Quality control

Vingxia Tianjing Longding Silicon Carbide Co, Ltd. has established a modern quality testing center andis equipped with advanced testing equipment at home and abroad. The company strictly implements theSO9001 quality management system, from raw material entry, smelting, grading, processing to finishedproduct delivery, and the entire process quality tracking and monitoring, fully ensuring the productquality requirements required by customers.

Using domestic and foreign advanced silicon carbide processing and production equipment and cleaningmagnetic separation, shaping, screening process, independent optimization of process line configuration.with low production cost, stable product quality, in line with GB, JIS, FEPA, DIN and other differentstandards, greatly improve the market competitiveness of products.

The company's quality inspection center is equippedwith professional testing personnel, in addition toroutine testing items, it can also test special indica-tors such as S, P, Ti, AI,O,, CaO, MgO, etc. It is aresearch and development and innovation capabili-ties of the testing center.

The company uses silicon carbide smelted from anthracite, which has high SiC content, stablephysical and chemical indicators, and high crystallization density. High quality and dense siliconcarbide products have a content of up to 99.00%, a specific gravity greater than 3,20, and a bulkdensity greater than 1.65g/cm3.
