ESCO Corporation is a manufacturer of engineered metal wearparts and components for industrial applications – including mining and construction. Since 1913, the privately held company has been headquartered in Portland, Oregon, USA, and currently has more than 4,900 employees and 25 manufacturing sites throughout the world. The company designs and manufactures a host of products including ground engaging tools (GET) for mining, construction products, conveying, rigging, dredging and other industrial applications. The company also owns two companies that design and manufacture specialty drilling tools for the oil and gas industry. == History == ESCO was founded in 1913 by Oregon businessman Charles (C.F.) Swigert as a local source of steel castings. The Electric Steel Foundry Company was founded on property once occupied by the 1905 Lewis and Clark Centennial Exposition. The foundry used an unusual modern furnace that was fired by electricity rather than coke making it the first of its kind in the western United States. During its first 30 years, ESCO was mainly a regional supplier of cast steel alloy products for the logging, construction, and pulp and paper industry throughout the Pacific Northwest. In the 1920s, the company expanded production to include cast steel alloy products like the Bardon choker hook, widely used in forestry. Further growth was sparked by the use of Hadfield manganese steel and the production of dragline excavator buckets. The ESCO trademark was first used in 1926 and eventually became the company’s new name. ESCO survived the Great Depression primarily as a jobbing foundry, making castings for sawmills, pulp and paper mills. In 1932, ESCO opened its first stainless steel industrial service center. During the 1940s, ESCO added new products to meet demand for supply valves, pump bodies, anchor chains and other components for warships and tanks. In 1946, ESCO developed the two piece tooth tooth system and, in 1948, the company entered the cable excavator bucket market. Due to the growing mining and construction markets after the war, ESCO launched new products and opened additional plants, sales offices, subsidiaries and licensees, including a midwest distribution facility in Danville, Illinois and a foundry in British Columbia. The company also adopted new manufacturing, inspection and metallurgical methods. The 1960s and 1970s, ESCO expanded the manufacture of dragline and shovel dipper buckets and teeth. The company also launched a two-piece Conical tooth system and began using the argon oxygen decarburization (AOD) and vacuum molding processes. During the 1970s, ESCO opened an automated foundry in Newton, Mississippi and a second Canadian foundry in Ontario. During the early 1980s, ESCO launched its Helilok pin and lock system and also acquired Gray-Syracuse and Concorde Castings—investment casting facilities serving the aerospace and power generation industries. In 1983 ESCO bought Hyster Company, and then sold it in 1989 to NACCO Industries. During the 1990s, ESCO expanded operations in the United States, the United Kingdom and Canada and entered a joint venture to manufacture products in China. The company also acquired Heflin Steel, producing wear liners and armor plate. ESCO also introduced the Super V tooth system. Additional acquisitions like Quality Steel are targeted to serve the oil sands market. ESCO has also added aerospace and power generation facilities in Belgium and Slovakia and built new facilities in Mexico and Xuzhou, China. In 2008, ESCO introduced the SV2 tooth system, the Whisler Plus hammerless locking system, and the Ultralok hammerless tooth system. In 2006 and 2008, ESCO was named among Oregon's most admired manufacturing companies, according to a ''Portland Business Journal'' survey of more than 2,000 Oregon CEOs. The company announced plans for an initial public offering in May 2011 that could raise as much as $175 million. The company canceled plans for an IPO in May 2013. On December 28th 2012 Esco Corporation sold Turbine Technologies Group (Esco-TTG) to Consolidated Precision Products (CPP). Sale consisted of Esco TT Belgium, Esco TT Cleveland, Esco TT Mexico, Esco TT Syracuse, Slovakia Plant, Esco Tempe Machining Facility and NY’s Oriscany Steel Treaters. CPP is a portfolio company of Warburg Pincus. ESCO announced the acquisition of Texas-based Ulterra Drilling Technologies L.P. in August 2012 in a deal estimated at $325 million. In 2014, ESCO acquired another Texas-based company, Stabiltec Downhole Tools, LLC., further adding to the company's oil and gas portfolio. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ESCO Corporation」の詳細全文を読む スポンサード リンク
