Abstract
A method of casting a hollow golf club head includes casting the crown with a plurality of thin regions having a thickness of less than 0.030 inch separated by a plurality of ribs. The ribs act as cast-in runners that enable the thin sections to be formed without voids despite the extremely thin cross-section. The crown may have an additional region of substantially uniform thickness that is substantially the same as the thickness of the ribs.
