Abstract: A machine and process for mass-manufacturing hollow plastic articles using a plurality of rotating mandrels in a single cassette head comprising the steps of coating the mandrels with a mold release formulation, heating the mandrels, immersing the mandrels into a fluidized bed of resin particles, heat fusing the resin coating on the mandrels, cooling the resin and the mandrels, stripping the plastic articles from the mandrels and cutting them to length. The machine has a rotating portion comprising several identical mandrel-containing heads and a stationary portion comprising an equal number of workstations, each workstation adapted to perform one of the process steps, the rotating portion simultaneously moving all of the mandrel-containing heads to interact sequentially with one workstation after another wherein each of the process steps is executed in turn.
