Method for producing mold |
| abstract |
In production of a mold with the reclaimed spherical molding sand having a sphericity of 0.95 or more and mainly composed of Al 2 O 3 together with the binder containing the acid-hardening resin and the hardening agent (I), at least one of the hardening agents (I) and (II) that is used in production of a mold from which the reclaimed molding sand is obtained contains the organic sulfonic acid, and in the hardening agent, a content of sulfuric acid is not more than 5% by weight and a content of phosphoric acid is not more than 5% by weight. |
