ZONE-CONTROLLED HIGH-TEMPERATURE ELECTRIC HEATER FOR THE IMPLEMENTATION OF COMPOSITE MATERIALS

摘要

SHORT The present invention relates to heating equipment high temperature intended to be mounted on a rigid mechanical support (66), in particular a press table, for the manufacture of plastic products and composite materials, comprising a heat-distribution plate (60) heated multizone by a sub -module heater (61) having a plurality heating elements (62) shielded, flat, one-piece, by spacer blocks (63) and divided into at least three zones. Each heater element (61) comprises at least three resistors (X1, X2, X3). The heating zone are electrically powered independently by electronic means for supplying power by area in accordance with predetermined instructions by heating zone cooperating with temperature sensors. - Figure 21.
