Abstract

A tooling system for moulding a work piece is provided The tooling system comprises a mould tool (4) having a tool surface divided into a plurality of individual temperature controlled tool zones (6), and a control system for controlling the temperature of the plurality of individual zones of a tool surface, the control system comprising, a memory means (14) for storing desired curing parameters for the work piece, a plurality of sensors (12) associated with the individual tool zones (6) that sense and output a signal indicative of a property of the work piece or the tool surface in each tool zone (6), a main processor (16) and a controller (18) The main processor (16) is programmed to monitor said output signals so as to monitor said property of the work piece or tool surface and to read the desired curing parameters from the memory means (14) The controller (′8) is programmed to receive said signals and to receive information relating to said desired curing parameters of each tool zone (6) and, based on the information received, to calculate and output a control solution to control a supply of heat to each individual tool zones (6) so as to heat or cool them The main processor (14) is programmed to compare the signals of the monitored property to the desired curing parameters, to identify trends in said monitored property and, if said trends indicate that the monitored property of a tool zone (6) will move out of a tolerance band of the desired curing parameters, to modify or distort the desired curing parameters read from the memory means (14) and to request a further control solution to obtain said modified or distorted curing parameters so as to maintain the monitored property within said desired tolerance band of the desired curing parameters.
