Fitting part, in particular for a motor vehicle, and production process

Abstract

A grained vehicle interior fitting part comprises a smooth or pre-grained film on a physically foamed support layer. The film may be multi-layered, such as of polypropylenes. The structure may be made by placing a film in a die with a surface structure and film insert molded with a foaming support material which subsequently hardens.

1 . A process for producing a grained vehicle interior fitting part, wherein a smooth or pre-grained film is placed into a die provided with a surface structure and is film insert molded with a foaming support material which subsequently hardens. 
     
     
         2 . The process as claimed in  claim 1 , wherein the film is pre-structured with a fine grain structure. 
     
     
         3 . The process as claimed in  claim 1 , wherein the film is three-dimensionally shaped before being placed in. 
     
     
         4 . The process as claimed in  claim 1 , wherein the support material is introduced into the die as a melt. 
     
     
         5 . The process as claimed in  claim 4 , wherein the melt is charged with a propellant fluid. 
     
     
         6 . The process as claimed in  claim 5 , wherein charging of the melt takes place under pressure. 
     
     
         7 . The process as claimed in  claim 5 , wherein the support material expands in the die. 
     
     
         8 . The process as claimed in  claim 1 , wherein a point as remote from the film as possible is selected as an injection point. 
     
     
         9 . A vehicle interior fitting part that can be produced as claimed in  claim 1 . 
     
     
         10 . A vehicle interior fitting part having a grained film, wherein the film has a physically foamed support layer on its rear side. 
     
     
         11 . The vehicle interior fitting part as claimed in  claim 10 , wherein a visible side of the film has a lacquer coat. 
     
     
         12 . The vehicle interior fitting part as claimed in  claim 10 , wherein the film is of multi-layer form. 
     
     
         13 . The vehicle interior fitting part as claimed in  claim 10 , wherein the thickest point of the support layer is less than approximately 2.3 mm. 
     
     
         14 . The vehicle interior fitting part as claimed in  claim 1 , wherein the support layer is made from a polypropylene copolymer. 
     
     
         15 . The process as claimed in  claim 1 , wherein the film is pre-structured with a coarser grain structure formed during the film insert molding with a support material. 
     
     
         16 . The process as claimed in  claim 5 , wherein the propellant fluid is a propellant gas. 
     
     
         17 . The process as claimed in  claim 16 , wherein the propellant gas is CO 2  and/or N 2 . 
     
     
         18 . The vehicle interior fitting part as claimed in  claim 11 , wherein the visible side of the film has a PUR lacquer coat. 
     
     
         19 . The vehicle interior fitting part as claimed in  claim 12 , wherein the film comprises a plurality of layers of polypropylene. 
     
     
         20 . The vehicle interior fitting part as claimed in  claim 13 , wherein the thickest point of the support layer is less than approximately 1 mm.
