METHOD FOR PRODUCING PLASTIC COMPONENTS, WHICH HAVE A HIGH MECHANICAL LOAD-BEARING CAPACITY, WITH A CORRECT FINAL CONTOUR

摘要

A method for producing plastic components, which have a high mechanical load-bearing capacity, with a correct final contour is disclosed. In the method an injection casting process is carried out in a first step using a thermoplastic molding compound in a closed tool consisting of a female die and a male die, a thermoplastic molding compound with a high viscosity being used in order to provide a sufficient seal of the tool or the cavity at the tool parting plane between the female die and the male die in comparison to a molding compound with an extremely low viscosity used in a second step. The cavity is increased prior to the second step such that the seal formed by the molding compound is fixed on or in the molding compound with the extremely low viscosity after said molding compound is injected and cured to such an extent that the molding compounds forms a composite component.
