Composite component of clad material and synthetic resin part and manufacturing method of the same

Abstract

A Clad material superimposed aluminum materials on stainless steel materials forms coating film by the electrodeposition coating on each whole surface of stainless steel material and aluminum material. A film of the aluminum material is removed by the irradiation of the laser beam, and the aluminum material of this region is exposed. Aluminum material is introduced into an injection molding machine after forming anodizing film. The synthetic resin part is formed with invading a synthetic resin to aperture of anodizing film. Then the composite component of clad material and synthetic resin part is produced.

1 . A manufacturing method for a composite component of clad material and synthetic resin part comprising the steps of:
 forming a film by the electrodeposition coating for the whole surface of a clad material having a aluminum material in at least one aspect;   removing a portion of the film formed on the surface of the aluminum material;   forming an anodizing film on the surface of the aluminum material which exposed by removing a film; and   joining a synthetic resin part to the clad material by pouring a part of the synthetic resin part into a lot of apertures of the anodizing film to form a composition component.   
     
     
         2 . A manufacturing method according to  claim 1 , wherein the removing a part of the film is to removing a film by the irradiation of the CO2 laser. 
     
     
         3 . A manufacturing method according to  claim 1 , further comprising the step of irradiating a laser beam to the first direction and removing the film in the shape of a rectilinear figure on the aluminum material, and moving the laser beam to the second direction which is approximately at right angles to the first course with the pitch of 0.01 mm to 0.2 mm. 
     
     
         4 . A manufacturing method according to  claim 1 , wherein the step of forming a film by the electrodeposition coating comprises forming a partial mask on a portion of the surface of the aluminum material, and forming a film on the whole surface of the clad material including on the partial mask;
 the step of removing a portion of the film comprises removing a portion of the film by dissolving the partial mask.   
     
     
         5 . A manufacturing method according to  claim 1 , wherein the anodizing film has a lot of apertures of 40 nm to 100 nm in diameter. 
     
     
         6 . A manufacturing method according to  claim 1 , wherein the synthetic resin part is formed by injection molding. 
     
     
         7 . A manufacturing method according to  claim 1 , further comprising:
 jointing the synthetic resin part and the anodizing film with pushing the synthetic resin part to the anodizing film while heating.   
     
     
         8 . A manufacturing method according to  claim 1 , wherein the clad material is superimposed the stainless steel material on the aluminum material. 
     
     
         9 . A composite component of clad material and synthetic resin part comprising:
 a clad material superimposed the stainless steel material on the aluminum material;   an anodizing film formed in a portion of the aluminum material;   a synthetic resin part joined to the clad material by pouring into apertures of the anodizing film.   
     
     
         10 . A composite component to  claim 9 , wherein the anodizing film is formed in the penumbra of the clad material; and the resin material is the nail to engage the clad material to other parts.
