    * High Heat Dissipation Performance
    By densely arranging numerous thin fins, the contact area with air is significantly increased, achieving efficient heat dissipation.

    * High Quality through Precision Machining
    Manufactured using A5052 aluminum material and precision machining with a 3-axis machining center. Achieves uniform fin shape and high dimensional accuracy.

    * Lightweight and Excellent Thermal Conductivity
    Utilizing A5052 aluminum alloy, it provides stable heat dissipation performance while ensuring lightness and corrosion resistance.

    * Designed for Easy Installation
    Mounting holes are located at both ends for easy integration into various devices and enclosures.

    * Short Lead Time
    With a processing system utilizing the CAM system "Mastercam," production is possible with a lead time of 4 days.

    * Suitable for Prototypes to Small-Batch Production
    As it can accommodate complex fin shapes, it is suitable for the production of prototypes and custom-spec heat sinks.

Size / capacity (English) Workpiece size: 135 × 75 × 25 mm
Material: A5052
Processing method: 3-axis cutting
Equipment used: 3-axis machining center
CAM software used: Mastercam
Reference price: ¥100,000
Lead time: 4 days
Notices (English) This heat sink is precision-machined from aluminum rather than extruded material. Its high-density fins provide excellent heat dissipation and appearance quality. Fin dimensions can be customized to meet specific thermal requirements, supporting applications from prototyping to pre-production. Pricing varies by machining conditions and quantity.
