An Integrated Composite Processor of Steel Plates
Keiyo Blanking Kogyo Co., Ltd. performs a broad range of steel plate processing, including blanking, pressing to melt-cutting, press forming, machining, welding and painting. Leveraging its diverse array of equipment—including the world’s biggest continuous blanking press line—the company provides integrated, high-value-added composite processing services for construction and industrial machinery, cars and trucks, and civil engineers and building constructors.

In 1973, Mitsubishi Corporation and its partners jointly established the company’s predecessor, Diapress Co., Ltd., to handle pressing and blanking tasks. Masaaki Ando joined as a stockholder in 1980, and Diapress was renamed Keiyo Blanking Kogyo Co., Ltd.

Boasting the world’s largest 2,200-tf and 1,500-tf continuous blanking press lines—which are representative of its superior capabilities—Keiyo Blanking Kogyo can blank continuously from coil-shaped steel plates with a maximum thickness of 14 mm. The lines’ nonstop machining capability is a key reason for their high production and cost efficiency. The company built these huge blanking lines about forty years ago before all of its competitors did so, and in fact only a few other companies in the world have such equipment even today. Other notable features of Keiyo Blanking’s equipment that are paralleled by no others in the industry include a laser cutter permitting unmanned operation using a LAN system, robotized arc welding and a machining center that can run nonstop without human control.

The lines turn out some seven thousand tonnes of steel components a month, of which about 30 percent each goes to vehicle manufacturers and to civil engineering and construction, about 15 percent to construction machinery makers, and the rest to making bulk tanks and to builders of ships and bridges, among others.

Keiyo Blanking Kogyo has also proactively established processing facilities abroad jointly with Metal One to cope with the overseas production shift of its major clients, including construction machinery builders. Hangzhou Metal One Steel Plates Processing Co., Ltd. (HMOP) was set up in Hangzhou, China in 2007; Suzhou Metal One Steel Plates Processing Co., Ltd. (SMOP) in Suzhou, China followed in 2008; most recently, in 2011, India Metal One Steel Plate Processing Private Ltd. (IMOP) in India was set up. All three embody the company’s high technological capabilities and know-how.

Taking advantage of its integrated composite processing capability, the company started OEM production of LP gas bulk storage tanks for major tank manufacturers in 2015. In this line of business, Keiyo Blanking Kogyo is giving full play to its superior technological assets through in-house handling of everything from base metal coils, pressing, welding, assembling, painting, legally prescribed testing (X-ray examination, and pressure resistance and airtightness testing), component attachment to the finished product stage.

President Takeo Sakai says: “We plan to take advantage of our integrated composite plate processing capability and seize latent demand for auto components as well as earthquake-proof or earthquake-resistant components, which is now rising because of the Fundamental Plan for National Resilience.”
