At the 2026 electronica Munich trade fair, JiaoCheng Ultrasonic and TE Connectivity signed a strategic cooperation agreement to jointly advance the mass production and implementation of "full aluminum-for-copper substitution" technology in the automotive sector. The collaboration focuses on addressing critical challenges in scaling this technology and fostering the development of an associated innovation ecosystem. This partnership aims to expand the application of ultrasonic welding technology in automotive wiring harness manufacturing and accelerate the transition of aluminum-for-copper substitution from single-point validation to full-scale, industry-wide deployment.
