Dongguan Eontec Co., Ltd.: history, ownership, mission, how it works & makes money

Founded in May 1993 and listed on the Shenzhen Stock Exchange in 2012 under ticker 300328.SZ, Dongguan Eontec Co., Ltd. has grown into a vertically integrated light-alloy manufacturer with about 2,583 employees and a registered capital of 690 million yuan; yet its 2024 revenue of 1.65 billion yuan reflected a 3.19% decline from 2023 as the company balances R&D-led ambitions-embodied by its mission to 'Cast a better life' and in-house alloy labs-with commercial realities, while founder and general manager Weirong Li remains the largest shareholder and, as of December 12, 2025, the stock traded at 16.03 yuan per share with a market capitalization of 11.07 billion yuan and recent government support highlighted by a July 2025 subsidy of 1.1462 million yuan (equal to 113.99% of the most recent audited net income attributable to shareholders) as it supplies amorphous, magnesium and aluminum alloy components and value-added services across consumer electronics, medical, communications and automotive sectors.
