Leaders from the start
Sumitomo (SHI) Demag represents tradition and excellence in innovation, blending the best injection moulding technology from Germany and Japan. We combine strengths from the two countries that have made mechanical engineering the most successful in the world. Besides our headquarter in Schwaig, Bavaria, our second plant in Wiehe, Thuringia, has been building high-performance small machines since 1969 and has developed into a leading competence center for small and medium-sized all-electric injection molding machines with clamping forces of up to 2,200 kN. Since 2008, we have been part of the Japanese Sumitomo Group. In collaboration with our parent company Sumitomo Heavy Industries, our China plant in Ningbo, and our subsidiaries and sales partners, we supply customised solutions to plastics processors across the globe.
