Aluminum die casting is a common manufacturing process used to create LED panels, which are used in a wide range of applications such as backlighting, signage, and display panels. Here are the general steps involved in the manufacturing process:

1. Design and Tooling: The first step in manufacturing an aluminum die cast LED panel is designing the panel and creating a mold tool. This involves designing the product in CAD software and then creating a mold tool using CNC machines.
2. Melting and Pouring: Once the mold tool is ready, the next step is melting the aluminum alloy and pouring it into the mold. The molten metal is injected into the mold at high pressure, and this pressure helps to ensure that the aluminum fills the mold and creates a precise, detailed panel.
3. Cooling and Ejecting: After the aluminum is poured into the mold, it is left to cool and solidify. Once the panel is solid, the mold is opened, and the panel is ejected from the mold.
4. Trimming and Finishing: Once the panel is ejected, it undergoes trimming and finishing. This involves removing any excess material and finishing the panel to achieve the desired surface finish.
5. Machining and Assembly: Depending on the design, some LED panels may require additional machining or assembly. Machining involves using CNC machines to create additional features on the panel, such as mounting holes or grooves. Assembly involves attaching LED components, wiring, and any other necessary components to the panel.
6. Testing and Quality Control: Before the LED panel is shipped to the customer, it undergoes testing and quality control checks to ensure that it meets the required specifications and standards.

Overall, aluminum die casting is a reliable and efficient process for manufacturing LED panels, and it can be used to create complex designs with high precision and consistency.
