Dry sand is essentially the same as green sand but with the moisture removed. This type of sand is mixed with a binding agent, usually resin or phenolic compounds, which gives the mold increased strength and thermal stability. Dry sand molds are cured at high temperatures to harden, which makes them suitable for producing high-quality castings with smooth surfaces. As a result, dry sand casting is often utilized in non-ferrous metal casting applications and for precision parts where surface finish is critical.
