Aluminum Heat Sink Fin Structural Component

As a core component of thermal management systems, this elongated aluminum heat sink fin maximizes contact area with air or cooling media through its dense parallel rib design. The reserved connection flanges at both ends and side snap-fit slots facilitate secure installation and stacked layouts in energy storage battery packs, motor controllers, or industrial power modules.

For such thin-walled structures with fine teeth, the forming process requires strict control over fin verticality and spacing consistency to prevent collapse or deformation that could compromise heat dissipation efficiency. Leveraging 500T to 1600T hydraulic presses and precision stamping die development capabilities, our factory achieves full-process manufacturing from material cutting and progressive stamping to shaping. This ensures dimensional stability of the ribs and surface flatness during mass production.

Our Ningbo production base operates under an ISO 9001 certified quality system and is equipped with Hexagon CMMs and blue light scanners for high-precision inspection of flatness, hole position tolerances, and overall contours of long-dimensional parts. We support surface treatments such as electrophoresis and anodizing per drawing requirements to enhance corrosion resistance. Additionally, we collaborate with customers on engineering analysis, from mold development to automated stamping planning, meeting customized delivery needs in the automotive modification, new energy, and industrial automation sectors.
