Common methods of electronic product shell manufacturing

Release time:2024-01-30

When we are looking for an aluminum alloy shell processing factory to customize the shell, we must consider several aspects of the shell design, such as size, material, rating system, etc. However, most of us usually ignore the manufacturing process of electronic product shells. Generally speaking, materials determine which manufacturing method is effective.

The first: numerical control machining

Numerical control (CNC) machining is a general manufacturing method of building materials. It selects digital CAD files as direct guidance, so that tools can cut parts from raw materials. The advantage of this process is high repeatability and improved work efficiency - engineers can program the design scheme to multiple machines and produce parts of the same specification at the same time.

Compared with other manufacturing methods, CNC machining integrates geometric complexity into the design and provides ultra-high precision parts. The above two advantages are not found by other manufacturing methods before. Another advantage of CHC processing is that it provides a clean and beautiful electronic product shell, and the shell processed from a single metal workpiece will not have cracks. However, this method makes the material cost higher than we expected. Therefore, if you decide to adopt this method, you must fully consider the material cost.


Second: sheet metal processing

Sheet metal processing is an economic method to manufacture the shell of electronic products. This is because its material cost is lower than that of CNC machining. The lower material cost is partly due to the thin and light sheet metal, which can be transformed into an open shell through three processes.

Desktop computers and most outdoor electronic product covers are typical examples of sheet metal manufacturing. This method has enough durability to make up for the lack of aesthetics.

Third: injection molding

This method is a simple and efficient processing technology, which fills the molten plastic into the metal mold at high speed. This forming method can produce parts of the same specification in batches at the same time. Game controllers, displays and electronic keys are common and typical examples of injection molding.

Fourth: 3D printing

3D technology is one of the most modern technologies in the production of electronic product shells. In the manufacturing process, 3D printing provides more geometric degrees of freedom for the structure of the shell. For example, it can achieve internal shell channels that are difficult or impossible to bend.


Manufacturing method is also a very important factor that determines the characteristics of electronic products. The above four manufacturing methods have their own advantages and disadvantages. Please according toElectronic product shellIt is required to select the appropriate processing method.
