AIR SETALLOYS


In the table below, you will find a comprehensive list of the alloys we employ in the Air-Set molding process as well as their physical properties.  Exceptions regarding alloys utilized in this process may be made based on the quantity of castings requested by the customer, job size, etc. 

AIR-SETMOLDING


The Air-Set Molding process, commonly referred to as "No-Bake Molding", consists of sand molds created using a wood, metal, or plastic pattern.  Dry sand is mixed with a urethane binder (a fast curing adhesive) and deposited into a box containing the pattern and all necessary formers and inserts.  The sand mixture sets hard in a short time and the mold is then removed from the pattern.  After the Air-Set mold has cured, it is ready for pouring.


Similar to the Shell Core making process, Air-Set cores for forming internal passages in the castings can be made using the same process mentioned above.


The Air-Set Molding process creates molds with excellent dimensional stability.  The casting



surface finish is also of higher quality than other sand casting processes. 


As a general rule, Air-Set molding provides high dimensional accuracy, producing castings with dimensional tolerances of (±0.005-0.015).  This method of molding is optimal for cast components with higher complexities in low to medium volume runs.  Air-Set no bake molding is one of the most efficient and advanced sand casting techniques currently available.
