Abstract
An apparatus for strengthening weld lines in molded parts includes a mold body having a mold cavity formed within the mold body. A reciprocating pin extends along a longitudinal axis through the mold body. The reciprocating pin is adapted to reciprocate between a position flush with the inner surface of the mold cavity and a position slightly away from the mold cavity to displace material within the mold cavity and strengthen weld lines formed in the molded part.
