velcro, welding strength close to Velcro raw material strength.
