SUNFUN Group specializes in intelligent and sustainable industrial development. Driving quality advancement in manufacturing across China and the globe through technological innovation, we are committed to creating green value for a better human life.
We have deep expertise in smart energy and smart manufacturing, consistently achieving breakthroughs in precision production. Our capabilities range from 0.001-mm precision machining to the manufacture of components weighing from 0.1 grams to 150 tons. We maintain energy consumption within 0.1% and implement fully intelligent process management—all supported by four decades of specialized experience!
Innovation is the foundation of the growth of our group. We have built an open and collaborative innovation ecosystem, partnering with governments, enterprises, universities, and institutions to enable cooperative innovation and shared value, injecting sustained momentum into the industry.<br/>
As an accredited technology enterprise with its own institute and talent academy, SUNFUN has completed more than ten national-level R&D tasks and undertaken major projects commissioned by agencies such as the NDRC, MOST, and MIIT.
For the most demanding high-temperature applications, sintered silicon carbide outperforms most metals, refractory materials and other ceramic materials.
The material's high thermal conductivity and low coefficient of thermal expansion endow it with excellent thermal shock resistance, enabling it to withstand rapid temperature changes without cracking or failure. Its maximum operating temperature in an atmospheric environment can reach 1800°C. At high temperatures, the strength of sintered silicon carbide actually increases, while that of other ceramics and metals rapidly decreases. It also has creep (stress deformation) resistance and oxidation resistance, making it highly suitable for long-term use in harsh, high-temperature industrial environments.
We can provide high-temperature equipment components, including thermocouple protection tubes, high-temperature test fixtures,high-temperature firing plates, furnace tubes, muffle tubes, muffle plates, etc.
