Neenah Swing Frame Wins Casting of the Year

Green Sand Metal Casting of the Year Award 2019 CastExpo 3


This is the 2019 CastExpo Casting of the Year. It's a swing frame produced by the Neenah Foundry, in Neenah, Wisconsin. The material is ductile iron. The process is green sand. The weight is 25.6 lbs., 11.6 kilograms, 23.2 lbs. machined, 10.5 kilograms. 

Dimensions are 12 by 8 by 6.5 inches. The application is for a small tractor backbone attachment for light agricultural. Neenah's casting design was developed based on Amerequip's 11 piece laser cut welded assembly.

The focus of the casting design was to improve quality and minimize costs. The casting was designed to be made using a single core, in order to keep both cooling and piece price cost to a minimum.

The assembly features, including holes and mating surfaces, are machined into the casting instead of the current process, which uses laser cut welded pieces. This improved quality since the machine features can be held to tighter tolerances.

Highlights from the April 2019 MODERN CASTING Magazine

"The conversion of the compact utility tractor component from an 11-piece steel weldment to a single ductile iron casting was the result of a collaboration between companies with different backgrounds but common goals. 

BRIAN SANDALOW, ASSOCIATE EDITOR

AFS Corporate Member Neenah Foundry (Neenah, Wisconsin) and Amerequip Corporation (Kiel, Wisconsin) worked together on converting an 11-piece steel weldment into a single ductile iron casting. The new- swing frame, which is used on a compact utility tractor backhoe attachment, was the result of col­laboration of the two Wisconsin-based companies and resulted in an improvement of quality and efficiency. Not only did this casting bring a new customer to Neenah Foundry, it also brought Neenah the 2019 Casting of the Year award from the American Foundry Society and Metal Casting Design & Purchasing Magazine. Neenah was recognized for introducing a customer to the benefits of casting and converting a weldment into a cast component. The switch also helps Amerequip produce the part in a more efficient and cost-effective manner as it ramps up volume. "This is a good example of time saved in production that a casting can bring," one judge wrote. Awards and honors aside, the casting was the result of almost a year of collaboration between the two companies. And although they have some common links (Amerequip vice president of sales and engineering Timothy Dorn had worked in the foundry business), the two facilities are quite different. Neenah produces gray and ductile iron castings for both the municipal and industrial sectors. Amerequip is a custom equipment manufacturer focused on laser cutting, welding, machining and assembly of steel components. "There was a lot of learning on their end,"Neenah design engineer Chris Slinger said. "They were asking us for input as far as casting tolerances and porosity and draft. There was a lot of teaching that went along with working on this project." That challenge, along with a number of others, were overcome."
