| description | A metallic mold for casting a vehicle wheel having openings in a periphery of a disk portion of the wheel comprises a first mold for forming that external side of the wheel which faces an outside of a vehicle when mounted thereon and a second mold for forming an internal side of the wheel. The first mold has those projections for forming the openings which abut the second mold. A high-hardness coating material is coated by electric discharge coating on at least those base portions of the projections which extend diametrically inwards of the wheel, among outer surfaces of the projections. A coating of a mold coating agent is formed on portions of sharp draft in the projections. The coating has a three-layer construction comprising an under coat coated with a mold coating agent consisting essentially of ceramics, a middle coat coated with a mold coating agent consisting essentially of a mixture of boron nitride with ceramics, and a top coat coated with a mold coating agent consisting essentially of titania. |
