The described embodiment relates generally to the field of press-fit technology. Press-fit technology results in deformation of one component to lock another component in place. This deformation commonly causes surface strain to occur on the deforming component. When a component is anodized surface strain can result in anodization cracking; this ruins the finished appearance of cosmetic surfaces, generally resulting in ghosting lines and splotches appearing on the surface of a component. The described embodiment achieves a careful balance between component deformation and surface strain. By utilizing specific press-fit geometries and assembly methods, surface strain can be sufficiently limited to eliminate anodization cracking while also achieving a durable press-fit joint.

Such precise control of moisture and formaldehyde at curing is also achieved by superheated steam cure, moist-cure, which controls the same level of moisture throughout the curing process, or mild-cure with steam lower than 212 DEG F. (100 DEG C.).
