A Leading Global Company In The Field Of Welding Technology And Robotics

OTC DAIHEN Asia Co., Ltd.

OTC DAIHEN Asia Co., Ltd. was established in April 1989 as part of DAIHEN Corporation’s long-term strategy to expand its manufacturing footprint in Asia and respond to the rapid growth of industrial production in the ASEAN region. Commercial production began in 1990, with Thailand selected as the manufacturing base due to its skilled workforce, strong supply chain, and proximity to key regional markets.

In its early years, the company focused on the assembly and production of welding-related equipment and components. Over time, OTC DAIHEN Asia steadily expanded its technical capabilities, product portfolio, and production scale in line with market demand and technological advancements from its Japanese parent company.

Following the major flooding event in Thailand in 2011, the company strengthened its factory layout, risk management systems, and operational resilience. Since then, OTC DAIHEN Asia has continued to modernize its facilities and manufacturing processes, reinforcing its role as a reliable production hub within the global DAIHEN network.

Today, OTC DAIHEN Asia supplies products not only to the domestic Thai market but also to Japan, ASEAN countries, Asia-Pacific regions, Europe, and other global markets, supporting a wide range of industries including automotive, construction machinery, steel fabrication, and general manufacturing.
