What Dong-A Hwaseong does

Dong-A Hwaseong (legal entity: 주식회사 DACM, DBA SY동아) is a South Korea-based industrial rubber components manufacturer founded in 1974, publicly listed on the Korea Exchange under code KR7041930009 and headquartered in Gimhae, Gyeongnam Province. The company produces and supplies eco-friendly industrial rubber parts across three product categories: Automotive (자동차) for vehicle applications, Home Appliances (가전) for appliance manufacturing, and Fuel Cells (연료전지) for fuel cell technology applications. Its core technology is industrial rubber compounding and molding, with downstream plating capability evidenced by an active plating factory in Hwaseong, Gyeonggi Province, and it operates multiple production sites including the Gimhae headquarters, a Cheonan factory, and a US subsidiary, indicating a multi-site manufacturing footprint.

The company operates a B2B direct-sales model targeting Korean automotive manufacturers, home appliance makers, and fuel cell industry customers under a single-country/domestic distribution posture, with overseas exposure limited to the US subsidiary. Pricing is not publicly disclosed. The customer base is not enumerated in available sources, though the segment structure (three discrete use-case categories) implies a relatively concentrated set of OEM relationships typical of Tier-2 automotive component suppliers. Governance is led by Representative Director and Chairman Jeon Chang-ok, inaugurated December 17, 2025, with the 2025 Business Report published March 20, 2026. The firm employs 251-500 staff and reported 2025 revenue on the order of KRW 280B (approximately US$200M at prevailing exchange rates), with operating income around KRW 12B and a one-off-boosted net income near KRW 19B, reflecting a mature, low-growth industrial profile with margin pressure and meaningful valuation derating since 2023.
