1. In modern manufacturing, welding technology is one of the key means to achieve material connection. With the continuous progress of technology, various advanced welding techniques have emerged, and ultrasonic welding is one of the highly regarded ones. Relying on its unique advantages, this technology has been widely applied in many fields, especially in the manufacturing of plastic products. As a common daily necessity, the connection quality of the handle of a kettle directly affects the product's performance and safety. Ultrasonic welding technology plays an important role in the welding process of the kettle handle, bringing new development opportunities to the kettle manufacturing industry.

2. During the use of a kettle, the handle needs to withstand a certain amount of tensile and torsional forces. If the handle is not welded firmly, it is likely to fall off during use, posing a safety hazard to users. Ultrasonic welding can form a strong connection between the kettle handle and the kettle body. The welding strength formed can be comparable to that of the raw material itself. Tests have shown that the pull-off force of a kettle handle welded by ultrasonic welding can reach dozens of kilograms or even higher, far exceeding the requirements of industry standards, ensuring the safety and stability of the kettle during long-term use.
