A rotary molding machine comprising:
- a frame;
- a table rotatably mounted to the frame;
- a first drive for rotation of the table relative to the frame;
- the table configured to receive a plurality of molds mounted in a circular array thereon;
- a hot runner mounted to the table configured to connect the plurality of molds to an extruder;
