A mold includes a surface for molding a composite part, the surface including surface details, wherein the mold is made of phenolic material. ## Claims ### Claim 1 A mold comprising: a first region, a second region, and a third region situated between the first region and the second region; a mold surface located in the third region; and surface details located on the mold surface, wherein at least a portion of the surface details includes a plurality of recessed grooves and a plurality of recessed microgrooves located between the plurality of recessed grooves, wherein the plurality of recessed grooves are deeper than the plurality of recessed microgrooves; wherein the mold consisting essentially of a phenolic material and withstanding at least two tons of force for at least two cycles. ### Claim 2 (depends on 1) The mold of claim 1, wherein the third region includes a curvature that substantially matches a predefined roll radius and a predefined bulge radius of a golf club face. ### Claim 3 (depends on 1) The mold of claim 1, wherein the surface details are located within a first rim, and a second rim is located within the first rim and generally follows a contour of the first rim, wherein each of the first and second rims provides an angled trough located therebetween such that the first rim, the second rim, and the trough together form a shim mold. ### Claim 4 (depends on 3) The mold of claim 3, wherein each of the first and second rims is generally rectangular in shape except for having a keyed corner. ### Claim 5 (depends on 1) The mold of claim 1, further comprising a first ejection feature located in the first region and a second ejection feature located in the second region, wherein the first and second ejection features are configured to create respective ejection slots in an offspring mold produced by the mold, wherein the offspring mold contains reverse details mirroring the surface details of the mold. ### Claim 6 (depends on 1) The mold of claim 1, further comprising a characteristic time (CT) test pad located between two adjacent grooves. ### Claim 7 (depends on 6) The mold of claim 6, wherein at least some of the plurality of microgrooves are located on the CT test pad. ### Claim 8 (depends on 1) The mold of claim 1, wherein each microgroove has a first end and a second end, the microgroove having a largest depth relative to the surface at the first end and becoming linearly shallower until the second end. ### Claim 9 (depends on 1) The mold of claim 1, wherein consecutive microgrooves between two adjacent grooves form a repeating stair-step pattern. ### Claim 10 (depends on 9) The mold of claim 9, wherein the repeating stair-step pattern terminates at any one of the two adjacent grooves. ### Claim 11 (depends on 1) The mold of claim 1, wherein each groove has a depth ranging from 0.07 mm to 0.13 mm and a width ranging from 0.585 mm to 0.625 mm. ### Claim 12 (depends on 11) The mold of claim 11, wherein each groove has a depth about 0.10 mm and a width about 0.605 mm. ### Claim 13 (depends on 1) The mold of claim 1, wherein each microgroove has a depth ranging from 1 μm to 40 μm and a width ranging from 300 μm to 500 μm. ### Claim 14 (depends on 13) The mold of claim 13, wherein each microgroove has a depth ranging from 14 μm to 22 μm and a width ranging from 380 μm to 420 μm. ### Claim 15 (depends on 14) The mold of claim 14, wherein each microgroove has a depth about 18 μm and a width about 400 μm. ### Claim 16 (depends on 1) The mold of claim 1, wherein the plurality of microgrooves have non-uniform profiles.
