Aluminum Heat Sink Manufacturing Services by Teamsworld
Aluminum heat sinks are essential components in electronic devices, dissipating heat to prevent overheating and system failure. Their excellent thermal conductivity, lightweight nature, durability, and corrosion resistance make them ideal for various applications, such as consumer electronics, electrocommunication devices, lighting fixtures, industrial equipment, and more.
Teamsworld offers high-quality aluminum heat sinks tailored to your specific needs, with diverse sizes, shapes, fin densities, and alloy options. Leveraging Design For Manufacturing (DFM) support, our services cover the entire production process. Our advanced equipment also helps to ensure precise tolerances, high reliability, and optimal thermal performance for your custom heat sinks.
Types of Aluminum Heat Sinks Available
Die-Cast Custom Heat Sink
Die-cast aluminum heat sinks are cost-effective options for medium to high-volume production. They are formed by injecting molten aluminum alloy into a mold under high pressure. This allows precise control when creating complex designs that are difficult to achieve through other methods, such as thin fins which can help enhance surface area for better heat dissipation.
Forged Custom Heat Sink
Forged aluminum heat sinks have exceptional material density and durability. They are manufactured through forging techniques that involve shaping heated aluminum under intense force, which can help them achieve improved mechanical properties suitable for demanding applications.
CNC Machined Custom Heat Sink
CNC-machined heat sinks provide versatility and precision in design, especially for low to medium-volume production. With computer-controlled machinery, these heat sinks can be created with intricate features such as custom cut-outs, through-holes, or complex contours to maintain tight tolerances and desired thermal performances.
Extruded Custom Heat Sink
Extruded heat sink offers cost-effectiveness for simple designs. Heat sink extrusion involves forcing heated aluminum through a die to create continuous profiles with enhanced surface area. Due to the relatively low labor requirements, this aluminum heat sink has a balanced combination of low manufacturing costs and reliable thermal performance.
Depending on the type of heat sink you choose, the dimensions can be as thin as 2mm and go up to 500mm in length. If you aren’t sure about your options, you may consult our team for advice. We will help you balance size and performance with tailored solutions.
Alloy Options for Aluminum Heat Sinks
Various aluminum alloys can be used to manufacture heat sinks with excellent strength-to-weight ratios and thermal capabilities.
