Four Common Ways to Customize Device Enclosures

When we are going to find a sheet metal processing factory to customize the casing of the equipment, we must consider several aspects of the casing design, such as size, material, rating system, etc. However, most of us generally ignore the manufacturing process of device casings. In general, the material determines which manufacturing method is most effective. Today, Huazhi Sheet Metal Processing Factory will list the common main manufacturing methods of sheet metal casings to help you learn more about custom equipment casings.


The first: CNC machining

Numerically controlled (CNC) machining is a common method of manufacturing building materials. It selects digital CAD files as direct guidance so that tools can cut parts from raw material. The advantage of this process is high repeatability and increased work efficiency—engineers can program designs onto multiple machines and can produce parts of the same specification simultaneously.

Compared to other manufacturing methods, CNC machining incorporates geometric complexity into the design and provides ultra-precise parts. The above two advantages are not found in other manufacturing methods before. Another benefit of CHC machining is that it provides a clean and aesthetically pleasing equipment enclosure that is free from cracks when machined from a single piece of metal. However, this approach made the material cost higher than we expected. Therefore, if you decide to adopt this method, you must fully consider the material cost.

The second: sheet metal processing

Sheet metal processing is an economical method of manufacturing equipment enclosures. This is because the material cost it produces is significantly lower than CNC machining methods. Part of the reason for the lower material cost is that sheet metal is thin and light, and sheet metal processing can transform sheet metal into an open enclosure in three steps.

Desktop computers and most outdoor electronic equipment enclosures are typical examples of sheet metal fabrication. This method has high enough durability to make up for the lack of aesthetics.


The third type: injection molding

This method is a simple and efficient processing technique that fills molten plastic into metal molds at high speed. This molding method can mass-produce parts of the same specification at the same time. Game controllers, monitors and electronic buttons are the most common and typical examples of injection molding.


Fourth: 3D printing

3D technology is one of the most modern technologies for producing equipment housings. During the manufacturing process, 3D printing provides more geometric freedom for the structure of the shell. For example, it enables inner shell channels that are extremely difficult or impossible to bend.


The final manufacturing method is also a very important factor in determining the characteristics of the device enclosure. Each of the above four manufacturing methods has advantages and disadvantages. Please select the processing method according to the shell requirements.
