St. Marys Foundry won the prestigious 2024 AFS/Casting Source Casting of the Year award for our 6,600-pound ductile iron power frame used in the fracking industry.

Let us put our experience to work for you


St. Marys Foundry features two, twenty-ton coreless induction furnaces. We utilize flask and pit molding with chemically-bonded sand to produce castings ranging from 1,000 lbs. to 60,000 lbs. We pour Gray Iron, Ductile Iron and Ni- Resist and customer-specific irons and provide all applicable heat treatments. You can count on our team of experienced foundry professionals to supply quality, on-time castings for a variety of applications.

No-Bake Sand Molding

In the no-bake process, sand is mixed with a chemical binder/catalyst system and then molded around the cope and drag halves of the pattern. After a specified period, the sand mixture hardens to form the mold halves and the pattern is drawn. Then, a refractory coating may be applied to both mold halves before they are brought together to form one complete mold for pouring.

Flask & Pit Molding

A flask is a metal frame used for making and holding a sand mold. For larger jobs, a pit instead of flasks is used. There are many sizes of flasks and pits. The size needed is determined by the pattern and amount of sand needed.
