About Sumitomo (SHI) Demag
Sumitomo (SHI) Demag Plastics Machinery GmbH, headquartered in Schwaig near Nuremberg, is a manufacturer of injection moulding machines for plastics processing. The Japanese-German company was formed in 2008 through the merger of the injection moulding activities of Sumitomo Heavy Industries and the Demag Plastics Group and is wholly owned by Sumitomo Heavy Industries, Ltd. The main focus is on the development and manufacture of all-electric injection moulding machines; in addition, hybrid electro-hydraulic machines are produced. The product portfolio covers machines with clamping forces between 500 and 15,000 kN. With five plants in Japan, Germany and China and more than 3,000 employees, the company has a global presence; over 165,000 installed machines are running in all key markets of the industry. The machines are used particularly in the packaging, electronics, medical, automotive and consumer goods industries.
