Demag, purchased by Sumitomo in the early 2010s, started with wire coating extrudes in 1949. In 1969 Sumitomo made their first injection molding machine to be put on the market out of Japan. Sumitomo later opened their division in America in 1980.
We can supply any injection molding replacement screw for Sumitomo at a lower cost and faster lead time. Feel free to call if you have any questions.
