When that customer went out of business, the metalcaster sought out new customers and being in Kansas, agriculture equipment was a natural fit. The basics of the company Ferroloy casts gray and ductile iron parts in Wichita, Kansas. Quality is key Ferroloy’s quality assurance program includes green sand control, Brinell hardness testing, tensile testing, chemical composition monitoring, and dimensional inspection. The importance of ag Ferroloy makes castings for a number of markets, but the largest portion is for the agriculture industry. One of many products Ferroloy cast these winches at its green sand molding facility in Wichita, Kansas.
