Warsaw Foundry Iron Casting Capabilities

Warsaw Foundry was founded in 1923 and later incorporated in 1949. For 100 years we have been providing quality iron castings to customers that serve multiple industries, including; automotive, agriculture, construction, energy, marine and municipal. Our molds are made from green sand and we
utilize wood, plastic, steel, and aluminum patterns that are provided by our customers to fit our automatic molding machines or conventional molding lines. Our automatic molding machines support flask sizes of 14″ x 19″ and 20″ x 24″. For flask sizes beyond the automatic equipment’s capabilities, we
utilize the conventional method of mold making for which pneumatic and semi-manual processes are needed. For jobs exceeding the conventional capabilities we will produce floor molds at a very low volume. The 5-ton induction furnace with a melting capacity of 1.6 tons per hour allows us to monitor pouring temperatures and forecast the grades of iron per by the part’s metallurgical requirements.
Supplementing our molding and melting capabilities is our shell core machines and our ability to assemble intricate cores for complicated castings. Additionally, we continue to produce cores the traditional way using oil sand and vertical stack baking oven. Warsaw Foundry is ISO 9001:2015 certified
and can comply with various industry quality standards.
