Textile Ultrasonic Welding Machine/Ultrasonic Welding Machine For Fabric points of attention:

In the ultrasonic welding of non-woven fabrics, the welding time has an important impact on the welding quality: the welding time is insufficient, the material contact surface cannot reach a complete melting state, the material cannot be fused; the welding time is too long, the solder joint is black, the welding situation occurs, and the solder joint and the non-solder joint junction line are cut off. This phenomenon seriously affects the overall solder joint strength, and it is also unacceptable to the appearance of the product.
The influence of welding pressure on the quality of the welding joint is more complex, and the experiment found that the welding pressure has a greater impact on the thickness size of the melting area and the density of the material after welding in the melting area: when the welding pressure is small, the material after the thermoplastic in the melting area is fluffy, there is obvious fibrousity, and the strength of the solder joint is low; when the welding pressure is too large, the thickness of the melting area is very small, the solder joint is overburned, there is a phenomenon of burning through, and there is no connection strength of this solder joint
In practical applications, welding time is more important, it directly affects the time of the entire welding process, which in turn affects the production capacity of the entire equipment, and the welding pressure is an adjustable amount. Nonwovens of different materials and thicknesses can change the quality and effect of the solder joint by changing the welding pressure.
Advantages of ultrasonic welding nonwovens
Superior speed and productivity
Ultrasonic welding technology cuts, stitches and bonds nonwovens at an extraordinary speed. In a continuous production line, ultrasonic can weld nonwoven layers in less than a second, resulting in a repeatable bond as strong as the base metal.
Strong, continuous seams and ties
The main advantage of ultrasonic technology compared to sewing is that there is no need for stitching, and there is no need to form mechanical holes in the fabric that can accommodate and hide microorganisms or contaminants, resulting in high-strength, high-integrity joints and adhesives.
Zero consumables or contaminants
In contrast to adhesives, ultrasonic technology eliminates the additional cost of consumables, the extra amount of work applied, the additional time required for installation and drying, and the risk of exposure to chemical contaminants. Ultrasonic seams can be used as soon as they are produced.
High energy efficiency
Ultrasonic technology only consumes power when used to cut or bond materials. In addition, since the process immediately generates the required frictional heat by ultrasonic vibration, there is no additional energy consumption or waste associated with preheating and keeping the hot knife or thermal bonding tool at the desired operating temperature.
