30kHz 35kHz Ultrasonic Rotary Sonotrode Core

This precision-built rotary ultrasonic core unit is engineered for continuous textile sealing and radial acoustic welding. It converts high-frequency electrical oscillation into uniform rotary ultrasonic vibration, enabling thread-free bonding and edge cutting on synthetic fabrics without preheating. Optimized for integration into automated sewing and slitting production lines, the unit delivers stable 30kHz or 35kHz resonant output with rated 500W and peak 800W power, supporting long-hour uninterrupted industrial production for nonwoven, polyester and composite textile materials.   Product Description   The core assembly consists of high-performance piezoelectric transducer, precision gear drive structure and customized rotary welding roller. High-frequency ultrasonic waves transfer through the rotary sonotrode to fabric surface, generating instant molecular friction heat to melt and seal fiber materials. The integrated gear set ensures steady rotating speed and even vibration distri…
