The metal casting industry is vital to the U.S. economy and national security. Cast metal components are used in the energy, automotive, aerospace, railroad, electronics, manufacturing, plumbing, construction, and other industries.

In the metal casting industry, the melting of metal accounts for approximately 55% of total energy costs. Other energy-intensive processes include core making, mold making, heat treatment, and post-cast activities.
