Abstract: During the production of reinforced and non-reinforced components (45) made of plastic, the plastic must be solidified after the molding. For this purpose, energy must be supplied to the component (45) to be produced. This has heretofore been performed by heating the mold (47) for producing the component (45).

The invention provides supplying the energy for solidifying the plastic of the component (45) to the plastic to be solidified by at least one optical fiber (51) in the component (45) to be produced. The solidification of the plastic can be accelerated by the direct energy introduction into the component (45) to be produced.
