Neenah Foundry labored with Hoosier Sample Inc to transform an 11-piece, laser minimize welded swing body meeting right into a single-piece design utilizing an ExOne 3D printer. The brand new swing body weighs lower than the unique and took considerably much less time to manufacture.
The swing body is a utility tractor element made by Amerequip Company, a design and engineering firm that serves OEM prospects; they had been involved about lead instances for the swing body in order that they sought an alternate answer from Neenah Foundry, who contracted Hoosier Sample Inc to manufacture the casting core.
Conventional Casting Meets Fashionable 3D Printing
A silica sand binder jetting ExOne S-MAX system was employed to 3D print the ductile iron casting mildew. Your complete course of took solely two weeks to finish in comparison with the six weeks it could have taken to construct a core field utilizing conventional tooling strategies. They saved $5,000 by not having to construct the core field, and the solid swing arm additionally weighs 2.2 kilos lower than the previous welded model.
There are many 3D printers that may print metallic however there are nonetheless purposes the place it’s extra applicable to manufacture a metallic half with casting. ExOne’s sand-based S-MAX 3D printer is good for creating complicated and hole casting cores instantly from CAD information with out having to interrupt designs down into completely different tooling operations. It may construct elements as massive as 80 x 39 x 27 inches at a charge of as much as three cubic toes per hour, and it’s correct to zero.3mm.
After Amerequip completes testing of the swing arm, it will likely be used on the ultimate product in 2020. The casted swing arm was modern sufficient to earn Neenah Foundry the 2019 Casting of the 12 months award from the American Foundry Society.
