What Woojin Plaimm does
Woojin Plaimm Co., Ltd. is a South Korea-based manufacturer of plastic injection molding machines (IMMs), founded in 1985 as Woojin Machinery and listed on the KOSDAQ in 2001 and the main board of the Korea Securities and Futures Exchange in 2006. The company designs and builds a broad product portfolio spanning clamping forces from 50 to 4,300 tons across five series: A5 premium line (DL-A5, TH-A5, TE-A5), G5 modern line (DL-G5, TB-G5, TE-G5), VH vertical line (VHA-RS, VHL-RS, VH-RG5), Multi dual-color line (NC-G5, TE-NC), and special-purpose machines for PET preforms and pallets. Differentiated technologies include Super-Foam, the world's first low-pressure physical microcellular foaming IMM (2018), Clean-Foam eco-friendly foaming (2025), tie-bar-less architectures, and proprietary IMC 500/700 controllers, several of which have won Red Dot Design Awards in 2023-2024.
The company targets manufacturers in automotive (interior, exterior, under-hood components), housewares and consumer goods, home appliances, and cosmetics/packaging verticals through direct enterprise field sales. Domestically Woojin operates 8 regional sales headquarters, 3 centers, and 5 branches across Korea; internationally it runs 4 wholly-owned subsidiaries (USA/Buffalo Grove, China/Ningbo, Mexico/Monterrey, Austria/Leobersdorf R&D), 17 branches, and 12 agents across 42 countries. The business model is predominantly capital-equipment hardware sales supplemented by aftermarket service revenue through the Speed Club program and mobile application, which provides technical consultation, on-site diagnosis, repair, and real-time service tracking.
Financially, Woojin has experienced a material revenue and profitability contraction since 2022. Revenue declined from approximately $144M USD (2022) to ~$105M (2025) on a converted basis, a 27% drop, while net income collapsed from roughly $13.5M (2021) to ~$1.1M (2025). Operating margin compressed from ~9% in 2022 to ~1.4% in 2025, indicating either significant fixed-cost deleveraging on lower volumes, pricing pressure, or both. Gross margin held relatively stable around 28-29% over the same period, suggesting the issue is volume and overhead absorption rather than unit economics erosion. The company is publicly traded, employee base of 501-1,000, and operates as an independent entity with no parent company or disclosed controlling shareholder.
