Abstract
The present invention relates to a method for adjusting the temperature inside a rotational molding chamber, wherein plastic material present inside a mold is heated to cause the melting thereof and the subsequent molding into the desired shape. In particular, the invention relates to a method for adjusting the temperature to optimal values inside a rotational molding chamber, irrespective of the different configuration and arrangement of the stations responsible for carrying out the molding steps, using a hybrid heating system of the air conveyed inside the rotational molding chamber.
Claims8
