DSE Inc. is a specialist manufacturer of industrial plastic enclosures, founded in Busan, South Korea in 1990. Our brand HIBOX protects electronics for 100+ customers in 20+ countries. In 1998, DSE became the first plastic enclosure maker in Korea to earn UL certification (UL508A Type 4X), and today also meets TÜV IP67/IK08, CE, and VDE standards. Built with 3.4 mm walls — 30% thicker than the UL minimum — 100% virgin resin, and German-engineered UL-listed foamed gaskets, every enclosure is made fully in-house at our Busan factory. The lineup spans 9 series and 200+ standard sizes from 50 mm to 1 m in ABS, PC/ABS, and PBT/PC, with custom machining and printing available. Part of the KOSDAQ-listed ATON Group since 2023, DSE grows with partners in automation, telecom, and renewable energy.
