Method of manufacturing ABS resin molded part and ABS resin molded part

Abstract

An ABS resin molded part is manufactured by forming a molded part of an ABS resin into which a particulate filler is mixed, eluting butadiene particles from the surface of the molded part by etching, and forming a plating coat on the surface after the etching.

 said filler is carbon black.    
   
   
       5 . The method according to  claim 1 , wherein 
 an average particle diameter of said filler is 0.5 μm or less.    
   
   
       6 . The method according to  claim 1 , wherein 
 said ABS resin contains said filler at 0.1 wt % or more to 0.5 wt % or less.    
   
   
       7 . The method according to  claim 2 , wherein 
 a thickness of said plating coat is 10 μm or less.    
   
   
       8 . The method according to  claim 7 , wherein 
 said filler is carbon black.    
   
   
       9 . The method according to  claim 7 , wherein 
 an average particle diameter of said filler is 0.5 μm or less.    
   
   
       10 . The method according to  claim 7 , wherein 
 said ABS resin contains said filler at 0.1 wt % or more to 0.5 wt % or less.    
   
   
       11 . The method according to  claim 8 , wherein 
 an average particle diameter of said filler is 0.5 μm or less.    
   
   
       12 . The method according to  claim 11 , wherein 
 said ABS resin contains said filler at 0.1 wt % or more to 0.5 wt % or less.    
   
   
       13 . The method according to  claim 8 , wherein 
 said ABS resin contains said filler at 0.1 wt % or more to 0.5 wt % or less.    
   
   
       14 . An ABS resin molded part, wherein: 
 an ABS resin into which a particulate filler is mixed is injection molded;    butadiene particles is eluted from a surface of the injection molded ABS resin by etching; and    a plating coat is formed on the surface after the etching.    
   
   
       15 . The ABS resin molded part according to  claim 14 , wherein: 
 said ABS resin molded part includes a thick walled part and a thin walled part adjoining with each other; and    a thickness of said plating coat is 10 μm or less.    
   
   
       16 . The ABS resin molded part according to  claim 14 , wherein 
 said filler is carbon black with an average particle diameter of 0.5 μm or less.    
   
   
       17 . An ABS resin molded part, comprising: 
 an injection molded part made of an ABS resin into which a particulate filler is mixed;    etching pits formed on a surface of said injection molded part by etching butadiene particles; and    a plating coat formed on the surface of said injection molded part.    
   
   
       18 . The ABS resin molded part according to  claim 17 , wherein 
 said injection molded part includes a thick walled part and a thin walled part adjoining with each other.    
   
   
       19 . The ABS resin molded part according to  claim 17 , wherein 
 a thickness of said plating coat is 10 μm or less.    
   
   
       20 . The ABS resin molded part according to  claim 17 , wherein 
 said filler is carbon black.    
   
   
       21 . The ABS resin molded part according to  claim 17 , wherein 
 an average particle diameter of said filler is 0.5 μm or less.    
   
   
       22 . The ABS resin molded part according to  claim 17 , wherein 
 said ABS resin contains said filler at 0.1 wt % or more to 0.5 wt % or less.    
   
   
       23 . The ABS resin molded part according to  claim 18 , wherein 
 a thickness of said plating coat is 10 μm or less.
