Abstract
A method for producing a component including a plurality of hollow complex elements, includes: filling a plurality of molding cavities with a thermoplastic material, the mold being maintained at a first temperature, applying a hold pressure to the thermoplastic material while the mold is cooled to a second temperature, and interrupting the hold pressure on the thermoplastic material while the mold is cooled to a third temperature.
Claims9
A method for producing a component comprising a plurality of complex hollow elements, each having a shape tapering gradually between a base and an apex, the complex hollow elements being connected to one another by one or more adjacent edges, the method comprising:
- filling, by a thermoplastic material, of a plurality of moulding cavities of a mould having a shape corresponding to the shape of the complex hollow elements of the component to be produced, the mould being held at a first temperature greater than the setting temperature of the thermoplastic material, then applying a holding pressure on the thermoplastic material while the mould is cooled until reaching a second temperature, wherein said holding pressure is applied during a compacting step by the mould and wherein the mould starts closing during the filling and finishes closing during the compacting step, interrupting the holding pressure on the thermoplastic material while the mould is cooled until reaching a third temperature, and removing a complex multielement component comprising a plurality of complex hollow elements from the mould.
