Our revolutionary product – the Friction Stir Welded (FSW) Heat Sink – is born to address this core challenge.
Your Professional Customized Heat Sink Manufacturer and Provider in China
Product Introduction:
In the era of high-performance electronics, thermal management has become a critical bottleneck. Traditional heat sinks often use mechanical fixation or brazing to attach fins to a baseplate, which inherently suffer from high interfacial thermal resistance and poor long-term reliability.
Our revolutionary product – the Friction Stir Welded (FSW) Heat Sink – is born to address this core challenge. This technology utilizes the frictional heat generated by a high-speed rotating tool to plasticize metal materials, creating a solid-state metallurgical bond. This process completely eliminates the gaps and interfaces found in traditional methods, resulting in a truly “seamlessly monolithic” cooling structure.
Core Advantages:
- Ultimate Thermal Conductivity: The metallurgical bond minimizes interfacial thermal resistance, providing an unobstructed path for heat transfer from the source to the fins, significantly boosting overall thermal performance.
- Exceptional Structural Strength: The weld strength can reach over 80% of the base material, offering superior resistance to vibration and shock, making it ideal for harsh environments like aerospace and automotive electronics.
- Defect-Free Bonding: The solid-state welding process avoids common defects found in fusion welding, such as pores and cracks, ensuring long-term stability and reliability.
This heat sink is the ideal solution for cooling high-performance computing servers, 5G base stations, and power semiconductors (e.g., IGBTs), providing rock-solid thermal protection for your equipment.

EIGHTBOND
aluminum products combine high quality with excellent price and feature an Italian design.
Our extensive range of aluminium profiles together with our experience and fast delivery time make us a very competitive company able to offer a great variety of bespoke solutions.
DARKROOMANDGONIOPHOTOMETER
Innovation and technology play a key role in our company. This is why we have recently installed a Dark Room with a Goniophotometer.
Light direction and intensity depend on many aspects, such as LED’s characteristics, the distance from the diffuser, the diffuser’s material, the shape of the profileitself.
In order not to neglect these factors and provide reliable results we have tested our aluminum profiles with each diffuser. Photometric tests have been carried out using 14,4W/m and 9,6W/m LED strips with chip LED 2835.
We can also carry out photometric tests on LED strips provided by customers.
Thanks to this extremely high-tech and latest generation device we are able to provide a valid support in choosing the most suitable profile for your lighting projects.
