Aluminum Dry Sand Casting
Dry sand casting, also known as air-set casting, no-bake casting, CO2 casting, and cold-box casting, is a precision casting process used for radical part geometries with deeper pockets, thin ribs, or very large sizes that green sand casting cannot produce. Pentz Cast Solutions offers aluminum dry sand casting, working with a range of aluminum alloys to produce products with higher as-cast and linear tolerances than the industry standard.
