Product Introduction

 

Cold forged heat sinks is a manufacturing process in which the aluminum or copper heat sink is formed by using localized compressed forces. Fin arrays are formed by forcing raw material into a molding die by a punch. The process ensures that no air bubbles, porosity or any other impurities are trapped within the material and thus produces exceptionally high quality products.

The common material that used for pin fin heat sink is AL1070 and CU1100, yes, pin fin heat sink can be made not only of aluminium but also of copper. Pioneer Thermal also developed pin fin heat sink to be made with AL6063 for some certain structure and market.

Pin fin heat sink normally used for LED, camera etc., compare to extrusion heat sink, pin fin heat sink thermal performance is better and heat dissipation area is bigger. Pin fin heat sink surface treatment can be anodize, e-coating, painting, nickel plating, anti-oxidation.
