Business overview
Source: DART corporate disclosureFounded in 1983 and listed on KOSDAQ in 1997, WonIk operates four business segments spanning pressure sensors and healthcare. Its Hybrid IC segment, which accounts for over 90% of revenue, produces low-pressure sensors, while its Healthcare segment sells the dermo-cosmetic brands Cell Fusion C and Suiskin and distributes medical devices including the Lumenis Holmium Laser, KOELIS TRINITY 3D PROSTATE SUITE, and KARL STORZ laparoscopic surgical instruments. It operates an MEMS-based pressure sensor R&D lab that has completed development of items such as metal heaters for semiconductor equipment and high-pressure ceramic sensors, and plans to develop low-pressure sensors and massage-device sensors by 2026.
