Neenah Orders New Sand-Prep Systems

Simpson to supply equipment, technology for new molding line

November 10, 2006 — Simpson Technologies Corp. reports news of a new contract it has earned from Neenah Foundry Co., for a sand-preparation system as part of a new molding line at the foundry in Neenah, WI. The tight-flask molding line is planned to begin operation in 2008.

Neenah Foundry is one of the largest producers of municipal products castings in the U.S.

Pointing out that it is a long-time supplier of equipment and technology to Neenah, Simpson explains that the new order includes process and control equipment for the new line, and will deliver approximately 280 tons/hour of highly controlled, specialized green sand. The equipment includes three Beardsley & Piper Model 100B-250 Speedmullors to be controlled by three Model #18Mk2/2502 Hartley Compactability controllers.

Also, Neenah will receive three Model 90Mk2-5 Hartley pneumatic bond-addition systems, controlled by the Model #18Mk2/2502 Compactability controllers, that will measure and inject bond directly into the Speedmullors. Simpson details that this bond-delivery method “has been shown to minimize losses of bond to the dust collection system in Speedmullors.”

John Andrews, vice president of manufacturing and COO of Neenah, stated: "Well mulled green sand with predictable and consistent properties will be essential to the success of our new molding line. We are confident that the equipment we have specified for the green sand preparation and control will meet our high expectations."
