      A vary capable small heatsink

      Posted by Len Flint on 23rd Jan 2015

      This heatsink is only a bit larger than the 'antique' ones I'm running out of, but does an amazing job of cooling. I incorporated a small 'computer' fan an inch above it, running at 9 instead of 12 volts, and a 4" piece of this sink, placed horizontally, is cooling a 45 watt LED chip with a temperature rise of only a few degrees. At this price, I'll definitely be buying more!

      Quality parts and one-stop shopping for machining

      Posted by Anonymous on 24th Sep 2013

      We've received heatsinks cut, drilled, and tapped. Quality of the extrusion and machining are excellent. Customer service is friendly and accommodating. Parts were machined and shipped quickly at a reasonable price. Couldn't ask for much more.

      Outstanding quality of material and workmanship

      Posted by Anonymous on 11th Jun 2013

      Had a few heatsinks created for an audio application. Material is top-notch and machining workmanship is high quality. All at a very reasonable price. I'll be using them for my production runs as well as any future projects.
