An information handling system housing is manufactured from a laminate material having a stainless steel exterior and magnesium interior that are encapsulated with injection molding. A thin sheet of stainless steel is formed to have a lip that meets against the magnesium and is secured in place with injection molding material. In one embodiment, an injection molding tool holds the laminate material in place to encapsulate the perimeter of the material with injection molding material and also activates an adhesive that holds the laminate material together, such as by applying pressure and heat to the laminate material.
