Frequently Asked Questions

Q What are the benefits of folded fin over traditional designs?

Folded fin heat sinks offer superior fin density and surface area compared to extrusion or stamping. The continuous folding process creates more fins per unit length with consistent spacing. Material waste is minimal, making it cost-effective for high-performance applications. The design flexibility allows for custom fold patterns optimized for specific airflow conditions.

Q How are folded fins attached to the base?

Folded fins are typically bonded to the base plate using thermal epoxy, soldering, or brazing methods. The attachment method depends on the material combination, operating temperature, and thermal performance requirements. We can recommend the optimal bonding technique based on your specific application needs and production volume.

Q What is the maximum length for folded fin heat sinks?

We can manufacture folded fin arrays up to 1000mm in continuous length. For longer requirements, multiple sections can be joined together. The optimal length depends on the material thickness, fin height, and mechanical stability requirements. Our engineering team can help determine the best configuration for your application.

Q Can folded fins be made from copper?

Yes, we manufacture folded fins from copper (C1100), aluminum alloys, and brass. Copper provides maximum thermal conductivity, making it ideal for high-power applications where thermal performance is critical. Copper folded fins are commonly used in LED lighting, power supplies, and industrial equipment requiring superior heat dissipation.

Q What is the minimum order quantity?

Minimum order quantities vary based on customization requirements and material specifications. For standard configurations, we can accommodate orders starting from 100 pieces. Custom designs may require higher minimums. We’re flexible and work with clients on prototype quantities for design validation before full production.

Q Do you provide thermal performance testing?

Yes, we offer comprehensive thermal testing services including thermal resistance measurement, CFD simulation, and real-world performance validation. We can test prototypes under your specified operating conditions and provide detailed reports with recommendations for design optimization. This ensures the heat sink meets your thermal requirements before production.
