About CNSI Trading
CNSI is both a manufacturer and a trader; the factory (HBZT) is located in Hebei, China. The factory’s location is known for its best prices on the market. Beyond that, given today’s fast-paced trading process, CNSI built its team with a long-term goal: providing stable supplies rather than maximizing profits.
With CNSI, we have an engineering team with over 30 years in the Silicon Carbide industry and a management team that has run the warehouse successfully for decades. Our workshop is equipped with; 4 granulating spray towers, 2 isostatic pressing machines, 2 automatic pressing machines, 2 reaction-bonded sintering furnaces, 2 pressureless sintering furnaces, 2 CNC lathes, 8 CNC grinders, and 6 polishing machines.
