ABSTRACT:
A mold and injection molding process for the production of a fishing lure having multiple, integral bristles extending vertically from the lure. The mold defines an internal cavity in communication with an injection port and a ventilation port. The internal cavity defines a fishing lure having a desired shape. The cavity contains a pair of porous halves that facilitate the formation of integral bristles. Molten material is injected into the cavity through the injection port while air escapes through the ventilation port. The molten material penetrates the porous insert to form the bristles. The bristles are concurrently and integrally molded with the rest of the lure. After curing, the fishing lure is removed from the mold.
