Abstract
A preferred embodiment of the present invention includes a compression mold for forming an archery bow limb. The compression mold comprises a mold assembly defining a mold cavity for receiving a resin and fiber slug. The mold cavity defines a limb tip area with outer limb tip portions. The mold assembly defines the mold cavity in the shape of an archery bow limb. The mold assembly further comprises a protrusion formed in the mold cavity. The protrusion includes a crown configured to urge glass fibers in the slug into the outer limb tip portions. The protrusion forms a depression to be ground to form a limb tip slot in the archery bow limb. In preferred embodiments, the protrusion includes a middle tapered area having a summit. In preferred embodiments, the outer limb tip portions have a higher glass fiber density than a remainder of the archery bow limb.
