What Duplo does

Duplo Seiko Corporation (デュプロ精工株式会社) is a Japanese industrial equipment manufacturer founded in August 1973 and headquartered in Kinokawa, Wakayama Prefecture. The company designs, develops, and manufactures paper processing and office automation equipment, with core product lines spanning cutter-creasers (DC-618, DC-648), high-speed mail sealers (PS-510/515 series), CIS camera-based barcode/OCR sheet readers (SR series) with companion sorters (RS series), envelope-making equipment (EM-800), edge-glue DM pressure sealers (GS-L800), camera inspection systems (Ci-200), and the RECOTiO line of office paper recycling machines that use a proprietary deinking process to convert used copy paper into white recycled paper without bleach. Underlying technology centers on proprietary paper feeding, paper processing, document transport, CIS-camera scanning, and deinking/papermaking know-how, backed by the #1 patent portfolio within Wakayama Prefecture.

The company serves four primary customer verticals: commercial and digital printing companies needing automated finishing; logistics and e-commerce fulfillment operations needing address verification and shipping automation; manufacturing and distribution firms needing form cutting and barcode reading; and corporate offices adopting RECOTiO for in-office paper recycling and ESG/CSR initiatives. Notable named enterprise customers include Pfizer, DINOS CORPORATION, Kobayashi Pharmaceutical, and 7office.

Revenue is generated primarily through one-time hardware sales of equipment manufactured in Japan and China (Duplo Shandong subsidiary), distributed exclusively through the Duplo Group sales company network in Japan and internationally (Duplo U.S.A., Duplo International Limited, Multigraf AG). Recurring revenue is supplemented by consumables (ink, masters, pressure paper, forms) and after-sales service through the same channel. The go-to-market combines direct enterprise field sales via regional Duplo sales companies with strong event-driven demand generation at major global print trade shows (drupa, PRINTING United Expo, IGAS, DGAS). Recent inorganic moves include the 2024 acquisition of Swiss-based Multigraf AG and the 2025 acquisition of UK-based Bar Graphic Machinery, extending the company's geographic reach and entering the flexible packaging finishing vertical.
