Ball socket with film backing

Abstract

A bearing shell for a ball and socket joint has a core made of plastic, which is jacketed by a film at least in some areas.

1 . A process for manufacturing a bearing shell, the process comprising the steps of: 
 placing a film into a mold;    injecting plastic behind the film to provide a plastic core backing with the film jacketing said core backing at least in some areas of said core backing.    
   
   
       2 . A process in accordance with  claim 1 , wherein said core backing is performed according to an injection molding process or according to a low-pressure processing process.  
   
   
       3 . A process in accordance with  claim 1 , wherein said film is preformed in a preceding step.  
   
   
       4 . A process in accordance with  claim 1 , wherein shaping of said film is performed by said mold.  
   
   
       5 . A process in accordance with  claim 4 , wherein a part of said mold shaping said film is heated.  
   
   
       6 . A process for manufacturing a bearing shell, the process comprising the steps of: 
 inserting a film into a mold;    injecting plastic behind the film after inserting said film into said mold such that said injected plastic forms a plastic core backing, said film engaging said core backing at least in some areas of said core backing to form an integral bearing shell structure.    
   
   
       7 . A process in accordance with  claim 6 , wherein said core backing is performed according to an injection molding process or according to a low-pressure processing process.  
   
   
       8 . A process in accordance with  claim 6 , wherein said film is preformed in a preceding step.  
   
   
       9 . A process in accordance with  claim 6 , wherein shaping of said film is performed by said mold.  
   
   
       10 . A process in accordance with  claim 9 , wherein a part of said mold shaping said film is heated.
