Aluminum Stamping Power Supply Housing & Case

The stamping die has a high precision and can ensure that the dimensional accuracy of the shell is within a very small tolerance range. There are various electronic components inside the power supply, such as circuit boards, transformers, etc., which have strict requirements on the installation space. The precise shell size can ensure that these components can be accurately installed in the shell to avoid problems such as mutual squeezing, short circuits or poor connections caused by inappropriate space. For example, the size of the circuit board of a power supply is fixed, and the stamping shell can be designed accurately according to the size of the circuit board so that the circuit board can be tightly and safely installed in it.

Stamping shells are generally made of metal materials, such as steel plates, aluminum plates, etc. Metal materials themselves have good mechanical properties, and their strength and hardness will be further improved after stamping. The power supply may be subject to external forces such as collision and extrusion during use. The sturdy stamping shell can effectively protect the internal electronic components. For example, in the power supply in the computer host, if the host case is accidentally touched or subjected to a certain degree of vibration, the stamping metal shell can prevent the delicate electronic components inside from being damaged.

Metal stamping shells have a good shielding effect on electromagnetic interference (EMI). The power supply will generate electromagnetic radiation when working, and it is also susceptible to interference from external electromagnetic signals. The metal shell can form a closed electromagnetic shielding space to prevent the internal electromagnetic radiation from leaking outward, and also prevent the external electromagnetic signal from entering the interior. This is crucial for some electronic equipment with high requirements for electromagnetic compatibility, such as power supplies for medical equipment, communication equipment, etc. For example, in medical equipment in hospitals, if the electromagnetic signal of the power supply leaks, it may interfere with the normal operation of other precision equipment, and stamping metal shells can effectively avoid this situation.

The stamping process can produce a shell with good appearance quality. Through fine processing of the mold surface and subsequent surface treatment, such as electroplating, painting, etc., the surface of the shell can be made smooth and flat with good gloss and texture. This can not only enhance the beauty of the power supply product, but also enhance its corrosion resistance. For example, after the stamping shell of some high-end power supply products is electroplated, the surface presents a bright metal texture, which looks more upscale.
