Samsung on Friday published a new video that provides a closer look at how the glass edge on the Galaxy S6 Edge is formed.
The company has already explained a bit of the process in the past, and the extra steps have been blamed as one reason why Samsung might be struggling to make enough Galaxy S6 Edge units.
Samsung heats the glass to 800 degrees Celsius during a stage called “Thermal Forming,” when it bends the edges of the glass to create the final shape. Then, to make sure the glass is still strong enough, it runs it through a chemical strengthening process.
You can see a bit of the process, and some of Samsung’s machining of the metal Galaxy S6 Edge body, in the new promo video below.
