Designing products for die casting can be tricking.  This is especially true when design housings as it  has aesthetics and mechanical requirements. Thin-  wall enclosures can be particularly difficult and will  often require ribs and bosses on the interior for  added strength. Other external and internal features  such as draft angle is required for the easy of  ejecting the part after the die casting process. We  will also often see enclosures with connectors and  buttons on the sides which involves using sliding  cores on the die to cast those features onto the  parts.
