Sumitomo (SHI) Demag – Leading from the very beginning.

Sumitomo (SHI) Demag stands for tradition and innovation of excellent injection moulding technology from Germany and Japan. This combines strengths from the two countries that have made mechanical engineering the most successful in the world. The predecessor company of today's headquarters in Schwaig, Ankerwerk Gebr. Goller, was one of the pioneers of injection moulding technology and developed the world's first single-screw injection moulding machine in 1956. Our plant in Wiehe, Thuringia, has been building high-performance small machines since 1979 and, following comprehensive modernization, has developed into a leading specialist for small and medium-sized injection molding machines with clamping forces of up to 1,500 kN. Since 2008, we have been part of the Japanese Sumitomo Group and, together with our parent company Sumitomo Heavy Industries, our plant in Ningbo, China, and our subsidiaries and sales partners, we supply customized solutions for plastics processing around the globe.
