  • COMPOSITE COMPONENT OF CLAD MATERIAL AND SYNTHETIC RESIN PART AND MANUFACTURING METHOD OF THE SAME
    Publication number: 20110287281
    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.
