Hill Engineering admitted to Forging Industry Association

Hill Engineering was recently admitted to the Forging Industry Association (FIA). For more than 100 years, the FIA has been helping forging companies in North America to increase their global competitiveness. FIA’s producer member companies manufacture approximately 75% of the custom forgings volume produced in the United States, Canada and Mexico. Its supplier members manufacture materials and provide services used by the forging industry. Together, FIA’s 200 members comprise the only trade association dedicated to promoting and serving the forging industry in North America.
