Key Engineering Features

We supply ultrasonic horns and ANVIL support components as a set for welding cell tabs to current collectors in li-ion assembly processes (winding & stacking). Our torsional horns for next-generation 46φ tabless batteries — first domestically localized in Korea with 3 patents — are officially supplied to LG Energy Solution's Ochang plant, with US Arizona mass production scheduled for end of 2026.

First domestic localization of torsional horns for 46φ tabless batteries — replacing 100% imported core technology
