Keiyo Blanking Kogyo evolved from Diapress Co., Ltd., a blanking and pressing company established in 1973 with Mitsubishi Corporation as one of the investors. When Mr. Masaaki Ando acquired an equity stake in Diapress in 1980, the corporate name was changed to Keiyo Blanking Kogyo. In 2000, Keiyo Blanking Kogyo consolidated Ando Yodan Kogyo Co., Ltd., and MC Lasermax Co., Ltd., to bring Keiyo Blanking Kogyo to its present status.
The later expansion of its business made Keiyo Blanking Kogyo into an integrated composite processor with versatility unparalleled in the industry, having capabilities in all aspects of steel plates from blanking and pressing to fusion cutting, assembling, and painting.
What symbolizes the company's all-around superiority is its wide-ranging equipment, one of the most diverse lineups in this business sector. It includes a continuous blanking press line that is among the largest in the world, an unmanned laser cutter operated by a LAN system, a robot-controlled arc welding machine, a machining center permitting 24-hour unmanned operation, and a distribution center that can be controlled and rearranged without human attendance. These items far surpass those of other plate processors both in function and scale. Besides the plant at the headquarters in Ichihara, the Kimitsu Office adjoining the Kimitsu Works of Nippon Steel Corporation and the Ryugasaki Office in Ibaraki Prefecture perform various methods of plate processing. The company now works on about 10,000 tonnes of steel a month. The industries it serves are diverse, including construction machinery, which accounts for an approximately 30% share of the company's output; automotive (including trucks), approximately 20%; and civil engineering and construction, approximately 20%. The processed steel also goes to the builders of bridges, tanks, and ships.
President Noriyuki Sato, who was assigned to his present position in 2007 as the first person to lead the company from outside the founding family, says, "As domestic demand is slow to grow, we will secure our steady share in the market by enhancing the value added in terms of functions and processing, while strengthening our supply capacity to construction-machinery manufacturers who are expanding their business overseas."
Keiyo Blanking Kogyo has a 5% equity stake in Hangzhou Metal One Steel Plates Processing Co., Ltd. (HMOP), which Metal One set up in China in 2007. In 2008, Suzhou Metal One Steel Plates Processing Co., Ltd. (SMOP), a joint venture of Keiyo Blanking Kogyo and Metal One with equity stakes of 40% and 60% respectively, was established to undertake fusion cutting of plates for Caterpillar Inc. and other construction machinery manufacturers, and its new plant for can-making and painting began operation in September 2011. In India, India Metal One Steel Plate Processing Private Limited (IMOP) was set up in April 2011 to handle similar operations, and is now making steady preparations for entry into service in August 2012. Keiyo Blanking Kogyo's high technical capabilities and the know-how supporting them are shining brilliantly not only in Japan but all over the world.
