Abstract
A molding machine apparatus and method for the production of thermoplastic skins or shells by means of what is generally known as rotational or slush molding. The tooling is heated uniformly, rapidly and efficiently by means of high velocity, hot air streams directed at the tooling which create turbulent flow on the surface of the tooling. The air stream is accelerated by means of adjustable nozzles and the air is circulated in the mold by means of a centrifugal fan.
