When your high-power electronics need to stay cool under pressure, you need a heatsink that's more than just a piece of metal. At RMT, we specialize in making custom extruded aluminum heatsinks that offer a perfect blend of smart design, proven performance, and solid reliability.
Cooling You Can Count On?
Our heatsinks are made from high-quality aluminum like 6063 alloy, which is great at moving heat away from sensitive component(thermal conductivity around 160-180 W/m·K) s . This means your IGBTs, power transistors, and other high-power parts can run cooler and last longer. The natural oxide layer on aluminum also helps it fight off rust, making it tough enough for different environments .
The RMT Difference: Control from Start to Finish?
What makes RMT really stand out is our control over the entire making process.This allows us to ensure high quality and offer true customization.
Precision Extrusion: We heat aluminum billets to a specific temperature (480-520°C) and push them through a custom-shaped die to create the heatsink profile.This process allows for fins with complex shapes that maximize the surface area for better cooling .
CNC Machining Center: After extrusion, precision machining of aluminum heatsinks creates mounting holes, threads and cutouts for perfect component fit.
Durable Surface Finish: We typically apply an anodized finish. This not only gives the heatsink a clean, protective layer that resists wear and corrosion but can also be done in different colors like black or bronze if needed.
Built for Your Project?
We know that one size doesn't fit all. Whether you need a special size, specific hole patterns, or a particular color, we can work with you to create a heatsink that meets your exact needs. Our team is here to help bring your design to life.
