Abstract
A melt tank is disclosed having a plurality of cartridges wherein each cartridge is adapted to hold at least one molded part. An annular tank is provided having an open top while a substantially circular plate is coaxially rotatably mounted to the top of the annular tank. The circular plate includes a plurality of circumferentially spaced openings formed around its outer periphery wherein each opening is adapted to slidably receive and support one cartridge. The annular tank is filled with a heated liquid while a motor rotatably drives the plate with the molded parts immersed in the heated liquid. A robotic gantry selectively lifts the cartridges from the circular plate to enable the removal of finished melted out parts as well as the insertion of new molded over parts into the cartridges.
