How Does The Ultrasonic Welding Machine Weld Plastic?

The principle of ultrasonic welding, as its name implies, means that when the high-frequency vibration generated by ultrasonic is applied to the contact surface of two thermoplastics, local high temperature is generated through high-speed friction, which makes the contact surface of two plastics melt rapidly. After a certain pressure is applied, it is fused into one.
Ultrasonic welding machines commonly include handheld welding machines and desktop welding machines, of which handheld welding machines are often used for the processing of hot melt plastic products such as single point welding, screw embedding, riveting, spot welding, embossing, etc., while desktop ultrasonic welding machines are medium and large equipment, often used in the welding of hot melt plastic products in medical equipment, 3C electronics, auto parts, printing consumables, household appliances, household goods and other industries.
