Iron & Metal Castings Done Fast
Providing our customers with the highest quality gray and ductile iron castings with 2 to 3 week lead times.
Winnebago is a jobbing foundry producing gray and ductile iron castings from ounces to 3000 lb. Established in 1984 by Gary Anderson and Jed Weldon to serve the short-to-medium run casting markets with unparalleled customer service, short lead times and high casting quality.We pour gray iron in Class 20, 30 & 40 and ductile irons 60-40-18, 65-45-12, 80-55-06 and 100-70-03. We can produce high silicon, molybdenum alloyed ductile irons such as Cat 1E1299 and offer some specialty irons such as Hi-Sil Moly ductile iron.
At this time, Winnebago does not offer highly-alloyed materials such as Ni-Resist or Ni-Hard, nor do we pour carbon steels.
We can produce ductile to a variety of internal specifications of major manufacturers; Caterpillar, John Deere, CHN, etc.
We specialize in rapid turnaround on prototype castings with deliveries as short as two days and in one-off castings for repair parts.
