History of ESCO Corporation
ESCO Corporation was founded in 1913 by Oregon businessman Charles (C.F.) Swigert. He saw a need for a local source of steel castings and established the Electric Steel Foundry Company 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 -– thus 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 industries 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 use of Hadfield manganese steel and the production of dragline buckets. The “ESCO” trademark was first used in 1926 and eventually became the company’s new name.
ESCO survived the hard years of 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 engineers developed the first two-piece ("R") tooth system; and in 1948, the company entered the cable excavator bucket market.
Capitalizing on the growing mining and construction markets after the war, ESCO launched new products and opened additional plants, sales offices, subsidiaries and licensees around the world -– including a Midwest distribution facility (Danville, IL) and a new foundry in British Columbia. The company also embraced new manufacturing, inspection and metallurgical technologies, which allowed for the production of more sophisticated components.
The 1960s and 1970s were years of much growth for ESCO, and the company continued to launch many new products. Demand grew very strong for the company’s dragline and shovel dipper buckets and teeth, and ESCO launched a new, two-piece Conical tooth system. ESCO also became the first steel foundry to use the AOD (argon oxygen decarburization) process, creating alloys of great purity and toughness. The company also adopted a new vacuum molding process. During the 1970s, ESCO opened an automated foundry in Newton, Mississippi and a second Canadian foundry in Ontario. As recession wracked the economy during the early 1980s, ESCO focused on efficiency and improvement. The company launched a new Helilok pin and lock system during this period. By the close of the decade, ESCO acquired Gray-Syracuse and Concorde Castings, which were investment casting facilities serving the aerospace and power generation industries.
Strong economic conditions created capacity challenges for ESCO during the 1990s, and the company expanded operations throughout the United States, the United Kingdom and Canada. ESCO also entered a joint venture to manufacture products in China. The company acquired Heflin Steel, which added wear liner fabrication and armor plate capabilities. The new Super V tooth system was a well received new product.
As ESCO approaches its 100th year, acquisitions like Quality Steel allow ESCO to serve the oil sands market. The company has also added aerospace capabilities in Belgium and Slovakia and built new facilities in Mexico and China. The company launched several new products in recent years, including the SV2 and Whisler Plus hammerless locking system and the Ultralok hammerless tooth system.
