Abstract
A molding arrangement and method, such as slush or rotational molding, for forming a thermoplastic shell or skin product. The mold arrangement includes a hollow mold housing provided with a mold shell thereon, which together define an air chamber located within the mold housing. A plurality of air flow control devices, such as centrifugal fans, are mounted within the mold housing and direct heated air into the air chamber through discharge channels defined within the mold housing. The mold arrangement also includes an elongate air supply and heating arrangement which generates heated air within the mold housing and along substantially the entire longitudinal extent thereof to effect uniform heating of the mold shell.
