In general, the working environment of foundries is bad, compared to other manufacturing industries. To improve this, dust collection facilities are installed or improved. However, they cannot be installed in some factories. Therefore, we attempted to change the sand type from natural silica sand to spherical artificial sand mold with furan resin to improve the working environment. Before switching, we investigated the problems that occur when switching to artificial sand and external shrinkage problems were found. After taking countermeasure against the problem, we changed the sand type. As a result, it was possible to reduce the amount of dust in the working environment, and the control class prescribed by the Ordinance on Prevention of Dust Hazard could be reduced from level 3 to level 2.
