Consumer electronics metal frames are essentially miniaturized versions of industrial ‘metal skeleton enclosures.’ Their functions fully correspond—providing structural support, heat dissipation, EMI shielding, and durability. The only differences lie in scale (from data center cabinets down to smartphone mid-frames), materials (shifting from steel/copper to aluminum/stainless steel), and surface treatments (evolving from passivation/electroless nickel plating to anodizing/PVD).

Process Parity:​ Both rely on CNC machining​ as the primary manufacturing method, followed by metal finishing. This involves passivation or electroless nickel plating for copper parts, and anodizing or PVD for consumer electronics. Notably, premium aluminum frames occasionally utilize electroless nickel plating as an underlayer prior to anodizing to enhance wear resistance.

Shared Thermal Logic:​ Whether it is large-scale equipment utilizing copper cold plates integrated into a chassis, or smartphones using a metal mid-frame as a passive heat bridge, the principle remains identical: the metal structural component doubles as the thermal path
