Features
1. High precision: using advanced stamping equipment and molds, the dimensional tolerance is strictly controlled, such as the hole spacing error can be controlled within ±0.05mm, ensuring the adaptability of power supply component assembly, making circuit connection and module installation more accurate, and improving the overall performance stability of the power supply.
2. Wide material adaptability: It can adapt to a variety of sheet metal materials such as cold-rolled steel plates, stainless steel, and aluminum alloys. Cold-rolled steel plates have high strength and can be used for power supply shells to enhance protection; stainless steel is corrosion-resistant and suitable for power supplies in harsh environments; aluminum alloys are light and have good heat dissipation, which helps portable power supplies reduce weight and thermal management.
3. Complex forming: It can realize complex structure stamping, such as the multiple bends and concave-convex positions of the internal bracket of the power supply. Through one-time or continuous stamping, it reduces subsequent processes such as welding, improves production efficiency and structural strength, and makes the internal layout of the power supply more compact and reasonable.

4. Surface treatment compatibility: After stamping, it can be conveniently sprayed, electroplated, oxidized and other surface treatments. Spraying makes the power supply colorful and rust-proof; electroplating enhances conductivity and wear resistance; aluminum alloy oxidation forms a protective film, which combines beauty and protection, adapting to the appearance and protection requirements of different power supply application scenarios.

Product Details
Precision sheet metal stamping for power supplies is a key link in power supply manufacturing, and is produced around the structural parts of power supply equipment. From the design end, the size, opening, bending and other parameters of sheet metal parts are accurately planned according to the power supply power and functional module layout. During production, sheet metal plates of corresponding thickness and material are selected, and they are accurately stamped by CNC punching machines. The flat sheet metal is converted into power supply housings, internal brackets, heat sink fins and other components using molds.

Taking the power supply housing as an example, multiple sections of side bending are achieved through stamping to form a protective cavity. At the same time, the outlet holes and heat dissipation holes are accurately stamped, which not only ensures that the internal circuit of the power supply is isolated from the outside world, but also meets the cable connection and heat dissipation requirements. For the conductive connecting piece inside the power supply, the stamping process can ensure its uniform thickness and accurate contact area, improve the conductivity efficiency and reduce the power loss.

In terms of quality control, the stamped sheet metal parts need to undergo dimensional inspection and appearance inspection to ensure that there are no burrs, deformation, and the size meets the design standards. It is widely used in communication power supply, industrial power supply, consumer electronics power supply and other fields. With the advantages of high precision and multi-material adaptation, it provides structural support and performance guarantee for power supply products, and helps the power supply to achieve miniaturization, high efficiency and stable development. It is an important process bridge from power design concept to physical product, and promotes the continuous innovation and upgrading of the power supply industry in different application scenarios.
