The Sand Casting Process
Quaker City Castings utilizes the Airset (No-bake) sand casting process for producing multiple types of metal casts including:
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.
Understanding Stainless Steel Sand Castings
Stainless steel sand castings are prized for their strength and corrosion resistance, making them ideal for applications where durability and longevity are critical, in industries like:
- Automotive
- Marine
- Food Processing
- Construction
At Quaker City Castings, we specialize in creating high-quality stainless steel sand castings using the Airset (No-bake) process. This method ensures that each casting is crafted with precision, meeting the stringent requirements of these industries.
The properties of stainless steel alloys, such as resistance to heat and corrosive environments, make them an excellent choice for parts that must withstand harsh conditions.
Advantages of Stainless Steel Castings in the No-Bake Process
The No-Bake sand casting process at Quaker City Castings allows for the production of stainless steel castings with complex shapes and intricate details that are often challenging to achieve with other metal forming techniques. This flexibility is due to the superior mold stability and the ability to control the cooling rates, which are crucial for optimizing the metallurgical properties of stainless steel.
Additionally, our facility’s capability to handle large-scale castings ensures that we can meet the diverse needs of our clients, providing everything from small, precision components to large, structural parts. With our expertise in metallurgy and process control, we ensure that every stainless steel casting meets the highest standards of quality and performance.
