An apparatus for compression molding sealing liners in premade closure shells includes a shell loader for presenting premade closure shells in sequence, a mold charge placement device for placing charges of liner material into the premade shells, and a vertical wheel molding machine for receiving the closure shells in sequence from the loader and compression molding the mold charges to form sealing liners within the closure shells. The vertical wheel molding machine preferably includes a wheel mounted for rotation around a horizontal axis and a plurality of angularly spaced molds disposed around the wheel. Each of the molds preferably includes a first mold segment and a second mold segment disposed radially outwardly of the first mold segment. One of the first and second mold segments, preferably the second mold segment, includes a nest for receiving a premade closure shell. The other of the first and second mold segments, preferably the first mold segment, includes a core for engaging and compression molding the mold charge of liner material within the shell.
