Sungwoo

What Sungwoo does

Sungwoo Electronics (성우전자) is a South Korean ultra-precision component manufacturer headquartered in the Sihwa Industrial Complex in Ansan, Gyeonggi-do. The company operates four business segments: Mobile Communications (producing Shield Can internal EMI-shielding parts plus exterior Deco, Key, and Metal Case components for handsets), Imaging and Optical Devices (영상/광학기기) which includes Mechanical Shutter for Mobile, Molds (금형), and Smart Cards (스마트카드). Its core technology is ultra-precision manufacturing (초정밀 기술) — precision metal forming, decoration/key processing, in-house mold design and production, and optical assembly — applied across multiple product lines, with in-house tooling claimed to enable tighter tolerances and reduce third-party dependency.

The company is in its 38th–39th fiscal year of operations (consistent with a 1987 founding), is led by co-Representative Directors Jo Il-hyeon (조일현) and Kim Young-do (김영도), and operates as a B2B component supplier via direct enterprise sales to global handset OEMs and electronics manufacturers. Public-facing channels are limited to a multilingual corporate website (Korean/English/Chinese) and a Cyber PR notice board used for material disclosures such as fiscal year closing announcements. The company self-positions as a future-leading ultra-precision component specialist with a global production network, but no specific customer logos, overseas facility locations, distributor roster, parent company, or cap table were disclosed in the available material.
