An ultrasonic welding horn, also known as an ultrasonic welding sonotrode, is a specialized tool used in ultrasonic welding processes. It is designed to transmit high-frequency vibrations to join two or more materials together. The horn is typically made from a durable metal alloy, such as titanium or aluminum, and is shaped to concentrate the ultrasonic energy at the welding interface. When the horn is activated, the high-frequency vibrations create friction and heat at the joint, causing the materials to melt and fuse together. The ultrasonic welding horn plays a critical role in ensuring efficient and reliable bonding in various industries, including automotive, electronics, packaging, and medical devices.
