Golf club head indicia and methods of generating the same
A golf club head includes a striking face, and a bottom portion secured to, and extending rearward of, the striking face. A top portion of the golf club head is secured to, and extends rearward of, the striking face. The top portion includes a substrate layer and a sealant layer disposed on the substrate layer. The sealant layer includes therein a roughened region defining visually identifiable indicia. According to another aspect, a method includes receiving a golf club head including a portion having a metal substrate layer and a sealant layer disposed thereon. A selection of a first indicia is received from among a plurality of indicia, and a masking is applied to one or more exterior surface regions of the portion based on the selection. A visual representation of the first indicia is generated on an exterior surface of the portion by media blasting the portion.
1. A method comprising:
receiving a golf club head comprising a portion having a metal substrate layer and a sealant layer disposed thereon;
receiving a selection of a first indicia from among a plurality of indicia;
applying a masking to one or more exterior surface regions of the portion of the golf club head based on the selection; and
generating a visual representation of the first indicia on an exterior surface of the portion by media blasting the portion of the golf club head, thereby forming a roughened region defining the first indicia within only the sealant layer, wherein the step of media blasting is carried out using media having a MOH Hardness no greater than 6.0.
2. The method of claim 1 , wherein the portion comprises the top portion of the golf club head.
3. The method of claim 1 , wherein the sealant layer comprises a thickness no greater than 200 μm.
4. The method of claim 1 , wherein the sealant layer comprises a thickness between 20 μm and 60 μm.
5. The method of claim 1 , wherein the sealant layer comprises a thickness, t, and a roughened region of the sealant layer comprises a maximum height Ry such that Ry is no greater than 0.6×t after media blasting the portion.
6. The method of claim 1 , wherein a roughened region of the sealant layer comprises an average surface roughness, Ra, no less than 10 μm after media blasting the portion.
7. The method of claim 1 , wherein the golf club head comprises a wood-type golf club head.
8. The method of claim 1 , wherein the substrate layer comprises titanium or titanium alloy.
9. A method comprising:
receiving a golf club head comprising a portion having a metal substrate layer and a sealant layer disposed thereon;
receiving a selection of a first indicia from among a plurality of indicia;
applying a masking to one or more exterior surface regions of the portion of the golf club head based on the selection; and
generating a visual representation of the first indicia on an exterior surface of the portion by media blasting the portion of the golf club head, thereby forming a roughened region defining the first indicia within only the sealant layer, wherein the step of media blasting is carried out using glass beads.
10. A method comprising:
receiving a golf club head comprising a portion having a metal substrate layer and a sealant layer disposed thereon;
receiving a selection of a first indicia from among a plurality of indicia;
applying a masking to one or more exterior surface regions of the portion of the golf club head based on the selection; and
generating a visual representation of the first indicia on an exterior surface of the portion by media blasting the portion of the golf club head, thereby forming a roughened region defining the first indicia within only the sealant layer, wherein the step of media blasting occurs at a blast pressure of no greater than 60 psi.
