Method for the production of a molded part
First Claim
1. Method for the production of a molded part which comprises a base part having a plurality of layers and a thermoplastic or duroplastic synthetic material bonded therewith, comprising the steps offirstly, inserting at least two layers of the base part into a die and deforming the same with a first stamp to create a connection between these layers,subsequently, forming the bond of the base part with the thermoplastic or duroplastic synthetic material such that the thermoplastic or duroplastic synthetic material is deformed with a second separate stamp in the same die under a pressure to become flowable, or introduced already liquefied under pressure and forms a bond with the base part, andcarrying out the production of the base part and bonding of the thermoplastic or duroplastic synthetic material with the base part in the same die with said first and second separate stamps, whereinin one method step, at least two layers of the base part are inserted into a die and deformed therein so that a connection is created between these layers, and in another method step, a thermoplastic or duroplastic synthetic material is inserted into the die already liquefied and then forming a bond with the base part.

Abstract
The invention relates to a method for the production of a molded part which comprises a base part consisting of a plurality of layers and a thermoplastic or duroplastic synthetic material bonded therewith, the bond of the base part with the thermoplastic or duroplastic synthetic material being formed such that the thermoplastic or duroplastic synthetic material is deformed under a pressure to become flowable, or that it is introduced already liquefied under pressure and forms a bond with the base part. According to the invention, the production of the base part and the production of the bond of the thermoplastic or duroplastic synthetic material with the base part is carried out in the same die.

1. Method for the production of a molded part which comprises a base part having a plurality of layers and a thermoplastic or duroplastic synthetic material bonded therewith, comprising the steps of
firstly, inserting at least two layers of the base part into a die and deforming the same with a first stamp to create a connection between these layers, subsequently, forming the bond of the base part with the thermoplastic or duroplastic synthetic material such that the thermoplastic or duroplastic synthetic material is deformed with a second separate stamp in the same die under a pressure to become flowable, or introduced already liquefied under pressure and forms a bond with the base part, and carrying out the production of the base part and bonding of the thermoplastic or duroplastic synthetic material with the base part in the same die with said first and second separate stamps, wherein in one method step, at least two layers of the base part are inserted into a die and deformed therein so that a connection is created between these layers, and in another method step, a thermoplastic or duroplastic synthetic material is inserted into the die already liquefied and then forming a bond with the base part.
