Abstract: Various embodiments relate to plastic-metal junctions and methods of making the same via laser-assisted joining. The present invention provides a method of forming a junction between a metal form and a solid plastic. The method can include laser treating a surface of a metal form to generate a feature (e.g., a plurality of at least one of pores and grooves) in the surface of the metal, wherein the laser has an angle of incidence with the surface of the metal of other than 0 degrees. The method can include contacting the metal surface including the feature with a flowable resin composition. The method can include curing the flowable resin composition to form the solid plastic, to provide the junction between the metal form and the solid plastic.

Abstract: A method for forming a part in an injection mold includes heating a polymer material to a temperature greater than or equal to a polymer glass transition temperature; injecting the polymer material into the injection molding apparatus of any of the preceding claims while pressing together the stationary half mold surface and the moving half mold surface to form the molding cavity; cooling a surface of the molding cavity with the cooling system; separating the stationary half mold surface and the moving half mold surface; and moving the ejection block relative to the stationary half thereby pushing the part away from the stationary half molding surface and ejecting the part from the injection molding apparatus.
