Used Sumitomo Injection Molding Machinery for Sale

Sumitomo Heavy Industries, Ltd. traces its origins to 1888, when a workshop was established to service the Besshi copper mine in Japan. The company incorporated as an independent entity in 1934 and, following a 1969 merger with Uraga Heavy Industries, became Sumitomo Heavy Industries, Ltd. Its Plastics Machinery Division entered the injection molding machine market in 1965 and has since grown into one of the largest producers of injection molding equipment in the world, selling more than 5,000 machines annually across a global production network spanning Japan, Germany, and China.

The division's flagship product line is its all-electric SE series, which spans from micro-molding machines to large-tonnage horizontal presses. The SE-EV-A and SE-EV-S-HD series cover standard to high-duty mid-range applications, while the high-speed SE-HSZ series targets thin-wall and packaging work. The SE-HS-CI and SE130D-CI are purpose-built two-shot machines for multi-material and multi-component molding. At the larger end of the range, the CL series — including the CL7000 and CL9000 — brings Sumitomo's all-electric direct-drive technology to high-tonnage, large-mold applications. Across all lines, the proprietary Zero-Molding system delivers low-pressure filling, reduced clamp force, and near-zero defect rates.

Sumitomo injection molding machines serve a broad range of demanding end markets. Automotive manufacturers rely on them for connectors, housings, and interior components. Medical device producers value their cleanroom compatibility and shot-to-shot repeatability for syringes, implants, and diagnostic components. Electronics and consumer goods manufacturers use them for tight-tolerance housings and connectors, while packaging processors depend on the high-speed SE-HSZ and CL platforms for thin-wall containers and closures.

Buyers seeking used Sumitomo injection molding machines are drawn to the brand's reputation for mechanical durability and long service life. The all-electric direct-drive architecture eliminates belts and hydraulic fluid, reducing wear points and maintenance costs over time. Energy consumption is significantly lower than comparable hydraulic machines, making even older SE and CL units attractive for facilities focused on operating costs. Strong parts availability through the worldwide Sumitomo (SHI) Demag service network, combined with consistent resale values, makes pre-owned Sumitomo equipment a practical choice for processors looking to expand capacity without new-machine lead times.
