Manufacturing processes profoundly influence the final form and performance of housings. Sheet metal forming is suitable for relatively simple metal housings, completed through stamping, bending, and welding; die casting is more suitable for complex-shaped aluminum alloy housings, achieving high structural integrity and production consistency; for plastic housings, injection molding is the mainstream method, with mold precision determining product details and assembly fit; while additive manufacturing, i.e., 3D printing technology, offers new possibilities for small-batch, highly complex prototypes or customized housings. Each process corresponds to different design constraints and economic batch sizes.
