Hokkaido Sumiden Precision Co., Ltd. (Hokkaido Sumiden) is our production base for cemented carbide indexable inserts, main products of Sumitomo Electric's hardmetal business. Having initiated construction of a new plant in September 2011, Hokkaido Sumiden recently completed the plant, and commenced full operation today. On May 26, prior to full operation, a plant opening ceremony was held, with President Masayoshi Matsumoto and other relevant persons in attendance.

Since it began operations in 1980, Hokkaido Sumiden, a wholly owned subsidiary of Sumitomo Electric Hardmetal Corp. , has carried on integrated production of high-performance, high-quality indexable inserts, supplying them to users throughout the world. Cemented carbide indexable inserts are essential for machining all kinds of mechanical parts in the automotive, steel, shipbuilding and IT industries. Demand for the inserts has been increasing on a global scale due to economic development and growing automobile production especially in emerging economies.

Hokkaido Sumiden precisely meets this growing demand. Cemented carbide indexable inserts are produced through processes such as powder compaction, sintering, machining and coating. Hokkaido Sumiden began constructing the new plant to integrate these processes into super-high-efficiency lines and minimize in-process inventory; the plant was recently completed and begins full operation today. The super-high-efficiency line features thorough labor saving and efficient equipment placement, thereby achieving 100% and 30% increases in productivity per employee and productivity per unit plant floor area, respectively, as compared with conventional levels. Thanks to these improvements, the state-of-the-art line cuts the production lead time in half: 6 days for cemented carbide indexable inserts, as compared with the conventional line. Hokkaido Sumiden intends to meet the burgeoning demand for indexable inserts with revolutionary high-efficiency production and reduced delivery time.

On May 27, Hokkaido Sumiden held the annual Moss Phlox Festival to foster good relationships with local residents. The festival was graced with the presence of Hokkaido Governor Harumi Takahashi, who also visited the new plant.

The Sumitomo Electric Group will continue to support global manufacture, swiftly delivering high-quality cemented carbide indexable inserts to our customers throughout the world.
