Farrar Corporation & Foundry

'''Farrar Corporation''' is an American [[iron]] [[foundry]] and [[machining]] company.

==AbOUT Farrar Corporation==
The Farrar Corporation has two locations: a [[ductile iron]] foundry and machining facility in [[Norwich, Kansas]] and a second machining facility in [[Manhattan, Kansas]]. Farrar has been in operation since 1931 and specializes in [[Pattern (casting)|machined ductile iron castings]] and assemblies. The foundry's capabilities include [[Pattern (casting)|casting design]] and technical assistance, [[Pattern (casting)|casting pattern design]], [[Cast iron|casting production]], [[heat treating]], casting painting and assembly as well as finish machining. Farrar is an [[ISO 9001:2000]] quality certified company.

==Ductile Iron Foundry==
The Farrar Corporation has poured all grades of [http://www.astm.org/Standards/A536.htm ASTM A536 Ductile Iron] since 1967 and specializes in castings of 2&nbsp;lbs - 70&nbsp;lbs in production runs of 100-100,000.<ref name="foundry">[http://farrarusa.com/specifications.html Exclusive Foundry Grades], Farrar Foundry Capabilities</ref> Farrar is unique{{POV-statement|date=April 2010}} in that its foundry is a nationally recognized producer of the highest quality [[Ductile iron|Austempered Ductile Iron (ADI)]]- iron that meets or exceeds the strength of steel.

The foundry is located in [[Norwich, Kansas]] with an adjoining machine shop that can provide its customers with turn-key casting solutions. The foundry frequently provides prototypes for customers' ductile iron castings that can help identify design flaws and weaknesses before that casting run is put into production. This unique{{POV-statement|date=April 2010}} ability allows Farrar to conserve resources and save its customers from making costly mistakes.

The plant is capable of handling 70 tons of melt per day with an anticipated expansion to 120 tons{{Or|date=April 2010}}.

==Ductile Iron Specifications==
Ductile iron is an economical alternative to steel due to its increased strength, improved performance and reduced cost. Below is a chart of the foundry's ductile (nodular) iron specifications:
