摘要：
The resin-coated sand is produced by coating the surface of a refractory granular aggregate with a thermosetting resin and a thermoplastic resin. When using this resin-coated sand, a mold with a less rough surface can be produced by a RP molding apparatus. When using this mold made of the resin-coated sand, a casting with fewer gas defects can be produced.
