remaining tight to the hub. “In the weldment, where the hub
was cylindrical, you had a big gap when the blades were at a low angle,” the customer’s mechanical engineer explained. “Now we can curve the blades’ tails to match the outside of the hub, which helps with the perfor- mance of the fan.” Because the manufacturer pro-
duces ventilation systems in a wide range of sizes, the two fi rms have started to explore changing more hubs from weldments to castings. In addition to the lessons learned in this case, Pier’s time spent instructing the customer on the casting process continues to pay off . “Now that they’ve been through
this fi rst casting design, it will open a lot of doors for them,” Rice said. “T ey are looking at upcoming projects to see if there are casting opportunities right off the bat. It has opened their minds to a completely new process for their product.”
The original hub was a 34-piece steel weldment that required substantial labor.
