The Sand Casting Process

Quaker City Castings utilizes the Airset (No-bake) sand casting process for producing steel castings, stainless steel castings, ductile iron castings, and gray iron castings. In the No-Bake process, sand molds are formed using a wood or metal pattern. Fine-grain sand is combined with a resin binder in a high-speed mixer and then poured into a box containing the pattern. After a few minutes, the sand-binder mixture hardens and the mold is removed from the pattern. Cores for creating the inside structure of the castings are made using the same process, or with a material called chromite in certain parts. After the cores and the exterior molds are assembled, they are closed and prepared for metal pouring. Certain materials, such as ductile iron castings, require special treatment of the metal prior to pouring.
The No-Bake casting process is highly flexible as it allows iron castings and steel castings to be maintained to precise tolerances while also being able to handle part sizes from a few pounds up to tens of thousands of pounds.
