Exterior Surface Treatment Of IPhone 14: PVD Magnetron Sputtering

Exterior surface treatment of iPhone 14: PVD magnetron sputtering

The iPhone 14 series features a sleek, durable aero-grade aluminum design and comes in five colors: midnight, blue, Starlight, purple and red.

Many users said the iPhone products have a beautiful appearance, the material of the "advanced" technology and material of nature cannot leave it, in addition to the ultra-precision cutting slot (shape), nano injection (metal frame), anodic oxidation (aluminum box), high precision polishing, using proprietary high strength properties of the materials, and the surface of a core process: PVD magnetron sputtering.

Magnetron sputtering coating has always been the color attachment process used on the shell of high-end mobile phone models. It can form coatings with different color effects, which can greatly enhance the appearance of the metal texture of the product and improve the grade of the product. In 2017, for the first time on the iPhone X, Apple used the PVD coating process to stain the stainless steel center frame of the iPhone. In 2020, Apple also tested an updated version of the PVD process on the gold iPhone 12 Pro: High-power Pulsed Magnetron sputtering (HIPIMS).
