Method of making a metal-resin composite

摘要

A method for producing a metal-resin composite includes a coating step, an assembling step, and a heating step. The coating step coats at least part of the outer periphery of a solid metal first member with a foaming resin and a non-foaming resin. The assembling step disposes the first member within a hollow metal second member. The heating step heats an assembly of the second member within which the first member coated with the foaming resin and the non-foaming resin with the axes of the first member and the second member extending in the horizontal direction, and thus foams the foaming resin between the first member and the second member.

1. A method for producing a metal-resin composite, comprising the steps of:
coating at least part of a first member by a foamable resin and a non-foamable resin of a desired thickness, the first member being the outer periphery of a hollow or solid metal, the coating step being performed in at least one step; disposing the first member within a hollow metal second member; heating an assembly of the second member within which the first member coated with the foamable resin and the non-foamable resin is disposed with the axes of the first member and the second member extending in the horizontal direction, thereby foaming the foamable resin between the first member and the second member, to form the metal-resin composite, wherein the desired thickness of non-foamable resin is equal to a distance between the hollow second member and the first member in the formed metal-resin composite.
