WHAT IS ULTRASONIC TECHNOLOGY?
Ultrasound is the name given for sound waves that have a frequency that is higher than the upper limits of human hearing. It is no different from the normal sound waves that we can hear as noise in day to day life. The only difference is that we as humans cannot hear them.

HOW DOES ULTRASONIC SEWING MACHINES COMPARE TO STANDARD SEWING MACHINES?
While the traditional needle and thread sewing machines are and always will be a common site in clothing factories around the world, ultrasonic welding is proving to be a superior alternative in so many clothing sectors including sportswear and outdoor clothing. On traditional sewing machines, the needle punctures holes into the fabric, weakening its structure while the overlap of fabrics at the joint creates thick seams that are bulky, can restrict movement, are wasteful and adds weight to the garment. A multitude of negatives in the sportswear market. With our ultrasonic sewing machines, we can create a weld so small that it has to be backed with a seam sealing tape. Our standard weld created from an ultrasonic sewing machine is just 0.5mm!
WHAT CAN ULTRASONIC SEWING MACHINES AND CUTTING MACHINES BE USED FOR?
Hemming
Ribbons & trims
Cutting fabric templates
Zip slots
Joining fabrics together with and without seam allowance.
WHAT FABRICS AND TEXTILES CAN BE USED WITH ULTRASONIC MACHINES?
There are a few requirements that have to be met for fabrics and textiles that are to be used in ultrasonic welding. A broad melting range with a high coefficient of friction are required while the fabric must have a consistent thickness throughout. In order to achieve the melting point that allows for ultrasonic bonding, the textile must have a 20% minimum thermoplastic content with sufficient strength within the material to withstand the welding process. As an example, polyester is a common and popular choice of fabric material used for ultrasonic welding and sewing.
