Abstract

The invention relates to a method for preheating a first molding surface (461) of a mold said mold comprising an open position and a closed position and defining in said closed position a closed cavity between said first preheated molding surface (461) and a second molding surface (462,762,861) characterized in that said method includes the steps of: a) inductively heating a part referred to as a core (470) outside the mold by placing said part inside a coil (430) having an AC current passing there through; b) inserting said core between the molding surfaces (461,462) of said mold in the open position; c) carrying out the preheating of the first molding surface (461) by transferring heat between said core and said molding surface; and d) removing the core (470) and closing the mold. The invention also relates to a device for implementing said method.
