This paper is the results of an investigation of surface roughness produced in the painted mold and the paintless mold of steel castings. This outline is as follows:
(1) If there is not sand of too small size, the roughness of casting surface influence proportionally by roughness of mold.
(2) Crystal water in the paint must be eliminated, but bonding power is decreased.
(3) By application of magnesia brick and chrome brick, surface is fine comparatively.
(4) Surface is not fine by application of a good many iron oxide.
(5) Treatment of product is important.
(6) Paintless mold must be applied to every mold.
