Cast model to another model when returning from database

Background Information

I have a model called Product. The product can have 3 different stock methods: Serialize, Bulk and None.

• Serialize is chosen when every physical item has a barcode.
• Bulk is chosen when we care for the changes in quantities
• None is chosen when we want to include a product in the inventory but we don't care about the quantity.

What I want to do

I want to create those 3 models (Serialize, Bulk, None) and extend them to the Product. Then to be able to call something like Product::all() and get a collection like this:

Products [
   0   => Serialize[...]
   1   => Serialize[...]
   2   => Bulk[...]
   3   => None[...]
   ...
   500 => Bulk[...]
]

My problem

How can I make laravel cast each object to their respective classes automatically?
