Here is introduction content for the die casting from WIKIPEDIA:

Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mould cavity. The mould cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mould during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.

The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high-volume production. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small- to medium-sized castings, which is why die casting produces more castings than any other casting process . Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency.

We can see compared with extrusion aluminium profile LED street light , the die cast led street light can have more beautiful and complicated design ,  and the cost would be more cost-effective , as the die cast machine can make bulk production .
