ABSTRACT:
A method of carrying out gravity mold casting, i.e., pouring of molten metal into a mold cavity under the force of gravity. This particular method features the application of a heating insulating coating or an equivalent coating on the surfaces of an area the cross-sectional area of which is larger than that of other sections of the cavity and where the metal flowing speed is slower than in other areas of the mold. The coating is effected before pouring metal into the cavity.
