Claim 16:
17. A method for manufacturing at least one thermoplastic part for integrating into a primary structure of an aircraft, the manufacturing method being carried out by using the system for manufacturing comprising:
a first molding member and a second molding member that cooperate along a vertical axis, wherein said first molding member comprising a first internal face comprising a first impression configured to give a surface condition to an upper face of the blank part and said second molding member comprising a second internal face comprising a second impression configured to give a surface condition to a lower face of the blank part,
a first heating body mounted to the first molding member along the vertical axis and configured to heat the first molding member through conduction to a heating temperature above 200° C. so as to heat the blank part through conduction to a temperature above the blank part's melting temperature,
a power supply device for the first heating body,
a first thermal insulation member positioned on the first heating body along the vertical axis and a second thermal insulation member positioned under the second molding member along the vertical axis, the first and second thermal insulation members defining an inner cavity in which the first and second molding members and the first heating body are positioned,
a flexible sealed envelope delimiting a closed volume in which the inner cavity having the first and second molding members, the first heating body, and the first and second thermal insulation members are positioned, and
a suction member configured to lower internal pressure in the closed volume of the flexible sealed envelope relative to external pressure external to the flexible sealed envelope so as to compress the blank part between the first and second molding members during heating of the blank part;, wherein said method comprising:
a step of placing the blank part between the first impression of the first molding member and the second impression of the second molding member,
a step of heating the first molding member with the first heating body through conduction to a heating temperature above 200° C. so as to heat the blank part through conduction to a temperature above the blank part's melting temperature, and
a step of depressurizing the closed volume during the heating step so as to compress the blank part between the first and molding members.
