The heat gun is controlled to direct a flow of heated air against an advanced composite workpiece at a predetermined temperature for a predetermined time period and upon cessation of the time period to thereafter direct an unheated flow of air against the advanced composite for a second period of time thereby causing a resin component of the advanced composite to flow within the composite in a prescribed manner and to cure to a desired hardness.Field of SearchWith power supply and voltage or current regulation or current control meansControlling or regulating plural separate distinct heating resistance elements(i.e., one control system for all elements) Combined manual and automatic regulating or control means Automatic regulating or control means Including semiconductor means (e.g., transistor) With current connection and/or disconnection means (e.g., switch) Automatically operated | |
