Resin sand is the molding sand or core sand which is made of the Resin as the binder.
The resin sand undergoes irreversible crosslinking reactions and solidifies by the action of the curing agent, thereby giving the mold or core the necessary strength.
Resin sand has high strength after hardening, which is especially suitable for machine modeling, and can produce complex and thin-walled castings.
At present, the most commonly used resin sand type is Resin self-hardening sand, which is composed of mixing silica sand, resin and hardener.
Resin self- hardening sand has high strength, small dimensional deviation, good collapsibility, and low energy consumption.
The disadvantage of resin sand is that the binder (Resin)is expensive and pollutes the air.
