Introduction

Folded fin heat sinks are widely used in applications requiring high heat dissipation within limited space.
As an OEM folded fin heat sink manufacturer, Awind Thermal provides custom aluminum or cpper folded fin heat sinks designed for efficient thermal performance, mechanical stability, and reliable mass production.

With in-house manufacturing and engineering support, we help customers develop folded fin heat sink solutions tailored to their specific thermal and structural requirements.

Why Choose Folded Fin Heat Sinks

Folded fin heat sinks are manufactured by folding thin aluminum sheets into continuous fins and bonding them to a base plate.
This structure offers several advantages:

• High fin density for improved heat dissipation

• Uniform airflow channels suitable for forced convection

• Lightweight aluminum construction

• Flexible fin geometry for custom thermal designs

Compared with traditional extrusion heat sinks, folded fin designs are especially suitable for medium to high power thermal applications where space efficiency is critical.

OEM & Custom Manufacturing Capability

As a professional folded fin heat sink factory, we support OEM and custom projects from concept to production.

Our capabilities include:

• Custom fin height, fin thickness, and fin density

• Aluminum material options suitable for folded fin structures

• Precision bonding between fins and base plate

• Support for customer drawings and thermal requirements

• Prototyping and volume production consistency

All folded fin heat sinks are produced under controlled manufacturing processes to ensure stable quality and repeatable performance.
