Aluminum 6063 Anodizing Black Skived Fin Heat Sink For Big Power Led Ceiling Light

Quick Detail

Description

This heat sink is based aluminum profile 6063-T5 material to processing, first of all, we check the raw material dimension is fine or not, the second is that according to the drawing, use the CNC Gear shovel machine to do the dimension, the third is that accroding to the drawing, the forth is that use the CNC to do exact dimension, the fifth is do anodizing clear, the last step is riveting, and then inspection/packing. First inspection and patrol inspection are done in processing .

Notes

This is a skived fin heat sink

A Skived Heatsink is manufactured using a skiving machine that uses a blade to cut material in thin slices, and then push the skived fin up. For a heatsink application, the manufacture of ultra thin fins is possible, and we have produced fins as thin as .008”. The process allows high aspect ratios that provide greater surface area for maximum heat dissipation. We typically use this process for copper Skived heatsinks, however Aluminum Skiving is possible. As this is very easy to set up, typically there are minimal setup fees which allow for rapid prototyping of new designs. It is possible to machine additional features after the skiving process has been completed, but requires an experience to avoid stresses on the heatsink.

It is fairly easy to identify Skived Heatsink as the heatsink has a curve where the blade finishes its cut at the base of the heatsink as shown in the picture. In addition, the fins are not completely vertical, and curve slightly. This is more pronounced at the fins get taller. Typical width of the plate fin is 200 mm, but it is possible to manufacture up to 400 mm wide heatsinks by rotating the block of material and running a second pass with the curvature of the fins being in the opposite direction. As a Skived heatsink is manufactured from a long block of material, the only is no real limit to length of the heatsink is the length of the block. Different heights can be achieved by machining the block of material. Any excess material is recycled to reduce wastage. Typical Finishes for Aluminum skived heatsink are Anodization, or Nickel Plated. Typical finished for Copper Skived heatsinks are Anti-Oxidant, or Nickel Plated.

Fodor can offer copper skived fi heat sink and aluminum(AL1050/6063) skived fin heat sink.
