Ultrasonic Metal Welding Machine

Ultrasonic metal welding machines bond copper and aluminum conductors — wires, cables, terminals, and battery tabs — through high-frequency mechanical vibration that scrubs away oxide layers at the contact interface and generates solid-state metallurgical joints without melting the base material. This process produces stronger, lower-resistance connections than crimping or soldering, with no flux, no heat-affected zone, and no consumables, making it the preferred joining method for automotive wiring harnesses, EV battery pack assembly, and industrial cable termination. Ming Jilee's ULTRA-MWH-6200 is a 6,200 W half-wavelength ultrasonic metal welding machine with maximum welding force of 6,000 N and cross-section capacity of 50 mm² copper or 70 mm² aluminum — suited to medium and large conductor welding in automotive wiring systems and EV applications. The machine operates on a 100 mm cylinder stroke with air cooling and a 12-inch touch panel for full parameter management. The category also includes the ULTRA-MWH-9000/12000 full-wavelength models for heavier conductor cross-sections, and the ULTRA-MWH Wire-to-Terminal series with automatic terminal feeding for high-volume harness assembly lines. CE certified, ISO-9002.
