Late 20th Century of Metal Casting

1970 is the Semi-Solid metal worker process (SSM) conceived at Massachusetts Institute of Technology. It combines elements of aspects of forging solutions.

1971 Japanese to develop V-Process molding. This method uses unbonded sand and vacuum. Rheocasting 1971 is being developed by Massachusetts Institute of Technology.

1971 passes US Congress Clean Air Act and OSHA, the Occupational Health and Safety Act.

The first production in 1972 is Austempered ductile iron (ADI) components produced by Wagner Castings Company.

1974 Fiat introduces the in-mold process for ductile iron treatment.

1976 is compacted graphite iron (CGI), iron with graphite particles elongated with rounded edges and roughened surfaces, developed in the UK has characteristics of both gray and ductile iron.

1982 The Hot Box into binder system.

1993 occurs first foundry applications of plasma ladle refiner (melting and refining in one vessel) at Maynard steel casting Company in Milwaukee, WI. Babcock and Wilcox
1995, Barberton, OH, patent lost foam vacuum casting process to produce stainless steel castings with low carbon content.

1996 cast metal matrix composites which was first used in automobile production model in brake rotors for the Lotus Elise.

1997 Electromagnetic casting process developed by Argonne and Inland Steel Corporation. Electromagnetic edge containment significantly reduces energy expenditure and costs in steel production.
