New Apple Patents Reveal a Manufacturing Process for creating 3D Liquid Metal Glass Device Housings and more


 

Today the US Patent & Trademark Office published a patent application from Apple that relates to techniques for making glass components for electronic devices. More particularly, the present embodiments relate to techniques in which a fluid such as a liquid metal or a molten salt is used to shape a glass workpiece. Devices made this way could include a HomePod, Home Control device, an iMac, MacBook, iPad or iPhone.

 

Apple’s patent includes techniques that can be used to shape a glass workpiece to produce a three-dimensional glass component. By the way of example, the three-dimensional glass component may be a glass cover member or a glass housing.

 

In some examples, the shape of the glass workpiece is modified using a forming technique in which a portion of the glass workpiece is molded between a mold tool and a heated fluid such as a liquid metal or a molten salt. The resulting molded glass workpiece may then be finished to produce the glass component.

 

Apple’s patent FIG. 6 below schematically shows a laser system #680 and an operation of scanning a beam #682 produced by the laser system. The laser system, which includes a processing head #681, is simplified for purposes of illustration in FIG. 6. The processing head and the transparent substrate #601 move relative to each other to scan the beam #682 along a path #661 on a front surface #602 of the transparent substrate.

Apple’s patent FIGS. 1A-B are just two simple device examples of three-dimensional glass components that may be a glass cover member or a glass housing.

 

Apple’s invention is extensively covered over two patents: (#1: 20220193825) “Laser-Based Cutting of Transparent Components for an Electronic Device,” and (#2: 20220194841) “Fluid Forming a Glass Component for a Portable Electronic Device.”

 

Considering that this is a patent application, the timing of such a product to market is unknown at this time.
