Apple is expected to announce the new iPhone 13 models later this year, potentially in September. While the devices will undergo a few physical changes, the general design of the device will remain the same across the entire lineup. For instance, the iPhone 13 and iPhone 13 Pro models will still feature a boxier design and the screen size would probably remain the same as well. However, you can check out the iPhone 13 series' molds that are usually used by case makers.

Leaker DuanRui has shared an image of the iPhone 13 molds of the entire lineup on Twitter and links to Weibo. As mentioned earlier, these molds are used by case makers so they can manufacture relevant cases before the device is officially released to the public. This saves them time to wait for the actual product to come out for which they would have to start the production process late.
