ABSTRACT:
The rotational molding apparatus includes a main support member having at least one arm extending therefrom. Each arm of the apparatus is adapted to rotate enclosed articles being formed or coated about at least one axis. In order to cool the arms during operation, each of the arms includes a cooling channel extending down the length of the arm through which a cooling fluid is circulated. Each arm further includes a fluid return in communication with the cooling channel which receives the cooling fluid at the end of the arm and recirculates it back to the main support member so that the cooling fluid does not interfere with the rotational molding process.
