Ultrasonic plastic welding machine is a kind of equipment that uses ultrasonic technology to fuse thermoplastics into a whole to obtain the required products.

This device can be widely used in the automotive industry, packaging industry, toy industry, electronic and electrical industry, etc.

Principle of ultrasonic plastic welding machine:

1. Firstly, the ultrasonic energy is transmitted to the plastic surface to be welded through the upper mold (or concave mold). Due to the friction between the surface and internal molecules, high temperatures are generated, causing the contact surface of the two plastics to quickly melt and then fill in the overlapping position. When the vibration stops, the two materials are tightly connected together, achieving the purpose of welding, while generating huge heat to firmly fix the two products.
2. When the pressure is applied, continue to apply pressure, so that when the surface is compressed, a certain internal stress will continue to be generated. When the yield point of the material is reached, its chemical bond will break, so as to achieve the purpose of welding.
3. By utilizing the characteristics of ultrasonic waves that instantly vibrate onto plastic products, it creates a warm feeling similar to being massaged by hand, and has a certain tensile force until the product dissolves. After processing, it can achieve water tightness and air tightness, and food placed in the mouth will not melt. Generally, it can be formed in one go to meet the user’s needs.
4. Using high-frequency waves to transmit to the metal body, countless small bubbles smaller than pinholes are generated inside the metal body, and then a large current is applied to force them to grow rapidly and collide with each other, achieving the goal of welding.
