In this example, casting body side 3552 includes an outer rib section 3512 of rib 351, which may be similar to one or more of the outer rib sections of the rib, such as outer rib section 2612 of rib 261 ). The casting body side 3552 also includes a rib forming wall outer surface 2652 of the rib forming wall 265. The outer rib section 3512 and / or the rib forming wall outer surface 2652 can be cast directly through the mold during casting of the cast body 350, but can also be formed by the inner rib section 3511 and the rib forming wall inner surface 2651 Lt; / RTI > may be formed in a manner similar to that described below with respect to the formation of < RTI ID = 0.0 >

13) of method 3400 includes forming at least a portion of a first one of the one or more ribs and defining at least a portion of the rib-forming wall outer surface or rib-forming wall inner surface of the rib- Removing at least one sacrificial layer of the first cast body side of the cast body to expose the surface. 14, the first cast body side may be similar to side 3551 of cast body 350, and one or more sacrificial layers may be similar to one or more sacrificial layers 3590, A portion of the one rib may be similar to at least a portion of the inner rib section 3511 of the rib 351 and the first surface may be similar to the rib forming wall inner surface 2651. In another example, the first cast body side may be similar to the cast body side 3552, and a portion of the first rib may be similar to at least a portion of the outer rib section 3512 of the rib 351, The surface may be similar to the rib forming wall outer surface 2652.

At block 34212 (FIG. 13), removing one or more sacrificial layers of the first cast body side may be performed through a chemical etch process. 14, the mask 35111 may be attached to the outer edge of the inner rib section 3511, and then the sacrificial layer 3590 is removed to reach the rib forming wall inner surface 2651 A chemical etchant is applied to the cast body side 3551. In some instances, the mask 35111 may comprise a polyurethane paint material, a resistive film, a wax material, a tar material, a grease material, or other resistive material. In the same or different examples, the chemical etchant used in the chemical etch process may comprise, for example, hydrofluoric acid. In one embodiment where the material of the cast body 350 is a titanium material, the hydrofluoric acid chemical etchant may etch such titanium material at a rate that etches about 0.25 mm in about 25 minutes. In another example, one or more sacrificial layers may be removed from the casting body 350 by other methods, for example, through machining, laser etching, electrical discharge machining, electrolytic machining, and / or abrasive polishing.

In some instances, through the ability to remove a sacrificial layer, such as sacrificial layer 3590, after casting a cast body such as cast body 350 (Fig. 14), a rib- It is possible to form a reinforced rib-forming wall such as the reinforcing rib-forming wall 265, which may alternatively be thinner than can be realized using only casting. For example, casting body 350 may include casting body wall thickness 3555 (FIG. 14) of about 1.03 mm or less between casting body side 3551 and casting body side 3552 in some examples, In this embodiment, the casting body wall thickness 3555 is about 0.53 mm to about 0.64 mm. However, it may be difficult to cast a wall thickness that is thinner than that described above for the cast body wall thickness 3555, because the molten metal material flows toward or through the narrower cast conduit and / This makes it difficult to adequately fill a smaller mold gap in the mold. In the situation where the minimum thickness of cast wall thickness 3555 is constrained by the limitations of the casting process as described above, further reduction of the wall thickness can be achieved through the sacrificial layer removal method described above, It is allowed to form rib forming walls 265 with rib forming wall thickness 2655. [ Thus, through the ability to additionally remove a sacrificial layer such as a sacrificial layer 3590 or the like, a thinner, lighter rib forming area, which may include reinforcing ribs for structural integrity and / or durability, Is allowed. In addition, through removal of the sacrificial layer 359, it is permitted to relocate the mass to other regions of the golf club head to improve performance without increasing the total mass of the golf club head.

There may be instances where different blocks of the method 3400 can be combined into a single block or concurrently, and / or the order of the blocks may be changed. For example, in some instances, block 34211 may be performed concurrently with block 34100. There may also be instances where the method 3400 may include additional or different blocks. As an example, the method 3400 may include other blocks for attaching the faceplate to the body at block 34100. There may be instances where the method 3400 may include fewer blocks. For example, the golf club head 220 may be manufactured by casting and block 34212 may be removed. Other variations on the method 3400 may be implemented without departing from the scope of the present disclosure.
