Abstract
A process and an apparatus obtain plastic molded objects according to a technique which consists of introducing the plastic into a silicone elastomer mold, then inserting this mold into a high frequency device comprising a turntable 'carrousel', a series of high frequency heating presses and a cooling device. The process is characterized by the introduction of plastic into one end of the mold in the form of liquid plastisol under low pressure, i.e., less than 1 Magapascal. The apparatus employs a carrousel, a mold having two male inserts and resting on the carrousel, vacuum-creating means and plastisol injection means.
