State-of-the-art production facilities deliver the world’s top level of quality, on which our customers have come to rely. We take pride in our three production bases at Muroran, Hiroshima, and Yokohama, which today and every day provide the world with advanced products and systems. At each of these plants, which are thoroughly streamlined and designed for the ultimate in effi ciency, numerous specialists take on the challenge of technology innovation. The qualities of JSW can be seen in these three plants, fully equipped with the production systems and staff to meet the diverse needs of the age, while striving for high precision and energy effi ciency. Total quality control (TQC) is of course pursued at all our plants. In 1974 we gained accreditation by the American Society of Mechanical Engineers (ASME) certifying that our nuclear reactor pressure vessels and materials, as well as our general pressure vessels and boilers, meet the highest quality standards of that organization, recognized all over the world. We were awarded the prestigious Deming Application Prize for quality control in 1983. Then in 1994 we earned ISO 9001 and 9002 certifi cation for international quality management (combined as ISO 9001 in 2002), and in 1998 we received ISO 14001 environmental management systems certifi cation, among other examples of the worldwide recognition our company has achieved for the excellence of our quality and manufacturing technology as well as our efforts to protect the environment.
Dedicated to technological innovations especially in the fields of plastics and mechatronics, the Hiroshima Plant with its leading-edge manufacturing and assembly lines produces world-renowned large-size pelletizers and extruders, film and sheet production systems, and the latest plastics injection molding machines. The plant also has long experience in manufacturing and developing artillery and other defense equipment.
