A method of forming a mold having cavities for molding loop-engageable,
hook-shaped fastener elements, includes: supporting a first plate having
an outer surface that defines a plane; manipulating a material-cutting
beam of a laser along a predetermined curved profile to cut a cavity into
the outer surface of the first plate, the predetermined curved profile
being generally hook-shaped, the cavity defined by a wall extending into
the first plate from the outer surface; in a series of subsequent
actions, repeatedly indexing the first plate relative to the laser to
direct the material-cutting beam at further positions on the first plate
and repeating the step of manipulating the material-cutting beam of the
laser relative to the first plate to form a series of cavities, each
having a hook-shaped profile; and positioning a second plate adjacent the
outer surface of the first plate, the second plate providing a side wall
surface for each of the cavities of the first plate, the first plate and
the second plate in combination forming a mold having cavities for
molding loop-engageable, hook-shaped fastener elements. Various methods
for aligning such mold plates in a fastener element molding apparatus are
also provided. A hook product includes a stem portion integrally molded
with and extending from a sheet-form base to a distal end, the stem
portion having a planar side; and a crook portion extending from the
distal end of the stem portion to overhang the sheet-form base in an
overhang direction, the crook portion having a flat planar side co-planar
with the planar side of the stem, and an upper surface extending upward
from an upper extent of the planar side of the crook portion to an apex.
