Resin Coated Sand Mold Casting Process Investment ...

Resin sand is the molding sand (or core sand) prepared with resin as a binder. The resin coated sand casting is also called shell mold casting because the resin sand mold could be solid into a strong shell after heating of just at the room temperature (no-bake or self-hardening process), which is different from the green sand casting process.The use of furan resin as a binder for moulding sand ...
