How do I remove the manufacturers name from the order items name?

By default if a product name doesn’t contain the manufacturer name already, the manufacturer name is appended to the front of the product name when converting a cart item to an order item.

If you don’t want the manufacturer name appended to the product name you can set the static Aero\Cart\Models\OrderItem::$nameContainsManufacturer boolean to false:

\Aero\Cart\Models\OrderItem::$nameContainsManufacturer = false;
