There are various manufacturing processes and materials available for common mobile phone alloy casings, mid-plates, and middle frames. Among them, the die-casting forming process is one of the most common methods for producing aluminum alloy die castings.
Metal mobile phone casings, metal middle frames, and metal mid-plates—metal elements have seemingly become a standard configuration for mobile phones nowadays. From the high-end and sophisticated iPhone 7 to budget domestic models priced at just a few hundred yuan, a wide range of metal casings have become prevalent.
Metal mobile phone casings have even become a rigid criterion when purchasing mobile phones, as metal seems to be equated with quality. In fact, many mobile phone models are basically identical in appearance, but significant differences can be found upon opening the fuselage for close inspection.
High-quality metal mobile phone casings outperform low-end ones in both hand feel and service life, with a correspondingly higher price tag. However, they do not appear much different externally, making it impossible for average users to distinguish between them. This invisibly creates difficulties for novice buyers when selecting mobile phones. What’s more, many "fake metal" products are mixed in the market, which all deserve our vigilance.
Suitable for surface treatments such as electroplating and spraying.
Does not absorb iron during melting and die-casting, does not corrode the die, and has no die adhesion.
Possesses excellent room-temperature mechanical properties and wear resistance.
Low melting point (melts at 385℃), enabling easy die-casting forming.
Superior casting performance, capable of die-casting precision parts with complex shapes and thin walls, resulting in castings with smooth surfaces.
