Abstract: Investment-casting shells are disclosed that have at least one cluster of individual club-head casting molds for casting thin-walled, steel or steel-alloy club-heads at high process yield and low material usage. The shells have respective combinations of cluster configuration and number, gating, and runners, as determined systematically. Some shell configurations include a cluster of at least ten casting molds for respective club-heads each (a) having a head-volume less than 400 cm3, (b) defining at least one club-head wall having a thickness of less than 0.8 mm, and (c) defining at least one respective gate. The cluster is configured to produce a cast-product yield of greater than 80% at a material usage of less than 1,000 g, including process losses, per cast club-head. Also, at least one runner connects the gates together.

Abstract: A method of applying decorative layers to a steel golf club shaft is disclosed. The method may be performed on any type of steel shaft and comprises buffing the steel shaft, applying a primer or sealer coat, curing the sealer coat, buffing the sealer coat, applying a decal or decorative layer, applying clear coat over the shaft and decal, and curing the clear coat layer. Some embodiments comprise applying a layer of base coat color before applying a decal. Disclosed methods can, for example, improve adhesion between chrome-plated steel golf club shafts and paint, for golf club branding with increased resistance to wear.
