Clearing hard conditions transforms new value into trust. Under various harsh conditions, repeated test simulations are conducted. To enable utilization in regions around the world alongside the precision and high quality of products, a Quality Assurance Management Center was established in 1996. Experiments using the latest equipment, such as performance tests, are meticulously repeated, and the results are utilized not only in quality assurance plans but also in the development of new products. At DEC, which has consistently implemented development designs that anticipate technological evolution and connect to the future, a flexible design and manufacturing system based on user-specific specifications is being established to enhance responsiveness and better satisfy the diverse needs of domestic and international markets. Building on the extensive track record of power relays developed for power supply, DEC's more meticulous design and manufacturing create new value. The motto of "accumulating technology in all processes of development, design, manufacturing, and inspection," established since the company's founding, is still upheld today and is applied to the construction of a rational production line that merges production efficiency and safety. In actual manufacturing, a more waste-free production method is being advanced by utilizing CAD/CAM and CAE, integrating production systems with information systems.
