TECHNICAL

Urick Foundry utilizes the delayed inmold process in the production of all grades of Ductile Iron castings. This process is designed to provide optimal consistency of metallurgical properties as well as superior machinability. We have been very successful in reducing our customer’s cost by converting steel castings, forgings, stampings, or fabrications to Ductile Iron castings. To provide higher strengths we can supply all grades of Austempered Ductile Iron (ADI). Every single casting produced by Urick is tested with a resonant frequency test machine to insure that the % nodularity will exceed the SAE specifications. We are ISO 9001:2000 certified and have a history of providing unparalleled service and quality.
