Sewing machine that does not require needle thread …

Ultrasonic welding is a sewing machine without needle thread. It mainly uses ultrasonic energy to weld with the fabric and quickly merge into one. Sewing various fabrics with high efficiency and precision, such as protective clothing, masks, packaging bags, etc. The equipment has technical advantages such as cleanliness, safety, and stable performance. The most important thing is that the products sewed with the ultrasonic sewing machine have no pinholes and no bacteria and viruses. They are especially suitable for protective clothing.

Ultrasonic welding technology mainly transmits the ultrasonic energy to the welding area through the upper welding parts. Due to the poor thermal conductivity of plastics, nylon, chemical fiber, non-woven fabrics, multi-layer cloth, gold cloth and other materials, the acoustic resistance at the interface between the two welds is large. When the local high temperature is generated, the heat cannot be dissipated in time, and it is gathered in the welding area. The two contact surfaces melt quickly, and the pressure makes it merge into one.
