What Masahide Seisakusho does

Masahide Seisakusho (株式会社正英製作所, dba SHOEI) is a Japanese privately-held industrial thermal equipment manufacturer founded in 1956 and incorporated in 1959, headquartered in Osaka with a global footprint spanning Japan, China, South Korea, Thailand, India, and Mexico through seven wholly-owned international subsidiaries and approximately 300 total employees (100 domestic, 200 overseas). The company designs, manufactures, and services three core product lines: combustion equipment (gas burners including hydrogen and ammonia burners, recuperator/regenerative burners, duct burners, surface combustion burners, and combustion control components), industrial furnaces (paint drying equipment, exhaust gas treatment systems such as RTOs and catalytic oxidizers, and industrial heating furnaces), and aluminum industrial furnaces (melting, holding, and heat treatment furnaces for the casting supply chain). Its underlying technology base rests on six decades of burner combustion engineering, heat exchange, regenerative combustion, and waste heat recovery — with proprietary architectures such as the STBW recuperator-integrated burner (approximately 25-30% fuel savings) and the RTR regenerative radiant tube burner (over 80% tube thermal efficiency).

SHOEI generates revenue primarily through one-time sales of custom-engineered burners, furnaces, and integrated systems (including installation and commissioning) sold via direct sales teams across seven domestic branch offices and overseas group companies, supplemented by recurring after-sales maintenance, inspection services, and replacement parts. Pricing is project-based and non-public; products are tailored to each customer's specification. Recent strategic emphasis has shifted decisively toward decarbonization, evidenced by the 2023 launch of the hydrogen combustion series (TRFH-H2, SMH-H2, SDC-H2) and the March 2025 launch of Japan's first ammonia-only combustion burner with built-in heat exchanger, supported by the 2023 opening of the Thermal Technology Research Institute. Customer segments are diversified across automotive manufacturing, food processing, coating/painting, steel and non-ferrous metals, glass processing, and general industrial plants, with a long-standing strategic relationship as a designated factory of Osaka Gas Co., Ltd. dating to the 1960s. The company is family-controlled (founder's family across three generations as Representative Director) and remains unlisted with ¥88 million registered capital.
