    • A sand casting facing composition comprises a dry mixture of about 77% fine sand, 5% binder, 6% green system sand and 12% burned system sand. The fine sand is mulled with 5.8% wt/wt oil per total dry mixture and catalyst at about 0.5% wt/wt. Preferably, fine sand and binder are mulled with oil, catalyst, green system sand and screened burned system. The mulled mixture is rested, mulled again and rested again before use as facing sand for achieving accurate reproduction of the pattern's fine detail. A method of preparing the mold and preserving fine detail comprises riddling the pattern with a thin layer of the facing sand composition, compacting, riddling with dry system sand and riddling with system sand before compacting about the periphery of the pattern. Final layers of system sand are applied and compacted over the entire pattern.
    • 砂面铸造的组合物包括约77%细砂,5%粘合剂,6%绿色系砂和12%燃烧体系砂的干混合物。 每个干混合物和催化剂以约0.5%wt / wt计,精细砂砂的重量为5.8%wt / wt。 优选地,细砂和粘合剂用油,催化剂,绿色系砂和筛选的烧制体系进行研磨。 将沉默的混合物放置,再次研磨并重新使用,以作为面砂,以实现图案精细细节的准确再现。 一种制备模具并保存精细细节的方法包括用面层砂组合物的薄层捣碎图案,压实,在干燥系统砂中捣碎,并在压实图案周边之前用系统砂捣碎。 系统砂的最终层在整个图案上施加和压实。
