Precision Laser Cutting for 0.4mm Magnetic Steel Sheet

Application: Heat Dissipation Fins / Radiator Fins

0.4mm magnetic stainless steel sheets are widely used for fabricating heat dissipation components, such as radiator fins and thermal interface structures in compact electronic systems. Precision laser cutting technology ensures tight tolerances and high repeatability for manufacturing complex thermal designs, especially in devices that require magnetic compatibility or shielding in addition to heat dissipation.

⚙️ Key Applications:

1. Heat Dissipation Fins (Radiator Fins):

• Laser-cut fins are used in power electronics, LED modules, battery packs, and communication equipment.

• Thin profile enables compact stacking, maximizing surface area for airflow and thermal conduction.

2. Thermal Interface Structures:

• Custom-cut patterns improve airflow dynamics and cooling efficiency.

• Magnetic stainless steel provides structural support while withstanding high operating temperatures.

✅ Advantages of Precision Laser Cutting:

• No mechanical deformation—ideal for maintaining flatness and fit of thin fins

• High repeatability—essential for mass-producing matched heat exchanger layers

• Clean, oxidation-free cuts—improves heat transfer efficiency and assembly quality

• Supports complex geometries like microchannels, vent patterns, and mounting slots

Typical Industries:

• Consumer electronics (laptops, phones)

• Telecommunication devices (5G base stations)

• Automotive electronics (EV cooling systems)

• Industrial control panels

• Medical imaging and monitoring equipment
