KGA

KGA makes the specialized machines used in the first stage of rechargeable battery production, equipment that coats, presses, and slits the electrode materials that go inside a battery cell.

Listed on KOSDAQ, Korea's tech and small-cap board, it supplies these electrode-process machines to battery cell makers and electric-vehicle manufacturers in South Korea, Europe, and the United States. Alongside its core battery-equipment line, the company also develops and supplies automated duct-fabrication machines and installs industrial ventilation duct systems, which form a separate, steady revenue stream.
