A forming ram assembly is presented for a container forming machine, which includes a turret assembly with a cam rail. The ram assembly includes a mounting rail for attaching to the turret assembly. A cam follower is mounted to the mounting rail and configured to rollably seat against the cam rail. Connected to the cam follower is a forming die which moves as the cam follower traverses the cam rail. A knockout tool is mounted inside the forming die and includes a stepped segment. A drive cylinder moves the knockout tool within the forming die. An O-ring is seated inside a complementary channel of the knockout tool. An annular knockout guide is seated on the stepped segment of the knockout tool, located between and abutting the O-ring and forming die.
