Apple has invented a method for carrying out a “laser polishing” technique which could be used to help create future ceramic iPhones.
The company’s patent application covers an industrial process designed “for polishing a ceramic component using a laser.” The technique could be used to “produce a polished surface” on a wide range of materials, ranging from the white ceramic used for high-end Apple Watch Series 2 models to glass materials, like the reported casing being used for this year’s iPhone 8.
